OpenStack 集成

在一些情况下,用户需要使用 OpenStack 运行虚拟机,使用 Kubernetes 运行容器,并需要容器和虚机之间网络互通并处于统一控制平面下。如果 OpenStack Neutron 侧同样使用 OVN 作为底层网络控制,那么 Kube-OVN 可以使用集群互联和共享底层 OVN 两种方式打通 OpenStack 和 Kubernetes 的网络。

集群互联

该模式和使用 OVN-IC 进行多集群互联打通两个 Kubernetes 集群网络方式类似,只不过将集群两端换成 OpenStack 和 Kubernetes。

前提条件

  1. 自动互联模式下 OpenStack 和 Kubernetes 内的子网 CIDR 不能相互重叠。
  2. 需要存在一组机器可以被每个集群通过网络访问,用来部署跨集群互联的控制器。
  3. 每个集群需要有一组可以通过 IP 进行跨集群互访的机器作为之后的网关节点。
  4. 该方案只打通 Kubernetes 默认子网和 OpenStack 的选定 VPC。

部署 OVN-IC 数据库

使用下面的命令启动 OVN-IC 数据库:

docker run --name=ovn-ic-db -d --network=host -v /etc/ovn/:/etc/ovn -v /var/run/ovn:/var/run/ovn -v /var/log/ovn:/var/log/ovn kubeovn/kube-ovn:v1.12.12 bash start-ic-db.sh

使用 OVN-IC 进行多集群互联

Kube-OVN 支持通过 OVN-IC 将两个 Kubernetes 集群 Pod 网络打通,打通后的两个集群内的 Pod 可以通过 Pod IP 进行直接通信。 Kube-OVN 使用隧道对跨集群流量进行封装,两个集群之间只要存在一组 IP 可达的机器即可完成容器网络的互通。

该模式的多集群互联为 Overlay 网络功能,Underlay 网络如果想要实现集群互联需要底层基础设施做网络打通。

前提条件

  1. 1.11.16 之后版本部署的集群默认关闭了集群互联的开关,需要在部署脚本 install.sh 里修改下列变量:

    ENABLE_IC=true
    -

    打开开关后部署集群,会出现组件 deployment ovn-ic-controller。 2. 自动互联模式下不同集群的子网 CIDR 不能相互重叠,默认子网需在安装时配置为不重叠的网段。若存在重叠需参考后续手动互联过程,只能将不重叠网段打通。 3. 需要存在一组机器可以被每个集群的 kube-ovn-controller 通过 IP 访问,用来部署跨集群互联的控制器。 4. 每个集群需要有一组可以通过 IP 进行跨集群互访的机器作为之后的网关节点。 5. 该功能只对默认 VPC 生效,用户自定义 VPC 无法使用互联功能。

部署单节点 OVN-IC 数据库

在每个集群 kube-ovn-controller 可通过 IP 访问的机器上部署 OVN-IC 数据库,该节点将保存各个集群同步上来的网络配置信息。

Integration with OpenStack

In some cases, users need to run virtual machines with OpenStack and containers with Kubernetes, and need the network to interoperate between containers and virtual machines and be under a unified control plane. If the OpenStack Neutron side also uses OVN as the underlying network, then Kube-OVN can use either cluster interconnection or shared underlying OVN to connect the OpenStack and Kubernetes networks.

Cluster Interconnection

This pattern is similar to Cluster Inter-Connection with OVN-IC to connect two Kubernetes cluster networks, except that the two ends of the cluster are replaced with OpenStack and Kubernetes。

Prerequisites

  1. The subnet CIDRs within OpenStack and Kubernetes cannot overlap with each other in auto-route mode.
  2. A set of machines needs to exist that can be accessed by each cluster over the network and used to deploy controllers that interconnect across clusters.
  3. Each cluster needs to have a set of machines that can access each other across clusters via IP as the gateway nodes.
  4. This solution only connects to the Kubernetes default subnet with selected VPC in OpenStack.

Cluster Inter-Connection with OVN-IC

Kube-OVN supports interconnecting two Kubernetes cluster Pod networks via OVN-IC, and the Pods in the two clusters can communicate directly via Pod IPs . Kube-OVN uses tunnels to encapsulate cross-cluster traffic, allowing container networks to interconnect between two clusters as long as there is a set of IP reachable machines.

This mode of multi-cluster interconnection is for Overlay network. For Underlay network, it needs the underlying infrastructure to do the inter-connection work.

Prerequisites

  1. Clusters configured in versions after 1.11.16 have the cluster interconnection switch turned off by default. You need to mark the following in the configuration script install.sh:

    ENABLE_IC=true
    -

After opening the switch and deploying the cluster, the component deployment ovn-ic-controller will appear. 2. The subnet CIDRs within OpenStack and Kubernetes cannot overlap with each other in auto-interconnect mode. If there is overlap, you need to refer to the subsequent manual interconnection process, which can only connect non-overlapping Subnets. 3. A set of machines needs to exist that can be accessed by each cluster over the network and used to deploy controllers that interconnect across clusters. 4. Each cluster needs to have a set of machines that can access each other across clusters via IP as the gateway nodes. 5. This solution only connects to the Kubernetes default VPCs.

Deploy a single-node OVN-IC DB

Automatic Routing Mode

In auto-routing mode, each cluster synchronizes the CIDR information of the Subnet under its own default VPC to OVN-IC, so make sure there is no overlap between the Subnet CIDRs of the two clusters.

Highly Available OVN-IC DB Installation

A highly available cluster can be formed between OVN-IC DB via the Raft protocol, which requires a minimum of 3 nodes for this deployment model.

Highly Available OVN-IC DB Installation

A highly available cluster can be formed between OVN-IC DB via the Raft protocol, which requires a minimum of 3 nodes for this deployment model.

First start the leader of the OVN-IC DB on the first node.

Users deploying a docker environment can use the following command:

docker run --name=ovn-ic-db -d --network=host --privileged -v /etc/ovn/:/etc/ovn -v /var/run/ovn:/var/run/ovn -v /var/log/ovn:/var/log/ovn -e LOCAL_IP="192.168.65.3"  -e NODE_IPS="192.168.65.3,192.168.65.2,192.168.65.1"   kubeovn/kube-ovn:v1.12.13 bash start-ic-db.sh

Log in to the abnormal node and delete the database file:

mv /etc/origin/ovn/ovnnb_db.db /tmp
 

Delete the ovn-central pod of the corresponding node and wait for the cluster to recover:

kubectl delete pod -n kube-system ovn-central-xxxx
 

Recover when Total Cluster Failed

If the majority of the cluster nodes are broken and the leader cannot be elected, please refer to the following steps to recover.

Stop ovn-central

Record the current replicas of ovn-central and stop ovn-central to avoid new database changes that affect recovery:

kubectl scale deployment -n kube-system ovn-central --replicas=0
-

Select a Backup

As most of the nodes are damaged, the cluster needs to be rebuilt by recovering from one of the database files. If you have previously backed up the database you can use the previous backup file to restore it. If not you can use the following steps to generate a backup from an existing file.

Since the database file in the default folder is a cluster format database file containing information about the current cluster, you can't rebuild the database directly with this file, you need to use ovsdb-tool cluster-to-standalone to convert the format.

Select the first node in the ovn-central environment variable NODE_IPS to restore the database files. If the database file of the first node is corrupted, copy the file from the other machine /etc/origin/ovn to the first machine. Run the following command to generate a database file backup.

docker run -it -v /etc/origin/ovn:/etc/ovn kubeovn/kube-ovn:v1.12.12 bash

One-Click Installation

Kube-OVN provides a one-click installation script to help you quickly install a highly available, production-ready Kube-OVN container network with Overlay networking by default.

Helm Chart installation is supported since Kube-OVN v1.12.0, and the default deployment is Overlay networking.

If you need Underlay/Vlan networking as the default container network,please read Underlay Installation

Before installation please read Prerequisites first to make sure the environment is ready.

Script Installation

Download the installation script

We recommend using the stable release version for production environments, please use the following command to download:

wget https://raw.githubusercontent.com/kubeovn/kube-ovn/release-1.12/dist/images/install.sh

登录异常节点,删除对应的数据库文件:

mv /etc/origin/ovn/ovnnb_db.db /tmp
 

删除对应节点的 ovn-central Pod,等待集群自动恢复:

kubectl delete pod -n kube-system ovn-central-xxxx
 

集群不能正常工作下的恢复

若集群多数节点受损无法选举出 leader,请参照下面的步骤进行恢复。

停止 ovn-central

记录当前 ovn-central 副本数量,并停止 ovn-central 避免新的数据库变更影响恢复:

kubectl scale deployment -n kube-system ovn-central --replicas=0
-

选择备份

由于多数节点受损,需要从某个数据库文件进行恢复重建集群。如果之前备份过数据库 可使用之前的备份文件进行恢复。如果没有进行过备份可以使用下面的步骤从已有的数据库文件 中生成一个备份。

由于默认文件夹下的数据库文件为集群格式数据库文件,包含当前集群的信息,无法直接 用该文件重建数据库,需要使用 ovsdb-tool cluster-to-standalone 进行格式转换。

选择 ovn-central 环境变量 NODE_IPS 中排第一的节点恢复数据库文件, 如果第一个节点数据库文件已损坏,从其他机器 /etc/origin/ovn 下复制文件到第一台机器 , 执行下列命令生成数据库文件备份。

docker run -it -v /etc/origin/ovn:/etc/ovn kubeovn/kube-ovn:v1.12.12 bash

At some edge and 5G scenarios, there will be a lot of TCP communication between Pods on the same node. By using the open source istio-tcpip-bypass project from Intel, Pods can use the ability of eBPF to bypass the host's TCP/IP protocol stack and communicate directly through sockets, thereby greatly reducing latency and improving throughput.

"},{"location":"en/advance/accelerate-intra-node-tcp-with-ebpf/#basic-principle","title":"Basic Principle","text":"

At present, two Pods on the same host need to go through a lot of network stacks, including TCP/IP, netfilter, OVS, etc., as shown in the following figure:

istio-tcpip-bypass plugin can automatically analyze and identify TCP communication within the same host, and bypass the complex kernel stack so that socket data transmission can be performed directly to reduce network stack processing overhead, as shown in the following figure:

Due to the fact that this component can automatically identify TCP communication within the same host and optimize it. In the Service Mesh environment based on the proxy mode, this component can also enhance the performance of Service Mesh.

eBPF requires a kernel version of at least 5.4.0-74-generic. It is recommended to use Ubuntu 20.04 and Linux 5.4.0-74-generic kernel version for testing.

Deploy two performance test Pods on the same node. If there are multiple machines in the cluster, you need to specify nodeSelector:

Deploy the istio-tcpip-bypass plugin:

kubectl apply -f https://raw.githubusercontent.com/intel/istio-tcpip-bypass/main/bypass-tcpip-daemonset.yaml\n

Enter the perf client container again for performance testing:

According to the test results, the TCP latency will decrease by 40% ~ 60% under different packet sizes, and the throughput will increase by 40% ~ 80% when the packet size is greater than 1024 bytes.

Packet Size (byte) eBPF tcp_lat (us) Default tcp_lat (us) eBPF tcp_bw (Mb/s) Default tcp_bw(Mb/s) 1 20.2 44.5 1.36 4.27 4 20.2 48.7 5.48 16.7 16 19.6 41.6 21.7 63.5 64 18.8 41.3 96.8 201 256 19.2 36 395 539 1024 18.3 42.4 1360 846 4096 16.5 62.6 4460 2430 16384 20.2 58.8 9600 6900

In the hardware environment under test, when the packet size is less than 512 bytes, the throughput indicator optimized by eBPF is lower than the throughput under the default configuration. This situation may be related to the TCP aggregation optimization of the network card under the default configuration. If the application scenario is sensitive to small packet throughput, you need to test in the corresponding environment Determine whether to enable eBPF optimization. We will also optimize the throughput of eBPF TCP small packet scenarios in the future.

After deploying Hubble Relay, Hubble can provide complete cluster-wide network traffic observation.

"},{"location":"en/advance/cilium-hubble-observe/#configure-port-forwarding","title":"Configure port forwarding","text":"

In order to access the Hubble API normally, you need to create a port forwarding to forward the local request to the Hubble Service. You can execute the kubectl port-forward deployment/hubble-relay -n kube-system 4245:4245 command to open the port forwarding in the current terminal.

The port forwarding configuration can refer to Port Forwarding.

kubectl port-forward is a blocking command, you can open a new terminal to execute the following command to observe the traffic information.

After configuring the port forwarding, execute the hubble status command in the terminal. If there is an output similar to the following, the port forwarding configuration is correct, and you can use the command line to observe the traffic.

# hubble status\nHealthcheck (via localhost:4245): Ok\nCurrent/Max Flows: 8,190/8,190 (100.00%)\nFlows/s: 22.86\nConnected Nodes: 2/2\n

Execute the hubble observe command in the terminal to view the traffic information of the cluster.

The traffic observed by the cilium-test namespace is as follows:

Pay attention to the hubble observe command display result, which is the traffic information queried when the current command line is executed. Executing the command line multiple times can view different traffic information. For more detailed observation information, you can execute the hubble help observe command to view the detailed usage of Hubble CLI.

Execute the cilium status command to confirm that the Hubble UI has been successfully installed. In the second step of the Hubble installation, the installation of the UI has been supplemented.

Execute the command cilium hubble ui to automatically create port forwarding and map the hubble-ui service to the local port.

When the command is executed normally, the local browser will be automatically opened and jump to the Hubble UI interface. If it does not jump automatically, enter http://localhost:12000 in the browser to open the UI observation interface.

On the top left of the UI, select the cilium-test namespace to view the test traffic information provided by Cilium.

Look at the Cilium official document explanation, the CiliumNetworkPolicy resource limits the control at the namespace level. For more information, please refer to Cilium Limitations.

If there is a network policy rule match, only the Pod in the same namespace can access according to the rule, and the Pod in the other namespace is denied access by default.

If you want to implement cross-namespace access, you need to specify the namespace information in the rule.

