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.</p>"},{"location":"en/reference/underlay-topology/#service-backend-is-the-same-node-and-same-subnet-pod","title":"Service Backend is the Same Node and Same Subnet Pod","text":""},{"location":"en/reference/underlay-topology/#service-backend-is-the-same-node-and-different-subnets-pod","title":"Service Backend is the Same Node and Different Subnets Pod","text":"<p> \u200b\u5fae\u4fe1\u7fa4\u200b  Slack  Twitter  Support</p>"},{"location":"en/start/one-step-install/","title":"One-Click Installation","text":"<p>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.</p> <p>Helm Chart installation is supported since Kube-OVN v1.12.0, and the default deployment is Overlay networking.</p> <p>If you need Underlay/Vlan networking as the default container network\uff0cplease read Underlay Installation</p> <p>Before installation please read Prerequisites first to make sure the environment is ready.</p>"},{"location":"en/start/one-step-install/#script-installation","title":"Script Installation","text":""},{"location":"en/start/one-step-install/#download-the-installation-script","title":"Download the installation script","text":"<p>We recommend using the stable release version for production environments, please use the following command to download:</p> <pre><code>wget https://raw.githubusercontent.com/kubeovn/kube-ovn/release-1.12/dist/images/install.sh\n</code></pre> <p>If you are interested in the latest features of the master branch, please use the following command to download:</p> <pre><code>wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/images/install.sh\n</code></pre>"},{"location":"en/start/one-step-install/#modify-configuration-options","title":"Modify Configuration Options","text":"<p>Open the script using the editor and change the following variables to the expected:</p> <pre><code>REGISTRY=\"kubeovn\"                     # Image Repo \nVERSION=\"v1.12.11\"                      # Image Tag\nPOD_CIDR=\"10.16.0.0/16\"                # Default subnet CIDR don't overlay with SVC/NODE/JOIN CIDR\nSVC_CIDR=\"10.96.0.0/12\"                # Be consistent with apiserver's service-cluster-ip-range\nJOIN_CIDR=\"100.64.0.0/16\"              # Pod/Host communication Subnet CIDR, don't overlay with SVC/NODE/POD CIDR\nLABEL=\"node-role.kubernetes.io/master\" # The node label to deploy OVN DB\nIFACE=\"\"                               # The name of the host NIC used by the container network, or if empty use the NIC that host Node IP in Kubernetes\nTUNNEL_TYPE=\"geneve\"                   # Tunnel protocol\uff0cavailable options: geneve, vxlan or stt. stt requires compilation of ovs kernel module\n</code></pre> <p>You can also use regular expression to math NIC names\uff0csuch as <code>IFACE=enp6s0f0,eth.*</code>.</p>"},{"location":"en/start/one-step-install/#run-the-script","title":"Run the Script","text":"<p><code>bash install.sh</code></p> <p>Wait Kube-OVN ready.</p>"},{"location":"en/start/one-step-install/#helm-chart-installation","title":"Helm Chart Installation","text":"<p>Since the installation of Kube-OVN requires setting some parameters, to install Kube-OVN using Helm, you need to follow the steps below.</p>"},{"location":"en/start/one-step-install/#view-the-node-ip-address","title":"View the node IP address","text":"<pre><code>$ kubectl get node -o wide\nNAME                     STATUS     ROLES           AGE   VERSION   INTERNAL-IP   EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME\nkube-ovn-control-plane   NotReady   control-plane   20h   v1.26.0   172.18.0.3    &lt;none&gt;

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.</p>"},{"location":"en/reference/underlay-topology/#service-backend-is-the-same-node-and-same-subnet-pod","title":"Service Backend is the Same Node and Same Subnet Pod","text":""},{"location":"en/reference/underlay-topology/#service-backend-is-the-same-node-and-different-subnets-pod","title":"Service Backend is the Same Node and Different Subnets Pod","text":"<p> \u200b\u5fae\u4fe1\u7fa4\u200b  Slack  Twitter  Support</p>"},{"location":"en/start/one-step-install/","title":"One-Click Installation","text":"<p>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.</p> <p>Helm Chart installation is supported since Kube-OVN v1.12.0, and the default deployment is Overlay networking.</p> <p>If you need Underlay/Vlan networking as the default container network\uff0cplease read Underlay Installation</p> <p>Before installation please read Prerequisites first to make sure the environment is ready.</p>"},{"location":"en/start/one-step-install/#script-installation","title":"Script Installation","text":""},{"location":"en/start/one-step-install/#download-the-installation-script","title":"Download the installation script","text":"<p>We recommend using the stable release version for production environments, please use the following command to download:</p> <pre><code>wget https://raw.githubusercontent.com/kubeovn/kube-ovn/release-1.12/dist/images/install.sh\n</code></pre> <p>If you are interested in the latest features of the master branch, please use the following command to download:</p> <pre><code>wget https://raw.githubusercontent.com/kubeovn/kube-ovn/master/dist/images/install.sh\n</code></pre>"},{"location":"en/start/one-step-install/#modify-configuration-options","title":"Modify Configuration Options","text":"<p>Open the script using the editor and change the following variables to the expected:</p> <pre><code>REGISTRY=\"kubeovn\"                     # Image Repo \nVERSION=\"v1.12.11\"                      # Image Tag\nPOD_CIDR=\"10.16.0.0/16\"                # Default subnet CIDR don't overlay with SVC/NODE/JOIN CIDR\nSVC_CIDR=\"10.96.0.0/12\"                # Be consistent with apiserver's service-cluster-ip-range\nJOIN_CIDR=\"100.64.0.0/16\"              # Pod/Host communication Subnet CIDR, don't overlay with SVC/NODE/POD CIDR\nLABEL=\"node-role.kubernetes.io/master\" # The node label to deploy OVN DB\nIFACE=\"\"                               # The name of the host NIC used by the container network, or if empty use the NIC that host Node IP in Kubernetes\nTUNNEL_TYPE=\"geneve\"                   # Tunnel protocol\uff0cavailable options: geneve, vxlan or stt. stt requires compilation of ovs kernel module\n</code></pre> <p>You can also use regular expression to math NIC names\uff0csuch as <code>IFACE=enp6s0f0,eth.*</code>.</p>"},{"location":"en/start/one-step-install/#run-the-script","title":"Run the Script","text":"<p><code>bash install.sh</code></p> <p>Wait Kube-OVN ready.</p>"},{"location":"en/start/one-step-install/#helm-chart-installation","title":"Helm Chart Installation","text":"<p>Since the installation of Kube-OVN requires setting some parameters, to install Kube-OVN