Refer to the document, modify the CiliumNetworkPolicy resource, and add namespace information:

  ingress:\n  - fromEndpoints:\n    - matchLabels:\n        app: dynamic\n        k8s:io.kubernetes.pod.namespace: default    // control the Pod access in other namespace\n

Look at the modified CiliumNetworkPolicy resource information:

# kubectl get cnp -n test  -o yaml l3-rule\napiVersion: cilium.io/v2\nkind: CiliumNetworkPolicy\nmetadata:\n  name: l3-rule\n  namespace: test\nspec:\n  endpointSelector:\n    matchLabels:\n      app: test\n  ingress:\n  - fromEndpoints:\n    - matchLabels:\n        app: dynamic\n    - matchLabels:\n        app: dynamic\n        k8s:io.kubernetes.pod.namespace: default\n

Test the Pod access in the default namespace again, and the destination Pod access is normal:

# kubectl exec -it dynamic-7d8d7874f5-9v5c4 -n test -- bash\nbash-5.0# ping -c 3 10.16.0.41\nPING 10.16.0.41 (10.16.0.41): 56 data bytes\n64 bytes from 10.16.0.41: seq=0 ttl=64 time=2.383 ms\n64 bytes from 10.16.0.41: seq=1 ttl=64 time=0.115 ms\n64 bytes from 10.16.0.41: seq=2 ttl=64 time=0.142 ms\n\n--- 10.16.0.41 ping statistics ---\n3 packets transmitted, 3 packets received, 0% packet loss\nround-trip min/avg/max = 0.115/0.880/2.383 ms\n

Using the standard Kubernetes network policy networkpolicy, the test results show that Cilium also restricts access within the same namespace, and cross-namespace access is prohibited.

It is different from Kube-OVN implementation. Kube-OVN supports standard k8s network policy, which restricts the destination Pod in a specific namespace, but there is no namespace restriction on the source Pod. Any Pod that meets the restriction rules in any namespace can access the destination Pod.

After the network policy takes effect, cross-namespace access is still prohibited, which is consistent with the L3 network policy test results.

After the L4 network policy takes effect, ping cannot be used, but TCP access that meets the policy rules can be executed normally.

Now Kube-OVN extend the subnet to integrate with other different network plugins, so that other network plugins can also use the IPAM functionality of Kube-OVN.

"},{"location":"en/advance/multi-nic/#workflow","title":"Workflow","text":"

The above diagram shows how to manage the IP addresses of other network plugins via Kube-OVN. The eth0 NIC of the container is connected to the OVN network and the net1 NIC is connected to other CNI networks. The network definition for the net1 network is taken from the NetworkAttachmentDefinition resource definition in multus-cni.

When a Pod is created, kube-ovn-controller will get the Pod add event, find the corresponding Subnet according to the annotation in the Pod, then manage the address from it, and write the address information assigned to the Pod back to the Pod annotation.

The CNI on the container machine can configure kube-ovn-cni as the ipam plugin. kube-ovn-cni will read the Pod annotation and return the address information to the corresponding CNI plugin using the standard format of the CNI protocol.

In the Overlay Subnet under the default VPC, when the natOutgoing switch is turned on, all Pods in the subnet need to do SNAT to access the external network, but in some scenarios we do not want all Pods in the subnet to access the external network by SNAT.

So the NAT Policy Rule is to provide a way for users to decide which CIDRs or IPs in the subnet to access the external network need SNAT.

"},{"location":"en/advance/nat-policy-rule/#how-to-use-nat-policy-rules","title":"How to use NAT Policy Rules","text":"

Enable the natOutgoing switch in subnet.Spec, and add the field natOutgoingPolicyRules as follows:

spec:\n  natOutgoing: true\n  natOutgoingPolicyRules:\n    - action: forward\n      match:\n        srcIPs: 10.0.11.0/30,10.0.11.254\n    - action: nat\n      match:\n        srcIPs: 10.0.11.128/26\n        dstIPs: 114.114.114.114,8.8.8.8\n

The above case shows that there are two NAT policy rules:

  1. Packets with source IP 10.0.11.0/30 or 10.0.11.254 will not perform SNAT when accessing the external network.
  2. When a packet with source IP 10.0.11.128/26 and destination IP 114.114.114.114 or 8.8.8.8 accesses the external network, SNAT will be performed.

Field description:

action: The action that will be executed for packets that meets the corresponding conditions of the match. The action is divided into two types: forward and nat. When natOutgoingPolicyRules is not configured, packets are still SNAT by default.

match: Indicates the matching segment of the message, the matching segment includes srcIPs and dstIPs, here indicates the source IP and destination IP of the message from the subnet to the external network. match.srcIPs and match.dstIPs support multiple cidr and ip, separated by commas. If multiple match rules overlap, the action that is matched first will be executed according to the order of the natOutgoingPolicyRules array.

The reason for this step is to let the Pod regenerate /etc/resolv.conf so that the nameserver points to the local DNS IP.

Kube-OVN uses OVS for traffic forwarding in the final data plane, and the associated flow table matching, tunnel encapsulation and other functions are CPU-intensive, which consumes a lot of CPU resources and leads to higher latency and lower throughput under heavy traffic. Mellanox Accelerated Switching And Packet Processing (ASAP\u00b2) technology offloads OVS-related operations to an eSwitch within the eSwitch in the hardware. This technology can shorten the data path without modifying the OVS control plane, avoiding the use of host CPU resources, which dramatically reduce latency and significantly increase the throughput.

In some scenarios, the network environment does not support Underlay mode, but still need Pods and external devices directly access through IP, then you can use the routing method to connect the container network and the external.

Only Overlay Subnets in default VPC support this method. In this case, the Pod IP goes directly to the underlying network, which needs to disable IP checks for source and destination addresses.

"},{"location":"en/advance/overlay-with-route/#prerequisites","title":"Prerequisites","text":"
  • In this mode, the host needs to open the ip_forward.
  • Check if there is a Drop rule in the forward chain in the host iptables that should be modified for container-related traffic.
  • Due to the possibility of asymmetric routing, the host needs to allow packets with a ct status of INVALID.
"},{"location":"en/advance/overlay-with-route/#steps","title":"Steps","text":"

For subnets that require direct external routing, you need to set natOutgoing of the subnet to false to turn off nat mapping and make the Pod IP directly accessible to the external network.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: routed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: distributed\n  natOutgoing: false\n

At this point, the Pod's packets can reach the peer node via the host route, but the peer node does not yet know where the return packets should be sent to and needs to add a return route.

If the peer host and the container host are on the same Layer 2 network, we can add a static route directly to the peer host to point the next hop of the container network to any machine in the Kubernetes cluster.

ip route add 10.166.0.0/16 via 192.168.2.10 dev eth0\n

10.166.0.0/16 is the container subnet CIDR, and 192.168.2.10 is one node in the Kubernetes cluster.

If the peer host and the container host are not in the same layer 2 network, you need to configure the corresponding rules on the router.

Note: Specifying an IP for a single node may lead to single point of failure. To achieve fast failover, Keepalived can be used to set up a VIP for multiple nodes, and the next hop of the route can be directed to the VIP.

In some virtualized environments, the virtual network identifies asymmetric traffic as illegal traffic and drops it. In this case, you need to adjust the gatewayType of the Subnet to centralized and set the next hop to the IP of the gatewayNode node during route setup.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: routed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: centralized\n  gatewayNode: \"node1\"\n  natOutgoing: false\n

After the establishment is complete, you can capture packets and observe that the packets have been encrypted:

# tcpdump -i eth0 -nel esp\n10:01:40.349896 IP kube-ovn-worker > kube-ovn-control-plane.kind: ESP(spi=0xcc91322a,seq=0x13d0), length 156\n10:01:40.350015 IP kube-ovn-control-plane.kind > kube-ovn-worker: ESP(spi=0xc8df4221,seq=0x1d37), length 156\n

After executing the script, you can turn off IPsec by executing the command:

# bash ipsec.sh stop\n

Or execute the command to open it again:

# bash ipsec.sh start\n

This functions basically the same as ovn-eip-fip-snat.md .

As for the different parts, which will be specified in the following sections, mainly including the creation of ovn-eip of lsp type and the automatic maintenance of bfd as well as ecmp static routes based on vpc enable_bfd.

The above section is exactly the same with ovn-eip-fip-snat.md.

After these functions are verified, the vpc can be switched directly to the ecmp-based bfd static route based on the following way, or of course, switched directly back.

Before customizing vpc to use this feature, you need to provide some gateway nodes, at least 2. Note that the name of the current implementation of ovn-eip must be consistent with the gateway node name, no automated maintenance is currently done for this resource.

# cat gw-node-eip.yaml\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-1\nspec:\n  externalSubnet: external204\n  type: lsp\n\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-2\nspec:\n  externalSubnet: external204\n  type: lsp\n\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-3\nspec:\n  externalSubnet: external204\n  type: lsp\n

Since this scenario is currently designed for vpc ecmp out of the public network, the gateway node above will not trigger the creation of a gateway NIC when there is no vpc enabled bfd, i.e. when there is no ovn eip (lrp) with enable bfd labeled, and will not be able to successfully start listening to the bfd session on the other side.

note:

  1. Customize ecmp under vpc to use only static ecmp bfd routes. vpc enableBfd and subnet enableEcmp will only take effect if they are enabled at the same time, before static ecmp bfd routes are automatically managed.
  2. If the above configuration is turned off, it will automatically switch back to the regular default static route.
  3. This feature is not available for the default vpc, only custom vpc is supported, the default vpc has more complex policy routing.
  4. The enableEcmp of the subnet of the custom vpc uses only static routes, the gateway type gatewayType has no effect.
  5. When EnableExternal is turned off in vpc, the external network cannot be passed inside vpc.
  6. When EnableExternal is enabled on vpc, when EnableBfd is turned off, it will be based on the normal default route to the external network and will not have high availability.

In some cases the container network outperforms the host network, this is because the container network path is optimized to completely bypass netfilter. Due to the existence of kube-proxy, all packets in host network have to go through netfilter, which will lead to more CPU consumption, so that container network in some environments has better performance.

The L2 LB implementation of OVN requires calling the kernel's conntrack module and recirculate, resulting in a significant CPU overhead, which is tested to be around 20%.

Since the container network and the host network are on different network ns, the packets will pass through the netfilter module several times when they are transmitted across the host, which results in a CPU overhead of nearly 20%. The FastPath module can reduce CPU overhead by bypassing netfilter, since in most cases applications within a container network do not need to use the functionality of the netfilter module.

If you need to use the functions provided by netfilter such as iptables, ipvs, nftables, etc. in the container network, this module will disable the related functions.

Since kernel modules are kernel version dependent, it is not possible to provide a single kernel module artifact that adapts to all kernels. We pre-compiled the FastPath module for part of the kernels, which can be accessed by tunning-package.

You can also compile it manually, see Compiling FastPath Module

After obtaining the kernel module, you can load the FastPath module on each node using insmod kube_ovn_fastpath.ko and verify that the module was loaded successfully using dmesg:

OVS flow processing including hashing, matching, etc. consumes about 10% of the CPU resources.

It has been tested that the CPU consumption of flow-related operations is reduced to about 5% when the corresponding instruction set optimizations are enabled.

Similar to the compilation of the FastPath module, it is not possible to provide a single kernel module artifact for all kernels. Users need to compile manually or go to tunning-package to see if a compiled package is available for download.

"},{"location":"en/advance/performance-tuning/#using-stt-type-tunnel","title":"Using STT Type Tunnel","text":"

Common tunnel encapsulation protocols such as Geneve and Vxlan use the UDP protocol to encapsulate packets and are well supported in the kernel. However, when TCP packets are encapsulated using UDP, the optimization and offload features of modern operating systems and network cards for the TCP protocol do not work well, resulting in a significant drop in TCP throughput. In some virtualization scenarios, due to CPU limitations, TCP packet throughput may even be a tenth of that of the host network.

STT provides an innovative tunneling protocol that uses TCP formatted header for encapsulation. This encapsulation only emulates the TCP protocol header format without actually establishing a TCP connection, but can take full advantage of the TCP optimization capabilities of modern operating systems and network cards. In our tests TCP packet throughput can be improved several times, reaching performance levels close to those of the host network.

The STT tunnel is not pre-installed in the kernel and needs to be installed by compiling the OVS kernel module, which can be found in the previous section.

Enable STT tunnel:

The specific meaning of each field of the SecurityGroup can be found in the Kube-OVN API Reference.

Pods bind security-groups by adding annotations, two annotations are used.

  • port_security: source address verification. If this function is enabled, only packets with ip addresses assigned by kube-ovn ipam can be exported from the pod network adapter. After this function is disabled, any ip address can be exported
  • security_groups: indicates a security group that contains a series of ACL rules

In the inbound and outbound rules respectively, add a rule to allow access to the gateway, and set the rule to have the highest priority.

Deploying with the following yaml to bind security group, confirm that the Pod is operational:

apiVersion: v1\nkind: Pod\nmetadata:\n  labels:\n    app: static\n  annotations:\n    ovn.kubernetes.io/port_security: 'true'\n    ovn.kubernetes.io/security_groups: 'sg-gw-both'\n  name: sg-gw-both\n  namespace: default\nspec:\n  nodeName: kube-ovn-worker\n  containers:\n  - image: docker.io/library/nginx:alpine\n    imagePullPolicy: IfNotPresent\n    name: qatest\n

So for the use of security groups, be particularly clear about the effect of the added restriction rules. If it is simply to restrict traffic access, consider using a network policy instead.

Next, you can try ping a Pod IP in Cluster 1 directly from a Pod in Cluster 2 to see if you can work.

For a subnet that does not want to automatically publish routes to the other end, you can disable route broadcasting by modifying disableInterConnection in the Subnet spec.

For cases where there are overlapping CIDRs between clusters, and you only want to do partial subnet interconnection, you can manually publish subnet routing by following the steps below.

Create ovn-ic-config ConfigMap in kube-system Namespace, and set auto-route to false:

apiVersion: v1\nkind: ConfigMap\nmetadata:\n  name: ovn-ic-config\n  namespace: kube-system\ndata:\n  enable-ic: \"true\"\n  az-name: \"az1\" \n  ic-db-host: \"192.168.65.3\"\n  ic-nb-port: \"6645\" \n  ic-sb-port: \"6646\"\n  gw-nodes: \"az1-gw\"\n  auto-route: \"false\"\n

Find the address of the remote logical ports in each cluster separately, for later manual configuration of the route:

[root@az1 ~]# kubectl ko nbctl show\nswitch a391d3a1-14a0-4841-9836-4bd930c447fb (ts)\n    port ts-az1\n        type: router\n        router-port: az1-ts\n    port ts-az2\n        type: remote\n        addresses: [\"00:00:00:4B:E2:9F 169.254.100.31/24\"]\n\n[root@az2 ~]# kubectl ko nbctl show\nswitch da6138b8-de81-4908-abf9-b2224ec4edf3 (ts)\n    port ts-az2\n        type: router\n        router-port: az2-ts\n    port ts-az1\n        type: remote\n        addresses: [\"00:00:00:FB:2A:F7 169.254.100.79/24\"]        \n

The output above shows that the remote address from cluster az1 to cluster az2 is 169.254.100.31 and the remote address from az2 to az1 is 169.254.100.79.

In this example, the subnet CIDR within cluster az1 is 10.16.0.0/24 and the subnet CIDR within cluster az2 is 10.17.0.0/24.

Set up a route from cluster az1 to cluster az2 in cluster az1:

kubectl ko nbctl lr-route-add ovn-cluster 10.17.0.0/24 169.254.100.31\n

apiVersion: \"k8s.cni.cncf.io/v1\"\nkind: NetworkAttachmentDefinition\nmetadata:\n  name: lb-svc-attachment\n  namespace: kube-system\nspec:\n  config: '{\n      \"cniVersion\": \"0.3.0\",\n      \"type\": \"macvlan\",\n      \"master\": \"eth0\",                            //Physical network card, configure according to the actual situation\n      \"mode\": \"bridge\"\n    }'\n

By default, the physical NIC eth0 is used to implement the multi-interface functionality. If another physical NIC is needed, modify the master value to specify the name of the desired physical NIC.

"},{"location":"en/guide/loadbalancer-service/#create-subnet","title":"Create Subnet","text":"

The created Subnet is used to allocate LoadBalancerIP for the LoadBalancer Service, which should normally be accessible from outside the cluster. An Underlay Subnet can be configured for address allocation.

Refer to the following YAML to create a new subnet:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: attach-subnet\nspec:\n  protocol: IPv4\n  provider: lb-svc-attachment.kube-system          //The provider format is fixed and consists of the Name.Namespace of the net-attach-def resource created in the previous step\n  cidrBlock: 172.18.0.0/16\n  gateway: 172.18.0.1\n  excludeIps:\n  - 172.18.0.0..172.18.0.10\n

In the provider parameter of the Subnet, ovn or .ovn suffix is used to indicate that the subnet is managed by Kube-OVN and requires corresponding logical switch records to be created.

If provider is neither ovn nor ends with .ovn, Kube-OVN only provides the IPAM functionality to record IP address allocation without handling business logic for the subnet.

"},{"location":"en/guide/loadbalancer-service/#create-loadbalancer-service","title":"Create LoadBalancer Service","text":"

Refer to the following YAML to create a LoadBalancer Service:

apiVersion: v1\nkind: Service\nmetadata:\n   annotations:\n     lb-svc-attachment.kube-system.kubernetes.io/logical_switch: attach-subnet #Optional\n     ovn.kubernetes.io/attachmentprovider: lb-svc-attachment.kube-system #Required\n   labels:\n     app: dynamic\n   name: test-service\n   namespace: default\nspec:\n   loadBalancerIP: 172.18.0.18 #Optional\n   ports:\n     - name: test\n       protocol: TCP\n       port: 80\n       targetPort: 80\n   selector:\n     app: dynamic\n   sessionAffinity: None\n   type: LoadBalancer\n

In the yaml, the annotation ovn.kubernetes.io/attachmentprovider is required, and its value is composed of the Name.Namespace of the net-attach-def resource created in the first step. This annotation is used to find the net-attach-def resources when creating Pods.

The subnet used for multi-interface address allocation can be specified through an annotation. The annotation key format is net-attach-def resource's Name.Namespace.kubernetes.io/logical_switch. This configuration is optional and if LoadBalancerIP address is not specified, addresses will be dynamically allocated from this subnet and filled into the LoadBalancerIP field.

If a static LoadBalancerIP address is required, the spec.loadBalancerIP field can be configured. The address must be within the specified subnet's address range.

After creating the Service using the YAML, you can see the Pod startup information in the same namespace as the Service:

# kubectl get pod\nNAME READY STATUS RESTARTS AGE\nlb-svc-test-service-6869d98dd8-cjvll 1/1 Running 0 107m\n# kubectl get svc\nNAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE\ntest-service LoadBalancer 10.109.201.193 172.18.0.18 80:30056/TCP 107m\n

When specifying the service.spec.loadBalancerIP parameter, it will be assigned to the service's external IP field. If not specified, the parameter will be assigned a random value.

View the YAML output of the test Pod to see the assigned multi-interface addresses:

"},{"location":"en/guide/mirror/","title":"Traffic Mirror","text":"

The traffic mirroring feature allows packets to and from the container network to be copied to a specific NIC of the host. Administrators or developers can listen to this NIC to get the complete container network traffic for further analysis, monitoring, security auditing and other operations. It can also be integrated with traditional NPM for more fine-grained traffic visibility.

The traffic mirroring feature introduces some performance loss, with an additional CPU consumption of 5% to 10% depending on CPU performance and traffic characteristics.

"},{"location":"en/guide/mirror/#global-traffic-mirroring-settings","title":"Global Traffic Mirroring Settings","text":"

The traffic mirroring is disabled by default, please modify the args of kube-ovn-cni DaemonSet to enable it:

  • --enable-mirror=true: Whether to enable traffic mirroring.
  • --mirror-iface=mirror0: The name of the NIC that the traffic mirror is copied to. This NIC can be a physical NIC that already exists on the host machine. At this point the NIC will be bridged into the br-int bridge and the mirrored traffic will go directly to the underlying switch. If the NIC name does not exist, Kube-OVN will automatically create a virtual NIC with the same name, through which the administrator or developer can access all traffic on the current node on the host. The default is mirror0.

Next, you can listen to the traffic on mirror0 with tcpdump or other traffic analysis tools.

tcpdump -ni mirror0\n

"},{"location":"en/guide/networkpolicy-log/","title":"NetworkPolicy Logging","text":"

NetworkPolicy is a interface provided by Kubernetes and implemented by Kube-OVN through OVN's ACLs. With NetworkPolicy, if the networks are down, it is difficult to determine whether it is caused by a network failure or a NetworkPolicy rule problem. Kube-OVN provides NetworkPolicy logging to help administrators quickly locate whether a NetworkPolicy drop rule has been hit, and to record the illegal accesses.

Once NetworkPolicy logging is turned on, logs need to be printed for every packet that hits a Drop rule, which introduces additional performance overhead. Under a malicious attack, a large number of logs in a short period of time may exhaust the CPU. We recommend turning off logging by default in production environments and dynamically turning it on when you need to troubleshoot problems.

"},{"location":"en/guide/networkpolicy-log/#enable-networkpolicy-logging","title":"Enable NetworkPolicy Logging","text":"

Add the annotation ovn.kubernetes.io/enable_log to the NetworkPolicy where logging needs to be enabled, as follows:

Next, you can observe the log of dropped packets in /var/log/ovn/ovn-controller.log on the host of the corresponding Pod:

By default, Kube-OVN randomly assigns IPs and Macs based on the Subnet to which the Pod's Namespace belongs. For workloads that require fixed addresses, Kube-OVN provides multiple methods of fixing addresses depending on the scenario.

  • Single Pod fixed IP/Mac.
  • Workload IP Pool to specify fixed addresses.
  • StatefulSet fixed address.
  • KubeVirt VM fixed address.
"},{"location":"en/guide/static-ip-mac/#single-pod-fixed-ipmac","title":"Single Pod Fixed IP/Mac","text":"

You can specify the IP/Mac required for the Pod by annotation when creating the Pod. The kube-ovn-controller will skip the address random assignment phase and use the specified address directly after conflict detection, as follows:

apiVersion: apps/v1\nkind: Deployment\nmetadata:\n  name: ippool\n  labels:\n    app: ippool\nspec:\n  replicas: 2\n  selector:\n    matchLabels:\n      app: ippool\n  template:\n    metadata:\n      labels:\n        app: ippool\n      annotations:\n        ovn.kubernetes.io/ip_pool: 10.16.0.15,10.16.0.16,10.16.0.17 // for dualstack ippool use semicolon to separate addresses 10.16.0.15,fd00:10:16::000E;10.16.0.16,fd00:10:16::0\n    spec:\n      containers:\n        - name: ippool\n          image: docker.io/library/nginx:alpine\n

The following points need to be noted when using annotation.

  1. The IP/Mac used cannot conflict with an existing IP/Mac.
  2. The IP must be in the CIDR range of the Subnet it belongs to.
  3. You can specify only IP or Mac. When you specify only one, the other one will be assigned randomly.

  3. When the number of IPs in ovn.kubernetes.io/ip_pool is less than the number of replicas, the extra Pods will not be created. You need to adjust the number of IPs in ovn.kubernetes.io/ip_pool according to the update policy of the workload and the scaling plan.

StatefulSet supports fixed IP by default, and like other Workload, you can use ovn.kubernetes.io/ip_pool to specify the range of IP used by a Pod.

Since StatefulSet is mostly used for stateful services, which have higher requirements for fixed addresses, Kube-OVN has made special enhancements:

  1. Pods are assigned IPs in ovn.kubernetes.io/ip_pool in order. For example, if the name of the StatefulSet is web, web-0 will use the first IP in ovn.kubernetes.io/ip_pool, web-1 will use the second IP, and so on.
  2. The logical_switch_port in the OVN is not deleted during update or deletion of the StatefulSet Pod, and the newly generated Pod directly reuses the old logical port information. Pods can therefore reuse IP/Mac and other network information to achieve similar state retention as StatefulSet Volumes.
  3. Based on the capabilities of 2, for StatefulSet without the ovn.kubernetes.io/ip_pool annotation, a Pod is randomly assigned an IP/Mac when it is first generated, and then the network information remains fixed for the lifetime of the StatefulSet.

"},{"location":"en/guide/subnet/","title":"Config Subnet","text":"

Subnet is a core concept and basic unit of use in Kube-OVN, and Kube-OVN organizes IP and network configuration in terms of Subnet. Each Namespace can belong to a specific Subnet, and Pods under the Namespace automatically obtain IPs from the Subnet they belong to and share the network configuration (CIDR, gateway type, access control, NAT control, etc.).

Unlike other CNI implementations where each node is bound to a subnet, in Kube-OVN the Subnet is a global level virtual network configuration, and the addresses of one Subnet can be distributed on any node.

There are some differences in the usage and configuration of Overlay and Underlay Subnets, and this document will describe the common configurations and differentiated features of the different types of Subnets.

"},{"location":"en/guide/subnet/#default-subnet","title":"Default Subnet","text":"

To make it easier for users to get started quickly, Kube-OVN has a built-in default Subnet, all Namespaces that do not explicitly declare subnet affiliation are automatically assigned IPs from the default subnet and the network information. The configuration of this Subnet is specified at installation time, you can refer to Built-in Network Settings for more details. To change the CIDR of the default Subnet after installation please refer to Change Subnet CIDR.

In Overlay mode, the default Subnet uses a distributed gateway and NAT translation for outbound traffic, which behaves much the same as the Flannel's default behavior, allowing users to use most of the network features without additional configuration.

In Underlay mode, the default Subnet uses the physical gateway as the outgoing gateway and enables arping to check network connectivity.

In the Kubernetes network specification, it is required that Nodes can communicate directly with all Pods.

"},{"location":"en/guide/subnet/#overlay-subnet-gateway-settings","title":"Overlay Subnet Gateway Settings","text":"

This feature only works for Overlay mode Subnets, Underlay type Subnets need to use the underlying physical gateway to access the external network.

Pods under the Overlay Subnet need to access the external network through a gateway, and Kube-OVN currently supports two types of gateways: distributed gateway and centralized gateway which can be changed in the Subnet spec.

Both types of gateways support the natOutgoing setting, which allows the user to choose whether snat is required when the Pod accesses the external network.

"},{"location":"en/guide/subnet/#distributed-gateway","title":"Distributed Gateway","text":"

The default type of gateway for the Subnet, each node will act as a gateway for the pod on the current node to access the external network. The packets from container will flow into the host network stack from the local ovn0 NIC, and then forwarding the network according to the host's routing rules. When natOutgoing is true, the Pod will use the IP of the current host when accessing the external network.

Example of a Subnet, where the gatewayType field is distributed:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: distributed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: distributed\n  natOutgoing: true\n
"},{"location":"en/guide/subnet/#centralized-gateway","title":"Centralized Gateway","text":"

Note: Pods under a centralized subnet cannot be accessed through hostport or a NodePort type Service with externalTrafficPolicy: Local.

If you want traffic within the Subnet to access the external network using a fixed IP for security operations such as auditing and whitelisting, you can set the gateway type in the Subnet to centralized. In centralized gateway mode, packets from Pods accessing the external network are first routed to the ovn0 NIC of a specific nodes, and then outbound through the host's routing rules. When natOutgoing is true, the Pod will use the IP of a specific nodes when accessing the external network.

The centralized gateway example is as follows, where the gatewayType field is centralized and gatewayNode is the NodeName of the particular machine in Kubernetes.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: centralized\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: centralized\n  gatewayNode: \"node1,node2\"\n  natOutgoing: true\n
  • If a centralized gateway wants to specify a specific NIC of a machine for outbound networking, gatewayNode format can be changed to kube-ovn-worker:172.18.0.2, kube-ovn-control-plane:172.18.0.3.
  • The centralized gateway defaults to primary-backup mode, with only the primary node performing traffic forwarding. If you need to switch to ECMP mode, please refer to ECMP Settings.
  • The spec field enableEcmp has been added to the subnet crd definition since Kube-OVN v1.12.0 to migrate the ECMP switch to the subnet level. You can set whether to enable ECMP mode based on different subnets. The enable-ecmp parameter in the kube-ovn-controller deployment is no longer used. After the previous version is upgraded to v1.12.0, the subnet switch will automatically inherit the value of the original global switch parameter.
"},{"location":"en/guide/subnet/#subnet-acl","title":"Subnet ACL","text":"

For scenarios with fine-grained ACL control, Subnet of Kube-OVN provides ACL to enable fine-grained rules.

The ACL rules in Subnet are the same as the ACL rules in OVN, and you can refer to ovn-nb ACL Table for more details. The supported filed in match can refer to ovn-sb Logical Flow Table.

Example of an ACL rule that allows Pods with IP address 10.10.0.2 to access all addresses, but does not allow other addresses to access itself, is as follows:

The function of Subnet ACL can cover the function of Subnet isolation with better flexibility, we recommend using Subnet ACL to do the corresponding configuration.

By default the Subnets created by Kube-OVN can communicate with each other, and Pods can also access external networks through the gateway.

To control access between Subnets, set private to true in the subnet spec, and the Subnet will be isolated from other Subnets and external networks and can only communicate within the Subnet. If you want to open a whitelist, you can set it by allowSubnets. The CIDRs in allowSubnets can access the Subnet bidirectionally.

Kube-OVN supports multi-tenant isolation level VPC networks. Different VPC networks are independent of each other and can be configured separately with Subnet CIDRs, routing policies, security policies, outbound gateways, EIP, etc.

VPC is mainly used in scenarios where there requires strong isolation of multi-tenant networks and some Kubernetes networking features conflict under multi-tenant networks. For example, node and pod access, NodePort functionality, network access-based health checks, and DNS capabilities are not supported in multi-tenant network scenarios at this time. In order to facilitate common Kubernetes usage scenarios, Kube-OVN has a special design for the default VPC where the Subnet under the VPC can meet the Kubernetes specification. The custom VPC supports static routing, EIP and NAT gateways as described in this document. Common isolation requirements can be achieved through network policies and Subnet ACLs under the default VPC, so before using a custom VPC, please make sure whether you need VPC-level isolation and understand the limitations under the custom VPC.

The fundamental solution requires communication with Kylin and the corresponding network card manufacturer to update the system and drivers. A temporary solution would be to turn off tx offload on the physical NIC, but this would cause a significant degradation in tcp performance.

If the target of diagnose is specified as subnet, the script will create a daemonset on the subnet, and kube-ovn-pinger will detect the connectivity and network delay of all pods in this daemonset, and automatically destroy the daemonset after the test.

If the target of diagnose is specified as IPPorts, the script will let each kube-ovn-pinger pod detect whether the target protocol, IP, and Port are reachable.

As most of the nodes are damaged, the cluster needs to be rebuilt by recovering from one of the database files. If you have previously backed up the database you can use the previous backup file to restore it. If not you can use the following steps to generate a backup from an existing file.

Since the database file in the default folder is a cluster format database file containing information about the current cluster, you can't rebuild the database directly with this file, you need to use ovsdb-tool cluster-to-standalone to convert the format.

Select the first node in the ovn-central environment variable NODE_IPS to restore the database files. If the database file of the first node is corrupted, copy the file from the other machine /etc/origin/ovn to the first machine. Run the following command to generate a database file backup.

docker run -it -v /etc/origin/ovn:/etc/ovn kubeovn/kube-ovn:v1.12.12 bash\ncd /etc/ovn/\novsdb-tool cluster-to-standalone ovnnb_db_standalone.db ovnnb_db.db\novsdb-tool cluster-to-standalone ovnsb_db_standalone.db ovnsb_db.db\n

"},{"location":"en/reference/architecture/","title":"Architecture","text":"

This document describes the general architecture of Kube-OVN, the functionality of each component and how they interact with each other.

Overall, Kube-OVN serves as a bridge between Kubernetes and OVN, combining proven SDN with Cloud Native. This means that Kube-OVN not only implements network specifications under Kubernetes, such as CNI, Service and Networkpolicy, but also brings a large number of SDN domain capabilities to cloud-native, such as logical switches, logical routers, VPCs, gateways, QoS, ACLs and traffic mirroring.

Kube-OVN also maintains a good openness to integrate with many technology solutions, such as Cilium, Submariner, Prometheus, KubeVirt, etc.

"},{"location":"en/reference/architecture/#component-introduction","title":"Component Introduction","text":"

The components of Kube-OVN can be broadly divided into three categories.

  • Upstream OVN/OVS components.
  • Core Controller and Agent.
  • Monitoring, operation and maintenance tools and extension components.

"},{"location":"en/reference/architecture/#upstream-ovnovs-components","title":"Upstream OVN/OVS Components","text":"

This type of component comes from the OVN/OVS community with specific modifications for Kube-OVN usage scenarios. OVN/OVS itself is a mature SDN system for managing virtual machines and containers, and we strongly recommend that users interested in the Kube-OVN implementation read ovn-architecture(7) first to understand what OVN is and how to integrate with it. Kube-OVN uses the northbound interface of OVN to create and coordinate virtual networks and map the network concepts into Kubernetes.

All OVN/OVS-related components have been packaged into images and are ready to run in Kubernetes.

"},{"location":"en/reference/architecture/#ovn-central","title":"ovn-central","text":"

The ovn-central Deployment runs the control plane components of OVN, including ovn-nb, ovn-sb, and ovn-northd.

  • ovn-nb: Saves the virtual network configuration and provides an API for virtual network management. kube-ovn-controller will mainly interact with ovn-nb to configure the virtual network.
  • ovn-sb: Holds the logical flow table generated from the logical network of ovn-nb, as well as the actual physical network state of each node.
  • ovn-northd: translates the virtual network of ovn-nb into a logical flow table in ovn-sb.

Multiple instances of ovn-central will synchronize data via the Raft protocol to ensure high availability.

"},{"location":"en/reference/architecture/#ovs-ovn","title":"ovs-ovn","text":"

ovs-ovn runs as a DaemonSet on each node, with openvswitch, ovsdb, and ovn-controller running inside the Pod. These components act as agents for ovn-central to translate logical flow tables into real network configurations.

"},{"location":"en/reference/architecture/#core-controller-and-agent","title":"Core Controller and Agent","text":"

This part is the core component of Kube-OVN, serving as a bridge between OVN and Kubernetes, bridging the two systems and translating network concepts between them. Most of the core functions are implemented in these components.

"},{"location":"en/reference/architecture/#kube-ovn-controller","title":"kube-ovn-controller","text":"

This component performs the translation of all resources within Kubernetes to OVN resources and acts as the control plane for the entire Kube-OVN system. The kube-ovn-controller listens for events on all resources related to network functionality and updates the logical network within the OVN based on resource changes. The main resources listened including:

Pod\uff0cService\uff0cEndpoint\uff0cNode\uff0cNetworkPolicy\uff0cVPC\uff0cSubnet\uff0cVlan\uff0cProviderNetwork\u3002

Taking the Pod event as an example, kube-ovn-controller listens to the Pod creation event, allocates the address via the built-in in-memory IPAM function, and calls ovn-central to create logical ports, static routes and possible ACL rules. Next, kube-ovn-controller writes the assigned address and subnet information such as CIDR, gateway, route, etc. to the annotation of the Pod. This annotation is then read by kube-ovn-cni and used to configure the local network.

"},{"location":"en/reference/architecture/#kube-ovn-cni","title":"kube-ovn-cni","text":"

This component runs on each node as a DaemonSet, implements the CNI interface, and operates the local OVS to configure the local network.

This DaemonSet copies the kube-ovn binary to each machine as a tool for interaction between kubelet and kube-ovn-cni. This binary sends the corresponding CNI request to kube-ovn-cni for further operation. The binary will be copied to the /opt/cni/bin directory by default.

kube-ovn-cni will configure the specific network to perform the appropriate traffic operations, and the main tasks including:

  1. Config ovn-controller and vswitchd.
  2. Handle CNI Add/Del requests:
    1. Create or delete veth pair and bind or unbind to OVS ports.
    2. Configure OVS ports
    3. Update host iptables/ipset/route rules.
  3. Dynamically update the network QoS.
  4. Create and configure the ovn0 NIC to connect the container network and the host network.
  5. Configure the host NIC to implement Vlan/Underlay/EIP.
  6. Dynamically config inter-cluster gateways.
"},{"location":"en/reference/architecture/#monitoring-operation-and-maintenance-tools-and-extension-components","title":"Monitoring, Operation and Maintenance Tools and Extension Components","text":"

These components provide monitoring, diagnostics, operations tools, and external interface to extend the core network capabilities of Kube-OVN and simplify daily operations and maintenance.

Upstream OVN/OVS was originally designed with the goal of a general purpose SDN controller and data plane. Due to some specific usage of the Kubernetes network,Kube-OVN only focused on part of the features. In order to achieve better performance, stability and specific features, Kube-OVN has made some modifications to the upstream OVN/OVS. Users using their own OVN/OVS with Kube-OVN controllers need to be aware of the possible impact of the following changes:

"},{"location":"en/reference/tunnel-protocol/","title":"Tunnel Protocol Selection","text":"

Kube-OVN uses OVN/OVS as the data plane implementation and currently supports Geneve, Vxlan and STT tunnel encapsulation protocols. These three protocols differ in terms of functionality, performance and ease of use. This document will describe the differences in the use of the three protocols so that users can choose according to their situation.

"},{"location":"en/reference/tunnel-protocol/#geneve","title":"Geneve","text":"

The Geneve protocol is the default tunneling protocol selected during Kube-OVN deployment and is also the default recommended tunneling protocol for OVN. This protocol is widely supported in the kernel and can be accelerated using the generic offload capability of modern NICs. Since Geneve has a variable header, it is possible to use 24bit space to mark different datapaths users can create a larger number of virtual networks.

If you are using Mellanox or Corigine SmartNIC OVS offload, Geneve requires a higher kernel version. Upstream kernel of 5.4 or higher, or other compatible kernels that backports this feature.

Due to the use of UDP encapsulation, this protocol does not make good use of the TCP-related offloads of modern NICs when handling TCP over UDP, and consumes more CPU resources when handling large packets.

"},{"location":"en/reference/tunnel-protocol/#vxlan","title":"Vxlan","text":"

Vxlan is a recently supported protocol in the upstream OVN, which is widely supported in the kernel and can be accelerated using the common offload capabilities of modern NICs. Due to the limited length of the protocol header and the additional space required for OVN orchestration, there is a limit to the number of datapaths that can be created, with a maximum of 4096 datapaths and a maximum of 4096 ports under each datapath. Also, inport-based ACLs are not supported due to header length limitations.

Vxlan offloading is supported in common kernels if using Mellanox or Corigine SmartNIC.

Due to the use of UDP encapsulation, this protocol does not make good use of the TCP-related offloads of modern NICs when handling TCP over UDP, and consumes more CPU resources when handling large packets.

"},{"location":"en/reference/tunnel-protocol/#stt","title":"STT","text":"

The STT protocol is an early tunneling protocol supported by the OVN that uses TCP-like headers to take advantage of the TCP offload capabilities common to modern NICs and significantly increase TCP throughput. The protocol also has a long header to support full OVN capabilities and large-scale datapaths.

This protocol is not supported in the kernel. To use it, you need to compile an additional OVS kernel module and recompile the new version of the kernel module when upgrading the kernel.

This protocol is not currently supported by the SmartNic and cannot use the offloading capability of OVS offloading.

Kube-OVN configures load balancing for each Kubernetes Service on a logical switch on each subnet. When a Pod accesses other Pods by accessing the Service IP, a network packet is constructed with the Service IP as the destination address and the MAC address of the gateway as the destination MAC address. After the network packet enters the logical switch, load balancing will intercept and DNAT the network packet to modify the destination IP and port to the IP and port of one of the Endpoint corresponding to the Service. Since the logical switch does not modify the Layer 2 destination MAC address of the network packet, the network packet will still be delivered to the physic gateway after entering the physic switch, and the physic gateway will be required to forward the network packet.

By default, the default subnet uses Geneve to encapsulate cross-host traffic, and build an overlay network on top of the infrastructure.

For the case that you want the container network to use the physical network address directly, you can set the default subnet of Kube-OVN to work in Underlay mode, which can directly assign the address resources in the physical network to the containers, achieving better performance and connectivity with the physical network.

"},{"location":"en/start/underlay/#limitation","title":"Limitation","text":"

Since the container network in this mode uses physical network directly for L2 packet forwarding, L3 functions such as SNAT/EIP, distributed gateway/centralized gateway in Overlay mode cannot be used. VPC level isolation is also not available for underlay subnet.

"},{"location":"en/start/underlay/#comparison-with-macvlan","title":"Comparison with Macvlan","text":"

The Underlay mode of Kube-OVN is very similar to the Macvlan, with the following major differences in functionality and performance:

  1. Macvlan performs better in terms of throughput and latency performance metrics due to its shorter kernel path and the fact that it does not require OVS for packet processing.
  2. Kube-OVN provides arp-proxy functionality through flow tables to mitigate the risk of arp broadcast storms on large-scale networks.
  3. Since Macvlan works at the bottom of the kernel and bypasses the host netfilter, Service and NetworkPolicy functionality requires additional development. Kube-OVN provides Service and NetworkPolicy capabilities through the OVS flow table.
  4. Kube-OVN Underlay mode provides additional features such as address management, fixed IP and QoS compared to Macvlan.
"},{"location":"en/start/underlay/#environment-requirements","title":"Environment Requirements","text":"

In Underlay mode, the OVS will bridge a node NIC to the OVS bridge and send packets directly through that node NIC, relying on the underlying network devices for L2/L3 level forwarding capabilities. You need to configure the corresponding gateway, Vlan and security policy in the underlying network device in advance.

  1. For OpenStack VM environments, you need to turn off PortSecurity on the corresponding network port.
  2. For VMware vSwitch networks, MAC Address Changes, Forged Transmits and Promiscuous Mode Operation should be set to allow.
  3. For Hyper-V virtualization, MAC Address Spoofing should be enabled in VM nic advanced features.
  4. Public clouds, such as AWS, GCE, AliCloud, etc., do not support user-defined Mac, so they cannot support Underlay mode network. In this scenario, if you want to use Underlay, it is recommended to use the VPC-CNI provided by the corresponding public cloud vendor..
  5. The network interface that is bridged into ovs can not be type of Linux Bridge.

For management and container networks using the same NIC, Kube-OVN will transfer the NIC's Mac address, IP address, route, and MTU to the corresponding OVS Bridge to support single NIC deployment of Underlay networks. OVS Bridge name format is br-PROVIDER_NAME\uff0cPROVIDER_NAME is the name of ProviderNetwork (Default: provider).

ProviderNetwork provides the abstraction of host NIC to physical network mapping, unifies the management of NICs belonging to the same network, and solves the configuration problems in complex environments with multiple NICs on the same machine, inconsistent NIC names and inconsistent corresponding Underlay networks.

Create ProviderNetwork as below:

apiVersion: kubeovn.io/v1\nkind: ProviderNetwork\nmetadata:\n  name: net1\nspec:\n  defaultInterface: eth1\n  customInterfaces:\n    - interface: eth2\n      nodes:\n        - node1\n  excludeNodes:\n    - node2\n

Note: The length of the ProviderNetwork resource name must not exceed 12.

  • defaultInterface: The default node NIC name. When the ProviderNetwork is successfully created, an OVS bridge named br-net1 (in the format br-NAME) is created in each node (except excludeNodes) and the specified node NIC is bridged to this bridge.
  • customInterfaces: Optionally, you can specify the NIC to be used for a specific node.
  • excludeNodes: Optional, to specify nodes that do not bridge the NIC. Nodes in this list will be added with the net1.provider-network.ovn.kubernetes.io/exclude=true tag.

Other nodes will be added with the following tags:

Key Value Description net1.provider-network.ovn.kubernetes.io/ready true bridge work finished, ProviderNetwork is ready on this node net1.provider-network.ovn.kubernetes.io/interface eth1 The name of the bridged NIC in the node. net1.provider-network.ovn.kubernetes.io/mtu 1500 MTU of bridged NIC in node

If an IP has been configured on the node NIC, the IP address and the route on the NIC are transferred to the corresponding OVS bridge.

"},{"location":"en/start/underlay/#logical-gateway","title":"Logical Gateway","text":"

For cases where no gateway exists in the physical network, Kube-OVN supports the use of logical gateways configured in the subnet in Underlay mode. To use this feature, set spec.logicalGateway to true for the subnet:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n   name: subnet1\nspec:\n   protocol: IPv4\n   cidrBlock: 172.17.0.0/16\n   gateway: 172.17.0.1\n   vlan: vlan1\n   logicalGateway: true\n

When this feature is turned on, the Pod does not use an external gateway, but a Logical Router created by Kube-OVN to forward cross-subnet communication.

"},{"location":"en/start/underlay/#interconnection-of-underlay-and-overlay-networks","title":"Interconnection of Underlay and Overlay Networks","text":"

If a cluster has both Underlay and Overlay subnets, by default, Pods in the Overlay subnet can access the Pod IPs in the Underlay subnet via a gateway using NAT. From the perspective of Pods in the Underlay subnet, the addresses in the Overlay subnet are external, and require the underlying physical device to forward, but the underlying physical device does not know the addresses in the Overlay subnet and cannot forward. Therefore, Pods in the Underlay subnet cannot access Pods in the Overlay subnet directly via Pod IPs.

If you need to enable communication between Underlay and Overlay networks, you need to set the u2oInterconnection of the subnet to true. In this case, Kube-OVN will use an additional Underlay IP to connect the Underlay subnet and the ovn-cluster logical router, and set the corresponding routing rules to enable communication. Unlike the logical gateway, this solution only connects the Underlay and Overlay subnets within Kube-OVN, and other traffic accessing the Internet will still be forwarded through the physical gateway.

"},{"location":"en/start/underlay/#specify-logical-gateway-ip","title":"Specify logical gateway IP","text":"

After the interworking function is enabled, an IP from the subnet will be randomly selected as the logical gateway. If you need to specify the logical gateway of the Underlay Subnet, you can specify the field u2oInterconnectionIP.

"},{"location":"en/start/underlay/#specify-custom-vpc-for-underlay-subnet-connection","title":"Specify custom VPC for Underlay Subnet connection","text":"

By default, the Underlay Subnet will communicate with the Overlay Subnet on the default VPC. If you want to specify to communicate with a certain VPC, after setting u2oInterconnection to true, specify the subnet.spec.vpc field as the name of the VPC.

"},{"location":"en/start/underlay/#notice","title":"Notice","text":"

If you have an IP address configured on the network card of the node you are using, and the operating system configures the network using Netplan (such as Ubuntu), it is recommended that you set the renderer of Netplan to NetworkManager and configure a static IP address for the node's network card (disable DHCP).

network:\n  renderer: NetworkManager\n  ethernets:\n    eth0:\n      dhcp4: no\n      addresses:\n        - 172.16.143.129/24\n  version: 2\n

If you want to modify the IP or routing configuration of the network card, you need to execute the following commands after modifying the Netplan configuration:

netplan generate\n\nnmcli connection reload netplan-eth0\nnmcli device set eth0 managed yes\n

After executing the above commands, Kube-OVN will transfer the IP and routing from the network card to the OVS bridge.

If your operating system manages the network using NetworkManager (such as CentOS), you need to execute the following command after modifying the network card configuration:

nmcli connection reload eth0\nnmcli device set eth0 managed yes\nnmcli -t -f GENERAL.STATE device show eth0 | grep -qw unmanaged || nmcli device reapply eth0\n

Notice\uff1aIf the host nic's MAC is changed, Kube-OVN will not change the OVS bridge's MAC unless kube-ovn-cni is restarted.

When physical networks enable hairpin or similar behaviors, problems such as gateway check failure when creating Pods and abnormal network communication of Pods may occur. This is because the default MAC learning function of OVS bridge does not support this kind of network environment.

At some edge and 5G scenarios, there will be a lot of TCP communication between Pods on the same node. By using the open source istio-tcpip-bypass project from Intel, Pods can use the ability of eBPF to bypass the host's TCP/IP protocol stack and communicate directly through sockets, thereby greatly reducing latency and improving throughput.

"},{"location":"en/advance/accelerate-intra-node-tcp-with-ebpf/#basic-principle","title":"Basic Principle","text":"

At present, two Pods on the same host need to go through a lot of network stacks, including TCP/IP, netfilter, OVS, etc., as shown in the following figure:

istio-tcpip-bypass plugin can automatically analyze and identify TCP communication within the same host, and bypass the complex kernel stack so that socket data transmission can be performed directly to reduce network stack processing overhead, as shown in the following figure:

Due to the fact that this component can automatically identify TCP communication within the same host and optimize it. In the Service Mesh environment based on the proxy mode, this component can also enhance the performance of Service Mesh.

eBPF requires a kernel version of at least 5.4.0-74-generic. It is recommended to use Ubuntu 20.04 and Linux 5.4.0-74-generic kernel version for testing.

Deploy two performance test Pods on the same node. If there are multiple machines in the cluster, you need to specify nodeSelector:

Deploy the istio-tcpip-bypass plugin:

kubectl apply -f https://raw.githubusercontent.com/intel/istio-tcpip-bypass/main/bypass-tcpip-daemonset.yaml\n

Enter the perf client container again for performance testing:

According to the test results, the TCP latency will decrease by 40% ~ 60% under different packet sizes, and the throughput will increase by 40% ~ 80% when the packet size is greater than 1024 bytes.

Packet Size (byte) eBPF tcp_lat (us) Default tcp_lat (us) eBPF tcp_bw (Mb/s) Default tcp_bw(Mb/s) 1 20.2 44.5 1.36 4.27 4 20.2 48.7 5.48 16.7 16 19.6 41.6 21.7 63.5 64 18.8 41.3 96.8 201 256 19.2 36 395 539 1024 18.3 42.4 1360 846 4096 16.5 62.6 4460 2430 16384 20.2 58.8 9600 6900

In the hardware environment under test, when the packet size is less than 512 bytes, the throughput indicator optimized by eBPF is lower than the throughput under the default configuration. This situation may be related to the TCP aggregation optimization of the network card under the default configuration. If the application scenario is sensitive to small packet throughput, you need to test in the corresponding environment Determine whether to enable eBPF optimization. We will also optimize the throughput of eBPF TCP small packet scenarios in the future.

After deploying Hubble Relay, Hubble can provide complete cluster-wide network traffic observation.

"},{"location":"en/advance/cilium-hubble-observe/#configure-port-forwarding","title":"Configure port forwarding","text":"

In order to access the Hubble API normally, you need to create a port forwarding to forward the local request to the Hubble Service. You can execute the kubectl port-forward deployment/hubble-relay -n kube-system 4245:4245 command to open the port forwarding in the current terminal.

The port forwarding configuration can refer to Port Forwarding.

kubectl port-forward is a blocking command, you can open a new terminal to execute the following command to observe the traffic information.

After configuring the port forwarding, execute the hubble status command in the terminal. If there is an output similar to the following, the port forwarding configuration is correct, and you can use the command line to observe the traffic.

# hubble status\nHealthcheck (via localhost:4245): Ok\nCurrent/Max Flows: 8,190/8,190 (100.00%)\nFlows/s: 22.86\nConnected Nodes: 2/2\n

Execute the hubble observe command in the terminal to view the traffic information of the cluster.

The traffic observed by the cilium-test namespace is as follows:

Pay attention to the hubble observe command display result, which is the traffic information queried when the current command line is executed. Executing the command line multiple times can view different traffic information. For more detailed observation information, you can execute the hubble help observe command to view the detailed usage of Hubble CLI.

Execute the cilium status command to confirm that the Hubble UI has been successfully installed. In the second step of the Hubble installation, the installation of the UI has been supplemented.

Execute the command cilium hubble ui to automatically create port forwarding and map the hubble-ui service to the local port.

When the command is executed normally, the local browser will be automatically opened and jump to the Hubble UI interface. If it does not jump automatically, enter http://localhost:12000 in the browser to open the UI observation interface.

On the top left of the UI, select the cilium-test namespace to view the test traffic information provided by Cilium.

Look at the Cilium official document explanation, the CiliumNetworkPolicy resource limits the control at the namespace level. For more information, please refer to Cilium Limitations.

If there is a network policy rule match, only the Pod in the same namespace can access according to the rule, and the Pod in the other namespace is denied access by default.

If you want to implement cross-namespace access, you need to specify the namespace information in the rule.

Refer to the document, modify the CiliumNetworkPolicy resource, and add namespace information:

  ingress:\n  - fromEndpoints:\n    - matchLabels:\n        app: dynamic\n        k8s:io.kubernetes.pod.namespace: default    // control the Pod access in other namespace\n

Look at the modified CiliumNetworkPolicy resource information:

# kubectl get cnp -n test  -o yaml l3-rule\napiVersion: cilium.io/v2\nkind: CiliumNetworkPolicy\nmetadata:\n  name: l3-rule\n  namespace: test\nspec:\n  endpointSelector:\n    matchLabels:\n      app: test\n  ingress:\n  - fromEndpoints:\n    - matchLabels:\n        app: dynamic\n    - matchLabels:\n        app: dynamic\n        k8s:io.kubernetes.pod.namespace: default\n

Test the Pod access in the default namespace again, and the destination Pod access is normal:

# kubectl exec -it dynamic-7d8d7874f5-9v5c4 -n test -- bash\nbash-5.0# ping -c 3 10.16.0.41\nPING 10.16.0.41 (10.16.0.41): 56 data bytes\n64 bytes from 10.16.0.41: seq=0 ttl=64 time=2.383 ms\n64 bytes from 10.16.0.41: seq=1 ttl=64 time=0.115 ms\n64 bytes from 10.16.0.41: seq=2 ttl=64 time=0.142 ms\n\n--- 10.16.0.41 ping statistics ---\n3 packets transmitted, 3 packets received, 0% packet loss\nround-trip min/avg/max = 0.115/0.880/2.383 ms\n

Using the standard Kubernetes network policy networkpolicy, the test results show that Cilium also restricts access within the same namespace, and cross-namespace access is prohibited.

It is different from Kube-OVN implementation. Kube-OVN supports standard k8s network policy, which restricts the destination Pod in a specific namespace, but there is no namespace restriction on the source Pod. Any Pod that meets the restriction rules in any namespace can access the destination Pod.

After the network policy takes effect, cross-namespace access is still prohibited, which is consistent with the L3 network policy test results.

After the L4 network policy takes effect, ping cannot be used, but TCP access that meets the policy rules can be executed normally.

Now Kube-OVN extend the subnet to integrate with other different network plugins, so that other network plugins can also use the IPAM functionality of Kube-OVN.

"},{"location":"en/advance/multi-nic/#workflow","title":"Workflow","text":"

The above diagram shows how to manage the IP addresses of other network plugins via Kube-OVN. The eth0 NIC of the container is connected to the OVN network and the net1 NIC is connected to other CNI networks. The network definition for the net1 network is taken from the NetworkAttachmentDefinition resource definition in multus-cni.

When a Pod is created, kube-ovn-controller will get the Pod add event, find the corresponding Subnet according to the annotation in the Pod, then manage the address from it, and write the address information assigned to the Pod back to the Pod annotation.

The CNI on the container machine can configure kube-ovn-cni as the ipam plugin. kube-ovn-cni will read the Pod annotation and return the address information to the corresponding CNI plugin using the standard format of the CNI protocol.

In the Overlay Subnet under the default VPC, when the natOutgoing switch is turned on, all Pods in the subnet need to do SNAT to access the external network, but in some scenarios we do not want all Pods in the subnet to access the external network by SNAT.

So the NAT Policy Rule is to provide a way for users to decide which CIDRs or IPs in the subnet to access the external network need SNAT.

"},{"location":"en/advance/nat-policy-rule/#how-to-use-nat-policy-rules","title":"How to use NAT Policy Rules","text":"

Enable the natOutgoing switch in subnet.Spec, and add the field natOutgoingPolicyRules as follows:

spec:\n  natOutgoing: true\n  natOutgoingPolicyRules:\n    - action: forward\n      match:\n        srcIPs: 10.0.11.0/30,10.0.11.254\n    - action: nat\n      match:\n        srcIPs: 10.0.11.128/26\n        dstIPs: 114.114.114.114,8.8.8.8\n

The above case shows that there are two NAT policy rules:

  1. Packets with source IP 10.0.11.0/30 or 10.0.11.254 will not perform SNAT when accessing the external network.
  2. When a packet with source IP 10.0.11.128/26 and destination IP 114.114.114.114 or 8.8.8.8 accesses the external network, SNAT will be performed.

Field description:

action: The action that will be executed for packets that meets the corresponding conditions of the match. The action is divided into two types: forward and nat. When natOutgoingPolicyRules is not configured, packets are still SNAT by default.

match: Indicates the matching segment of the message, the matching segment includes srcIPs and dstIPs, here indicates the source IP and destination IP of the message from the subnet to the external network. match.srcIPs and match.dstIPs support multiple cidr and ip, separated by commas. If multiple match rules overlap, the action that is matched first will be executed according to the order of the natOutgoingPolicyRules array.

The reason for this step is to let the Pod regenerate /etc/resolv.conf so that the nameserver points to the local DNS IP.

Kube-OVN uses OVS for traffic forwarding in the final data plane, and the associated flow table matching, tunnel encapsulation and other functions are CPU-intensive, which consumes a lot of CPU resources and leads to higher latency and lower throughput under heavy traffic. Mellanox Accelerated Switching And Packet Processing (ASAP\u00b2) technology offloads OVS-related operations to an eSwitch within the eSwitch in the hardware. This technology can shorten the data path without modifying the OVS control plane, avoiding the use of host CPU resources, which dramatically reduce latency and significantly increase the throughput.

In some scenarios, the network environment does not support Underlay mode, but still need Pods and external devices directly access through IP, then you can use the routing method to connect the container network and the external.

Only Overlay Subnets in default VPC support this method. In this case, the Pod IP goes directly to the underlying network, which needs to disable IP checks for source and destination addresses.

"},{"location":"en/advance/overlay-with-route/#prerequisites","title":"Prerequisites","text":"
  • In this mode, the host needs to open the ip_forward.
  • Check if there is a Drop rule in the forward chain in the host iptables that should be modified for container-related traffic.
  • Due to the possibility of asymmetric routing, the host needs to allow packets with a ct status of INVALID.
"},{"location":"en/advance/overlay-with-route/#steps","title":"Steps","text":"

For subnets that require direct external routing, you need to set natOutgoing of the subnet to false to turn off nat mapping and make the Pod IP directly accessible to the external network.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: routed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: distributed\n  natOutgoing: false\n

At this point, the Pod's packets can reach the peer node via the host route, but the peer node does not yet know where the return packets should be sent to and needs to add a return route.

If the peer host and the container host are on the same Layer 2 network, we can add a static route directly to the peer host to point the next hop of the container network to any machine in the Kubernetes cluster.

ip route add 10.166.0.0/16 via 192.168.2.10 dev eth0\n

10.166.0.0/16 is the container subnet CIDR, and 192.168.2.10 is one node in the Kubernetes cluster.

If the peer host and the container host are not in the same layer 2 network, you need to configure the corresponding rules on the router.

Note: Specifying an IP for a single node may lead to single point of failure. To achieve fast failover, Keepalived can be used to set up a VIP for multiple nodes, and the next hop of the route can be directed to the VIP.

In some virtualized environments, the virtual network identifies asymmetric traffic as illegal traffic and drops it. In this case, you need to adjust the gatewayType of the Subnet to centralized and set the next hop to the IP of the gatewayNode node during route setup.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: routed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: centralized\n  gatewayNode: \"node1\"\n  natOutgoing: false\n

After the establishment is complete, you can capture packets and observe that the packets have been encrypted:

# tcpdump -i eth0 -nel esp\n10:01:40.349896 IP kube-ovn-worker > kube-ovn-control-plane.kind: ESP(spi=0xcc91322a,seq=0x13d0), length 156\n10:01:40.350015 IP kube-ovn-control-plane.kind > kube-ovn-worker: ESP(spi=0xc8df4221,seq=0x1d37), length 156\n

After executing the script, you can turn off IPsec by executing the command:

# bash ipsec.sh stop\n

Or execute the command to open it again:

# bash ipsec.sh start\n

This functions basically the same as ovn-eip-fip-snat.md .

As for the different parts, which will be specified in the following sections, mainly including the creation of ovn-eip of lsp type and the automatic maintenance of bfd as well as ecmp static routes based on vpc enable_bfd.

The above section is exactly the same with ovn-eip-fip-snat.md.

After these functions are verified, the vpc can be switched directly to the ecmp-based bfd static route based on the following way, or of course, switched directly back.

Before customizing vpc to use this feature, you need to provide some gateway nodes, at least 2. Note that the name of the current implementation of ovn-eip must be consistent with the gateway node name, no automated maintenance is currently done for this resource.

# cat gw-node-eip.yaml\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-1\nspec:\n  externalSubnet: external204\n  type: lsp\n\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-2\nspec:\n  externalSubnet: external204\n  type: lsp\n\n---\nkind: OvnEip\napiVersion: kubeovn.io/v1\nmetadata:\n  name: pc-node-3\nspec:\n  externalSubnet: external204\n  type: lsp\n

Since this scenario is currently designed for vpc ecmp out of the public network, the gateway node above will not trigger the creation of a gateway NIC when there is no vpc enabled bfd, i.e. when there is no ovn eip (lrp) with enable bfd labeled, and will not be able to successfully start listening to the bfd session on the other side.

note:

  1. Customize ecmp under vpc to use only static ecmp bfd routes. vpc enableBfd and subnet enableEcmp will only take effect if they are enabled at the same time, before static ecmp bfd routes are automatically managed.
  2. If the above configuration is turned off, it will automatically switch back to the regular default static route.
  3. This feature is not available for the default vpc, only custom vpc is supported, the default vpc has more complex policy routing.
  4. The enableEcmp of the subnet of the custom vpc uses only static routes, the gateway type gatewayType has no effect.
  5. When EnableExternal is turned off in vpc, the external network cannot be passed inside vpc.
  6. When EnableExternal is enabled on vpc, when EnableBfd is turned off, it will be based on the normal default route to the external network and will not have high availability.

In some cases the container network outperforms the host network, this is because the container network path is optimized to completely bypass netfilter. Due to the existence of kube-proxy, all packets in host network have to go through netfilter, which will lead to more CPU consumption, so that container network in some environments has better performance.

The L2 LB implementation of OVN requires calling the kernel's conntrack module and recirculate, resulting in a significant CPU overhead, which is tested to be around 20%.

Since the container network and the host network are on different network ns, the packets will pass through the netfilter module several times when they are transmitted across the host, which results in a CPU overhead of nearly 20%. The FastPath module can reduce CPU overhead by bypassing netfilter, since in most cases applications within a container network do not need to use the functionality of the netfilter module.

If you need to use the functions provided by netfilter such as iptables, ipvs, nftables, etc. in the container network, this module will disable the related functions.

Since kernel modules are kernel version dependent, it is not possible to provide a single kernel module artifact that adapts to all kernels. We pre-compiled the FastPath module for part of the kernels, which can be accessed by tunning-package.

You can also compile it manually, see Compiling FastPath Module

After obtaining the kernel module, you can load the FastPath module on each node using insmod kube_ovn_fastpath.ko and verify that the module was loaded successfully using dmesg:

OVS flow processing including hashing, matching, etc. consumes about 10% of the CPU resources.

It has been tested that the CPU consumption of flow-related operations is reduced to about 5% when the corresponding instruction set optimizations are enabled.

Similar to the compilation of the FastPath module, it is not possible to provide a single kernel module artifact for all kernels. Users need to compile manually or go to tunning-package to see if a compiled package is available for download.

"},{"location":"en/advance/performance-tuning/#using-stt-type-tunnel","title":"Using STT Type Tunnel","text":"

Common tunnel encapsulation protocols such as Geneve and Vxlan use the UDP protocol to encapsulate packets and are well supported in the kernel. However, when TCP packets are encapsulated using UDP, the optimization and offload features of modern operating systems and network cards for the TCP protocol do not work well, resulting in a significant drop in TCP throughput. In some virtualization scenarios, due to CPU limitations, TCP packet throughput may even be a tenth of that of the host network.

STT provides an innovative tunneling protocol that uses TCP formatted header for encapsulation. This encapsulation only emulates the TCP protocol header format without actually establishing a TCP connection, but can take full advantage of the TCP optimization capabilities of modern operating systems and network cards. In our tests TCP packet throughput can be improved several times, reaching performance levels close to those of the host network.

The STT tunnel is not pre-installed in the kernel and needs to be installed by compiling the OVS kernel module, which can be found in the previous section.

Enable STT tunnel:

The specific meaning of each field of the SecurityGroup can be found in the Kube-OVN API Reference.

Pods bind security-groups by adding annotations, two annotations are used.

  • port_security: source address verification. If this function is enabled, only packets with ip addresses assigned by kube-ovn ipam can be exported from the pod network adapter. After this function is disabled, any ip address can be exported
  • security_groups: indicates a security group that contains a series of ACL rules

In the inbound and outbound rules respectively, add a rule to allow access to the gateway, and set the rule to have the highest priority.

Deploying with the following yaml to bind security group, confirm that the Pod is operational:

apiVersion: v1\nkind: Pod\nmetadata:\n  labels:\n    app: static\n  annotations:\n    ovn.kubernetes.io/port_security: 'true'\n    ovn.kubernetes.io/security_groups: 'sg-gw-both'\n  name: sg-gw-both\n  namespace: default\nspec:\n  nodeName: kube-ovn-worker\n  containers:\n  - image: docker.io/library/nginx:alpine\n    imagePullPolicy: IfNotPresent\n    name: qatest\n

So for the use of security groups, be particularly clear about the effect of the added restriction rules. If it is simply to restrict traffic access, consider using a network policy instead.

Next, you can try ping a Pod IP in Cluster 1 directly from a Pod in Cluster 2 to see if you can work.

For a subnet that does not want to automatically publish routes to the other end, you can disable route broadcasting by modifying disableInterConnection in the Subnet spec.

For cases where there are overlapping CIDRs between clusters, and you only want to do partial subnet interconnection, you can manually publish subnet routing by following the steps below.

Create ovn-ic-config ConfigMap in kube-system Namespace, and set auto-route to false:

apiVersion: v1\nkind: ConfigMap\nmetadata:\n  name: ovn-ic-config\n  namespace: kube-system\ndata:\n  enable-ic: \"true\"\n  az-name: \"az1\" \n  ic-db-host: \"192.168.65.3\"\n  ic-nb-port: \"6645\" \n  ic-sb-port: \"6646\"\n  gw-nodes: \"az1-gw\"\n  auto-route: \"false\"\n

Find the address of the remote logical ports in each cluster separately, for later manual configuration of the route:

[root@az1 ~]# kubectl ko nbctl show\nswitch a391d3a1-14a0-4841-9836-4bd930c447fb (ts)\n    port ts-az1\n        type: router\n        router-port: az1-ts\n    port ts-az2\n        type: remote\n        addresses: [\"00:00:00:4B:E2:9F 169.254.100.31/24\"]\n\n[root@az2 ~]# kubectl ko nbctl show\nswitch da6138b8-de81-4908-abf9-b2224ec4edf3 (ts)\n    port ts-az2\n        type: router\n        router-port: az2-ts\n    port ts-az1\n        type: remote\n        addresses: [\"00:00:00:FB:2A:F7 169.254.100.79/24\"]        \n

The output above shows that the remote address from cluster az1 to cluster az2 is 169.254.100.31 and the remote address from az2 to az1 is 169.254.100.79.

In this example, the subnet CIDR within cluster az1 is 10.16.0.0/24 and the subnet CIDR within cluster az2 is 10.17.0.0/24.

Set up a route from cluster az1 to cluster az2 in cluster az1:

kubectl ko nbctl lr-route-add ovn-cluster 10.17.0.0/24 169.254.100.31\n

apiVersion: \"k8s.cni.cncf.io/v1\"\nkind: NetworkAttachmentDefinition\nmetadata:\n  name: lb-svc-attachment\n  namespace: kube-system\nspec:\n  config: '{\n      \"cniVersion\": \"0.3.0\",\n      \"type\": \"macvlan\",\n      \"master\": \"eth0\",                            //Physical network card, configure according to the actual situation\n      \"mode\": \"bridge\"\n    }'\n

By default, the physical NIC eth0 is used to implement the multi-interface functionality. If another physical NIC is needed, modify the master value to specify the name of the desired physical NIC.

"},{"location":"en/guide/loadbalancer-service/#create-subnet","title":"Create Subnet","text":"

The created Subnet is used to allocate LoadBalancerIP for the LoadBalancer Service, which should normally be accessible from outside the cluster. An Underlay Subnet can be configured for address allocation.

Refer to the following YAML to create a new subnet:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: attach-subnet\nspec:\n  protocol: IPv4\n  provider: lb-svc-attachment.kube-system          //The provider format is fixed and consists of the Name.Namespace of the net-attach-def resource created in the previous step\n  cidrBlock: 172.18.0.0/16\n  gateway: 172.18.0.1\n  excludeIps:\n  - 172.18.0.0..172.18.0.10\n

In the provider parameter of the Subnet, ovn or .ovn suffix is used to indicate that the subnet is managed by Kube-OVN and requires corresponding logical switch records to be created.

If provider is neither ovn nor ends with .ovn, Kube-OVN only provides the IPAM functionality to record IP address allocation without handling business logic for the subnet.

"},{"location":"en/guide/loadbalancer-service/#create-loadbalancer-service","title":"Create LoadBalancer Service","text":"

Refer to the following YAML to create a LoadBalancer Service:

apiVersion: v1\nkind: Service\nmetadata:\n   annotations:\n     lb-svc-attachment.kube-system.kubernetes.io/logical_switch: attach-subnet #Optional\n     ovn.kubernetes.io/attachmentprovider: lb-svc-attachment.kube-system #Required\n   labels:\n     app: dynamic\n   name: test-service\n   namespace: default\nspec:\n   loadBalancerIP: 172.18.0.18 #Optional\n   ports:\n     - name: test\n       protocol: TCP\n       port: 80\n       targetPort: 80\n   selector:\n     app: dynamic\n   sessionAffinity: None\n   type: LoadBalancer\n

In the yaml, the annotation ovn.kubernetes.io/attachmentprovider is required, and its value is composed of the Name.Namespace of the net-attach-def resource created in the first step. This annotation is used to find the net-attach-def resources when creating Pods.

The subnet used for multi-interface address allocation can be specified through an annotation. The annotation key format is net-attach-def resource's Name.Namespace.kubernetes.io/logical_switch. This configuration is optional and if LoadBalancerIP address is not specified, addresses will be dynamically allocated from this subnet and filled into the LoadBalancerIP field.

If a static LoadBalancerIP address is required, the spec.loadBalancerIP field can be configured. The address must be within the specified subnet's address range.

After creating the Service using the YAML, you can see the Pod startup information in the same namespace as the Service:

# kubectl get pod\nNAME READY STATUS RESTARTS AGE\nlb-svc-test-service-6869d98dd8-cjvll 1/1 Running 0 107m\n# kubectl get svc\nNAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE\ntest-service LoadBalancer 10.109.201.193 172.18.0.18 80:30056/TCP 107m\n

When specifying the service.spec.loadBalancerIP parameter, it will be assigned to the service's external IP field. If not specified, the parameter will be assigned a random value.

View the YAML output of the test Pod to see the assigned multi-interface addresses:

"},{"location":"en/guide/mirror/","title":"Traffic Mirror","text":"

The traffic mirroring feature allows packets to and from the container network to be copied to a specific NIC of the host. Administrators or developers can listen to this NIC to get the complete container network traffic for further analysis, monitoring, security auditing and other operations. It can also be integrated with traditional NPM for more fine-grained traffic visibility.

The traffic mirroring feature introduces some performance loss, with an additional CPU consumption of 5% to 10% depending on CPU performance and traffic characteristics.

"},{"location":"en/guide/mirror/#global-traffic-mirroring-settings","title":"Global Traffic Mirroring Settings","text":"

The traffic mirroring is disabled by default, please modify the args of kube-ovn-cni DaemonSet to enable it:

  • --enable-mirror=true: Whether to enable traffic mirroring.
  • --mirror-iface=mirror0: The name of the NIC that the traffic mirror is copied to. This NIC can be a physical NIC that already exists on the host machine. At this point the NIC will be bridged into the br-int bridge and the mirrored traffic will go directly to the underlying switch. If the NIC name does not exist, Kube-OVN will automatically create a virtual NIC with the same name, through which the administrator or developer can access all traffic on the current node on the host. The default is mirror0.

Next, you can listen to the traffic on mirror0 with tcpdump or other traffic analysis tools.

tcpdump -ni mirror0\n

"},{"location":"en/guide/networkpolicy-log/","title":"NetworkPolicy Logging","text":"

NetworkPolicy is a interface provided by Kubernetes and implemented by Kube-OVN through OVN's ACLs. With NetworkPolicy, if the networks are down, it is difficult to determine whether it is caused by a network failure or a NetworkPolicy rule problem. Kube-OVN provides NetworkPolicy logging to help administrators quickly locate whether a NetworkPolicy drop rule has been hit, and to record the illegal accesses.

Once NetworkPolicy logging is turned on, logs need to be printed for every packet that hits a Drop rule, which introduces additional performance overhead. Under a malicious attack, a large number of logs in a short period of time may exhaust the CPU. We recommend turning off logging by default in production environments and dynamically turning it on when you need to troubleshoot problems.

"},{"location":"en/guide/networkpolicy-log/#enable-networkpolicy-logging","title":"Enable NetworkPolicy Logging","text":"

Add the annotation ovn.kubernetes.io/enable_log to the NetworkPolicy where logging needs to be enabled, as follows:

Next, you can observe the log of dropped packets in /var/log/ovn/ovn-controller.log on the host of the corresponding Pod:

By default, Kube-OVN randomly assigns IPs and Macs based on the Subnet to which the Pod's Namespace belongs. For workloads that require fixed addresses, Kube-OVN provides multiple methods of fixing addresses depending on the scenario.

  • Single Pod fixed IP/Mac.
  • Workload IP Pool to specify fixed addresses.
  • StatefulSet fixed address.
  • KubeVirt VM fixed address.
"},{"location":"en/guide/static-ip-mac/#single-pod-fixed-ipmac","title":"Single Pod Fixed IP/Mac","text":"

You can specify the IP/Mac required for the Pod by annotation when creating the Pod. The kube-ovn-controller will skip the address random assignment phase and use the specified address directly after conflict detection, as follows:

apiVersion: apps/v1\nkind: Deployment\nmetadata:\n  name: ippool\n  labels:\n    app: ippool\nspec:\n  replicas: 2\n  selector:\n    matchLabels:\n      app: ippool\n  template:\n    metadata:\n      labels:\n        app: ippool\n      annotations:\n        ovn.kubernetes.io/ip_pool: 10.16.0.15,10.16.0.16,10.16.0.17 // for dualstack ippool use semicolon to separate addresses 10.16.0.15,fd00:10:16::000E;10.16.0.16,fd00:10:16::0\n    spec:\n      containers:\n        - name: ippool\n          image: docker.io/library/nginx:alpine\n

The following points need to be noted when using annotation.

  1. The IP/Mac used cannot conflict with an existing IP/Mac.
  2. The IP must be in the CIDR range of the Subnet it belongs to.
  3. You can specify only IP or Mac. When you specify only one, the other one will be assigned randomly.

  3. When the number of IPs in ovn.kubernetes.io/ip_pool is less than the number of replicas, the extra Pods will not be created. You need to adjust the number of IPs in ovn.kubernetes.io/ip_pool according to the update policy of the workload and the scaling plan.

StatefulSet supports fixed IP by default, and like other Workload, you can use ovn.kubernetes.io/ip_pool to specify the range of IP used by a Pod.

Since StatefulSet is mostly used for stateful services, which have higher requirements for fixed addresses, Kube-OVN has made special enhancements:

  1. Pods are assigned IPs in ovn.kubernetes.io/ip_pool in order. For example, if the name of the StatefulSet is web, web-0 will use the first IP in ovn.kubernetes.io/ip_pool, web-1 will use the second IP, and so on.
  2. The logical_switch_port in the OVN is not deleted during update or deletion of the StatefulSet Pod, and the newly generated Pod directly reuses the old logical port information. Pods can therefore reuse IP/Mac and other network information to achieve similar state retention as StatefulSet Volumes.
  3. Based on the capabilities of 2, for StatefulSet without the ovn.kubernetes.io/ip_pool annotation, a Pod is randomly assigned an IP/Mac when it is first generated, and then the network information remains fixed for the lifetime of the StatefulSet.

"},{"location":"en/guide/subnet/","title":"Config Subnet","text":"

Subnet is a core concept and basic unit of use in Kube-OVN, and Kube-OVN organizes IP and network configuration in terms of Subnet. Each Namespace can belong to a specific Subnet, and Pods under the Namespace automatically obtain IPs from the Subnet they belong to and share the network configuration (CIDR, gateway type, access control, NAT control, etc.).

Unlike other CNI implementations where each node is bound to a subnet, in Kube-OVN the Subnet is a global level virtual network configuration, and the addresses of one Subnet can be distributed on any node.

There are some differences in the usage and configuration of Overlay and Underlay Subnets, and this document will describe the common configurations and differentiated features of the different types of Subnets.

"},{"location":"en/guide/subnet/#default-subnet","title":"Default Subnet","text":"

To make it easier for users to get started quickly, Kube-OVN has a built-in default Subnet, all Namespaces that do not explicitly declare subnet affiliation are automatically assigned IPs from the default subnet and the network information. The configuration of this Subnet is specified at installation time, you can refer to Built-in Network Settings for more details. To change the CIDR of the default Subnet after installation please refer to Change Subnet CIDR.

In Overlay mode, the default Subnet uses a distributed gateway and NAT translation for outbound traffic, which behaves much the same as the Flannel's default behavior, allowing users to use most of the network features without additional configuration.

In Underlay mode, the default Subnet uses the physical gateway as the outgoing gateway and enables arping to check network connectivity.

In the Kubernetes network specification, it is required that Nodes can communicate directly with all Pods.

"},{"location":"en/guide/subnet/#overlay-subnet-gateway-settings","title":"Overlay Subnet Gateway Settings","text":"

This feature only works for Overlay mode Subnets, Underlay type Subnets need to use the underlying physical gateway to access the external network.

Pods under the Overlay Subnet need to access the external network through a gateway, and Kube-OVN currently supports two types of gateways: distributed gateway and centralized gateway which can be changed in the Subnet spec.

Both types of gateways support the natOutgoing setting, which allows the user to choose whether snat is required when the Pod accesses the external network.

"},{"location":"en/guide/subnet/#distributed-gateway","title":"Distributed Gateway","text":"

The default type of gateway for the Subnet, each node will act as a gateway for the pod on the current node to access the external network. The packets from container will flow into the host network stack from the local ovn0 NIC, and then forwarding the network according to the host's routing rules. When natOutgoing is true, the Pod will use the IP of the current host when accessing the external network.

Example of a Subnet, where the gatewayType field is distributed:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: distributed\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: distributed\n  natOutgoing: true\n
"},{"location":"en/guide/subnet/#centralized-gateway","title":"Centralized Gateway","text":"

Note: Pods under a centralized subnet cannot be accessed through hostport or a NodePort type Service with externalTrafficPolicy: Local.

If you want traffic within the Subnet to access the external network using a fixed IP for security operations such as auditing and whitelisting, you can set the gateway type in the Subnet to centralized. In centralized gateway mode, packets from Pods accessing the external network are first routed to the ovn0 NIC of a specific nodes, and then outbound through the host's routing rules. When natOutgoing is true, the Pod will use the IP of a specific nodes when accessing the external network.

The centralized gateway example is as follows, where the gatewayType field is centralized and gatewayNode is the NodeName of the particular machine in Kubernetes.

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n  name: centralized\nspec:\n  protocol: IPv4\n  cidrBlock: 10.166.0.0/16\n  default: false\n  excludeIps:\n  - 10.166.0.1\n  gateway: 10.166.0.1\n  gatewayType: centralized\n  gatewayNode: \"node1,node2\"\n  natOutgoing: true\n
  • If a centralized gateway wants to specify a specific NIC of a machine for outbound networking, gatewayNode format can be changed to kube-ovn-worker:172.18.0.2, kube-ovn-control-plane:172.18.0.3.
  • The centralized gateway defaults to primary-backup mode, with only the primary node performing traffic forwarding. If you need to switch to ECMP mode, please refer to ECMP Settings.
  • The spec field enableEcmp has been added to the subnet crd definition since Kube-OVN v1.12.0 to migrate the ECMP switch to the subnet level. You can set whether to enable ECMP mode based on different subnets. The enable-ecmp parameter in the kube-ovn-controller deployment is no longer used. After the previous version is upgraded to v1.12.0, the subnet switch will automatically inherit the value of the original global switch parameter.
"},{"location":"en/guide/subnet/#subnet-acl","title":"Subnet ACL","text":"

For scenarios with fine-grained ACL control, Subnet of Kube-OVN provides ACL to enable fine-grained rules.

The ACL rules in Subnet are the same as the ACL rules in OVN, and you can refer to ovn-nb ACL Table for more details. The supported filed in match can refer to ovn-sb Logical Flow Table.

Example of an ACL rule that allows Pods with IP address 10.10.0.2 to access all addresses, but does not allow other addresses to access itself, is as follows:

The function of Subnet ACL can cover the function of Subnet isolation with better flexibility, we recommend using Subnet ACL to do the corresponding configuration.

By default the Subnets created by Kube-OVN can communicate with each other, and Pods can also access external networks through the gateway.

To control access between Subnets, set private to true in the subnet spec, and the Subnet will be isolated from other Subnets and external networks and can only communicate within the Subnet. If you want to open a whitelist, you can set it by allowSubnets. The CIDRs in allowSubnets can access the Subnet bidirectionally.

Kube-OVN supports multi-tenant isolation level VPC networks. Different VPC networks are independent of each other and can be configured separately with Subnet CIDRs, routing policies, security policies, outbound gateways, EIP, etc.

VPC is mainly used in scenarios where there requires strong isolation of multi-tenant networks and some Kubernetes networking features conflict under multi-tenant networks. For example, node and pod access, NodePort functionality, network access-based health checks, and DNS capabilities are not supported in multi-tenant network scenarios at this time. In order to facilitate common Kubernetes usage scenarios, Kube-OVN has a special design for the default VPC where the Subnet under the VPC can meet the Kubernetes specification. The custom VPC supports static routing, EIP and NAT gateways as described in this document. Common isolation requirements can be achieved through network policies and Subnet ACLs under the default VPC, so before using a custom VPC, please make sure whether you need VPC-level isolation and understand the limitations under the custom VPC.

The fundamental solution requires communication with Kylin and the corresponding network card manufacturer to update the system and drivers. A temporary solution would be to turn off tx offload on the physical NIC, but this would cause a significant degradation in tcp performance.

If the target of diagnose is specified as subnet, the script will create a daemonset on the subnet, and kube-ovn-pinger will detect the connectivity and network delay of all pods in this daemonset, and automatically destroy the daemonset after the test.

If the target of diagnose is specified as IPPorts, the script will let each kube-ovn-pinger pod detect whether the target protocol, IP, and Port are reachable.

As most of the nodes are damaged, the cluster needs to be rebuilt by recovering from one of the database files. If you have previously backed up the database you can use the previous backup file to restore it. If not you can use the following steps to generate a backup from an existing file.

Since the database file in the default folder is a cluster format database file containing information about the current cluster, you can't rebuild the database directly with this file, you need to use ovsdb-tool cluster-to-standalone to convert the format.

Select the first node in the ovn-central environment variable NODE_IPS to restore the database files. If the database file of the first node is corrupted, copy the file from the other machine /etc/origin/ovn to the first machine. Run the following command to generate a database file backup.

docker run -it -v /etc/origin/ovn:/etc/ovn kubeovn/kube-ovn:v1.12.13 bash\ncd /etc/ovn/\novsdb-tool cluster-to-standalone ovnnb_db_standalone.db ovnnb_db.db\novsdb-tool cluster-to-standalone ovnsb_db_standalone.db ovnsb_db.db\n

"},{"location":"en/reference/architecture/","title":"Architecture","text":"

This document describes the general architecture of Kube-OVN, the functionality of each component and how they interact with each other.

Overall, Kube-OVN serves as a bridge between Kubernetes and OVN, combining proven SDN with Cloud Native. This means that Kube-OVN not only implements network specifications under Kubernetes, such as CNI, Service and Networkpolicy, but also brings a large number of SDN domain capabilities to cloud-native, such as logical switches, logical routers, VPCs, gateways, QoS, ACLs and traffic mirroring.

Kube-OVN also maintains a good openness to integrate with many technology solutions, such as Cilium, Submariner, Prometheus, KubeVirt, etc.

"},{"location":"en/reference/architecture/#component-introduction","title":"Component Introduction","text":"

The components of Kube-OVN can be broadly divided into three categories.

  • Upstream OVN/OVS components.
  • Core Controller and Agent.
  • Monitoring, operation and maintenance tools and extension components.

"},{"location":"en/reference/architecture/#upstream-ovnovs-components","title":"Upstream OVN/OVS Components","text":"

This type of component comes from the OVN/OVS community with specific modifications for Kube-OVN usage scenarios. OVN/OVS itself is a mature SDN system for managing virtual machines and containers, and we strongly recommend that users interested in the Kube-OVN implementation read ovn-architecture(7) first to understand what OVN is and how to integrate with it. Kube-OVN uses the northbound interface of OVN to create and coordinate virtual networks and map the network concepts into Kubernetes.

All OVN/OVS-related components have been packaged into images and are ready to run in Kubernetes.

"},{"location":"en/reference/architecture/#ovn-central","title":"ovn-central","text":"

The ovn-central Deployment runs the control plane components of OVN, including ovn-nb, ovn-sb, and ovn-northd.

  • ovn-nb: Saves the virtual network configuration and provides an API for virtual network management. kube-ovn-controller will mainly interact with ovn-nb to configure the virtual network.
  • ovn-sb: Holds the logical flow table generated from the logical network of ovn-nb, as well as the actual physical network state of each node.
  • ovn-northd: translates the virtual network of ovn-nb into a logical flow table in ovn-sb.

Multiple instances of ovn-central will synchronize data via the Raft protocol to ensure high availability.

"},{"location":"en/reference/architecture/#ovs-ovn","title":"ovs-ovn","text":"

ovs-ovn runs as a DaemonSet on each node, with openvswitch, ovsdb, and ovn-controller running inside the Pod. These components act as agents for ovn-central to translate logical flow tables into real network configurations.

"},{"location":"en/reference/architecture/#core-controller-and-agent","title":"Core Controller and Agent","text":"

This part is the core component of Kube-OVN, serving as a bridge between OVN and Kubernetes, bridging the two systems and translating network concepts between them. Most of the core functions are implemented in these components.

"},{"location":"en/reference/architecture/#kube-ovn-controller","title":"kube-ovn-controller","text":"

This component performs the translation of all resources within Kubernetes to OVN resources and acts as the control plane for the entire Kube-OVN system. The kube-ovn-controller listens for events on all resources related to network functionality and updates the logical network within the OVN based on resource changes. The main resources listened including:

Pod\uff0cService\uff0cEndpoint\uff0cNode\uff0cNetworkPolicy\uff0cVPC\uff0cSubnet\uff0cVlan\uff0cProviderNetwork\u3002

Taking the Pod event as an example, kube-ovn-controller listens to the Pod creation event, allocates the address via the built-in in-memory IPAM function, and calls ovn-central to create logical ports, static routes and possible ACL rules. Next, kube-ovn-controller writes the assigned address and subnet information such as CIDR, gateway, route, etc. to the annotation of the Pod. This annotation is then read by kube-ovn-cni and used to configure the local network.

"},{"location":"en/reference/architecture/#kube-ovn-cni","title":"kube-ovn-cni","text":"

This component runs on each node as a DaemonSet, implements the CNI interface, and operates the local OVS to configure the local network.

This DaemonSet copies the kube-ovn binary to each machine as a tool for interaction between kubelet and kube-ovn-cni. This binary sends the corresponding CNI request to kube-ovn-cni for further operation. The binary will be copied to the /opt/cni/bin directory by default.

kube-ovn-cni will configure the specific network to perform the appropriate traffic operations, and the main tasks including:

  1. Config ovn-controller and vswitchd.
  2. Handle CNI Add/Del requests:
    1. Create or delete veth pair and bind or unbind to OVS ports.
    2. Configure OVS ports
    3. Update host iptables/ipset/route rules.
  3. Dynamically update the network QoS.
  4. Create and configure the ovn0 NIC to connect the container network and the host network.
  5. Configure the host NIC to implement Vlan/Underlay/EIP.
  6. Dynamically config inter-cluster gateways.
"},{"location":"en/reference/architecture/#monitoring-operation-and-maintenance-tools-and-extension-components","title":"Monitoring, Operation and Maintenance Tools and Extension Components","text":"

These components provide monitoring, diagnostics, operations tools, and external interface to extend the core network capabilities of Kube-OVN and simplify daily operations and maintenance.

Upstream OVN/OVS was originally designed with the goal of a general purpose SDN controller and data plane. Due to some specific usage of the Kubernetes network,Kube-OVN only focused on part of the features. In order to achieve better performance, stability and specific features, Kube-OVN has made some modifications to the upstream OVN/OVS. Users using their own OVN/OVS with Kube-OVN controllers need to be aware of the possible impact of the following changes:

"},{"location":"en/reference/tunnel-protocol/","title":"Tunnel Protocol Selection","text":"

Kube-OVN uses OVN/OVS as the data plane implementation and currently supports Geneve, Vxlan and STT tunnel encapsulation protocols. These three protocols differ in terms of functionality, performance and ease of use. This document will describe the differences in the use of the three protocols so that users can choose according to their situation.

"},{"location":"en/reference/tunnel-protocol/#geneve","title":"Geneve","text":"

The Geneve protocol is the default tunneling protocol selected during Kube-OVN deployment and is also the default recommended tunneling protocol for OVN. This protocol is widely supported in the kernel and can be accelerated using the generic offload capability of modern NICs. Since Geneve has a variable header, it is possible to use 24bit space to mark different datapaths users can create a larger number of virtual networks.

If you are using Mellanox or Corigine SmartNIC OVS offload, Geneve requires a higher kernel version. Upstream kernel of 5.4 or higher, or other compatible kernels that backports this feature.

Due to the use of UDP encapsulation, this protocol does not make good use of the TCP-related offloads of modern NICs when handling TCP over UDP, and consumes more CPU resources when handling large packets.

"},{"location":"en/reference/tunnel-protocol/#vxlan","title":"Vxlan","text":"

Vxlan is a recently supported protocol in the upstream OVN, which is widely supported in the kernel and can be accelerated using the common offload capabilities of modern NICs. Due to the limited length of the protocol header and the additional space required for OVN orchestration, there is a limit to the number of datapaths that can be created, with a maximum of 4096 datapaths and a maximum of 4096 ports under each datapath. Also, inport-based ACLs are not supported due to header length limitations.

Vxlan offloading is supported in common kernels if using Mellanox or Corigine SmartNIC.

Due to the use of UDP encapsulation, this protocol does not make good use of the TCP-related offloads of modern NICs when handling TCP over UDP, and consumes more CPU resources when handling large packets.

"},{"location":"en/reference/tunnel-protocol/#stt","title":"STT","text":"

The STT protocol is an early tunneling protocol supported by the OVN that uses TCP-like headers to take advantage of the TCP offload capabilities common to modern NICs and significantly increase TCP throughput. The protocol also has a long header to support full OVN capabilities and large-scale datapaths.

This protocol is not supported in the kernel. To use it, you need to compile an additional OVS kernel module and recompile the new version of the kernel module when upgrading the kernel.

This protocol is not currently supported by the SmartNic and cannot use the offloading capability of OVS offloading.

Kube-OVN configures load balancing for each Kubernetes Service on a logical switch on each subnet. When a Pod accesses other Pods by accessing the Service IP, a network packet is constructed with the Service IP as the destination address and the MAC address of the gateway as the destination MAC address. After the network packet enters the logical switch, load balancing will intercept and DNAT the network packet to modify the destination IP and port to the IP and port of one of the Endpoint corresponding to the Service. Since the logical switch does not modify the Layer 2 destination MAC address of the network packet, the network packet will still be delivered to the physic gateway after entering the physic switch, and the physic gateway will be required to forward the network packet.

By default, the default subnet uses Geneve to encapsulate cross-host traffic, and build an overlay network on top of the infrastructure.

For the case that you want the container network to use the physical network address directly, you can set the default subnet of Kube-OVN to work in Underlay mode, which can directly assign the address resources in the physical network to the containers, achieving better performance and connectivity with the physical network.

"},{"location":"en/start/underlay/#limitation","title":"Limitation","text":"

Since the container network in this mode uses physical network directly for L2 packet forwarding, L3 functions such as SNAT/EIP, distributed gateway/centralized gateway in Overlay mode cannot be used. VPC level isolation is also not available for underlay subnet.

"},{"location":"en/start/underlay/#comparison-with-macvlan","title":"Comparison with Macvlan","text":"

The Underlay mode of Kube-OVN is very similar to the Macvlan, with the following major differences in functionality and performance:

  1. Macvlan performs better in terms of throughput and latency performance metrics due to its shorter kernel path and the fact that it does not require OVS for packet processing.
  2. Kube-OVN provides arp-proxy functionality through flow tables to mitigate the risk of arp broadcast storms on large-scale networks.
  3. Since Macvlan works at the bottom of the kernel and bypasses the host netfilter, Service and NetworkPolicy functionality requires additional development. Kube-OVN provides Service and NetworkPolicy capabilities through the OVS flow table.
  4. Kube-OVN Underlay mode provides additional features such as address management, fixed IP and QoS compared to Macvlan.
"},{"location":"en/start/underlay/#environment-requirements","title":"Environment Requirements","text":"

In Underlay mode, the OVS will bridge a node NIC to the OVS bridge and send packets directly through that node NIC, relying on the underlying network devices for L2/L3 level forwarding capabilities. You need to configure the corresponding gateway, Vlan and security policy in the underlying network device in advance.

  1. For OpenStack VM environments, you need to turn off PortSecurity on the corresponding network port.
  2. For VMware vSwitch networks, MAC Address Changes, Forged Transmits and Promiscuous Mode Operation should be set to allow.
  3. For Hyper-V virtualization, MAC Address Spoofing should be enabled in VM nic advanced features.
  4. Public clouds, such as AWS, GCE, AliCloud, etc., do not support user-defined Mac, so they cannot support Underlay mode network. In this scenario, if you want to use Underlay, it is recommended to use the VPC-CNI provided by the corresponding public cloud vendor..
  5. The network interface that is bridged into ovs can not be type of Linux Bridge.

For management and container networks using the same NIC, Kube-OVN will transfer the NIC's Mac address, IP address, route, and MTU to the corresponding OVS Bridge to support single NIC deployment of Underlay networks. OVS Bridge name format is br-PROVIDER_NAME\uff0cPROVIDER_NAME is the name of ProviderNetwork (Default: provider).

ProviderNetwork provides the abstraction of host NIC to physical network mapping, unifies the management of NICs belonging to the same network, and solves the configuration problems in complex environments with multiple NICs on the same machine, inconsistent NIC names and inconsistent corresponding Underlay networks.

Create ProviderNetwork as below:

apiVersion: kubeovn.io/v1\nkind: ProviderNetwork\nmetadata:\n  name: net1\nspec:\n  defaultInterface: eth1\n  customInterfaces:\n    - interface: eth2\n      nodes:\n        - node1\n  excludeNodes:\n    - node2\n

Note: The length of the ProviderNetwork resource name must not exceed 12.

  • defaultInterface: The default node NIC name. When the ProviderNetwork is successfully created, an OVS bridge named br-net1 (in the format br-NAME) is created in each node (except excludeNodes) and the specified node NIC is bridged to this bridge.
  • customInterfaces: Optionally, you can specify the NIC to be used for a specific node.
  • excludeNodes: Optional, to specify nodes that do not bridge the NIC. Nodes in this list will be added with the net1.provider-network.ovn.kubernetes.io/exclude=true tag.

Other nodes will be added with the following tags:

Key Value Description net1.provider-network.ovn.kubernetes.io/ready true bridge work finished, ProviderNetwork is ready on this node net1.provider-network.ovn.kubernetes.io/interface eth1 The name of the bridged NIC in the node. net1.provider-network.ovn.kubernetes.io/mtu 1500 MTU of bridged NIC in node

If an IP has been configured on the node NIC, the IP address and the route on the NIC are transferred to the corresponding OVS bridge.

"},{"location":"en/start/underlay/#logical-gateway","title":"Logical Gateway","text":"

For cases where no gateway exists in the physical network, Kube-OVN supports the use of logical gateways configured in the subnet in Underlay mode. To use this feature, set spec.logicalGateway to true for the subnet:

apiVersion: kubeovn.io/v1\nkind: Subnet\nmetadata:\n   name: subnet1\nspec:\n   protocol: IPv4\n   cidrBlock: 172.17.0.0/16\n   gateway: 172.17.0.1\n   vlan: vlan1\n   logicalGateway: true\n

When this feature is turned on, the Pod does not use an external gateway, but a Logical Router created by Kube-OVN to forward cross-subnet communication.

"},{"location":"en/start/underlay/#interconnection-of-underlay-and-overlay-networks","title":"Interconnection of Underlay and Overlay Networks","text":"

If a cluster has both Underlay and Overlay subnets, by default, Pods in the Overlay subnet can access the Pod IPs in the Underlay subnet via a gateway using NAT. From the perspective of Pods in the Underlay subnet, the addresses in the Overlay subnet are external, and require the underlying physical device to forward, but the underlying physical device does not know the addresses in the Overlay subnet and cannot forward. Therefore, Pods in the Underlay subnet cannot access Pods in the Overlay subnet directly via Pod IPs.

If you need to enable communication between Underlay and Overlay networks, you need to set the u2oInterconnection of the subnet to true. In this case, Kube-OVN will use an additional Underlay IP to connect the Underlay subnet and the ovn-cluster logical router, and set the corresponding routing rules to enable communication. Unlike the logical gateway, this solution only connects the Underlay and Overlay subnets within Kube-OVN, and other traffic accessing the Internet will still be forwarded through the physical gateway.

"},{"location":"en/start/underlay/#specify-logical-gateway-ip","title":"Specify logical gateway IP","text":"

After the interworking function is enabled, an IP from the subnet will be randomly selected as the logical gateway. If you need to specify the logical gateway of the Underlay Subnet, you can specify the field u2oInterconnectionIP.

"},{"location":"en/start/underlay/#specify-custom-vpc-for-underlay-subnet-connection","title":"Specify custom VPC for Underlay Subnet connection","text":"

By default, the Underlay Subnet will communicate with the Overlay Subnet on the default VPC. If you want to specify to communicate with a certain VPC, after setting u2oInterconnection to true, specify the subnet.spec.vpc field as the name of the VPC.

"},{"location":"en/start/underlay/#notice","title":"Notice","text":"

If you have an IP address configured on the network card of the node you are using, and the operating system configures the network using Netplan (such as Ubuntu), it is recommended that you set the renderer of Netplan to NetworkManager and configure a static IP address for the node's network card (disable DHCP).

network:\n  renderer: NetworkManager\n  ethernets:\n    eth0:\n      dhcp4: no\n      addresses:\n        - 172.16.143.129/24\n  version: 2\n

If you want to modify the IP or routing configuration of the network card, you need to execute the following commands after modifying the Netplan configuration:

netplan generate\n\nnmcli connection reload netplan-eth0\nnmcli device set eth0 managed yes\n

After executing the above commands, Kube-OVN will transfer the IP and routing from the network card to the OVS bridge.

If your operating system manages the network using NetworkManager (such as CentOS), you need to execute the following command after modifying the network card configuration:

nmcli connection reload eth0\nnmcli device set eth0 managed yes\nnmcli -t -f GENERAL.STATE device show eth0 | grep -qw unmanaged || nmcli device reapply eth0\n

Notice\uff1aIf the host nic's MAC is changed, Kube-OVN will not change the OVS bridge's MAC unless kube-ovn-cni is restarted.

When physical networks enable hairpin or similar behaviors, problems such as gateway check failure when creating Pods and abnormal network communication of Pods may occur. This is because the default MAC learning function of OVS bridge does not support this kind of network environment.

一键安装

Kube-OVN 提供了一键安装脚本,可以帮助你快速安装一个高可用,生产就绪的 Kube-OVN 容器网络,默认部署为 Overlay 类型网络。

从 Kube-OVN v1.12.0 版本开始,支持 Helm Chart 安装,默认部署为 Overlay 类型网络。

如果默认网络需要搭建 Underlay/Vlan 网络,请参考 Underlay 网络支持

安装前请参考准备工作确认环境配置正确。

脚本安装

下载安装脚本

我们推荐在生产环境使用稳定的 release 版本,请使用下面的命令下载稳定版本安装脚本:

wget https://raw.githubusercontent.com/kubeovn/kube-ovn/release-1.12/dist/images/install.sh
 

如果对 master 分支的最新功能感兴趣,想使用下面的命令下载开发版本部署脚本:

wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/images/install.sh
 

修改配置参数

使用编辑器打开脚本,并修改下列变量为预期值:

REGISTRY="kubeovn"                     # 镜像仓库地址
-VERSION="v1.12.12"                      # 镜像版本/Tag
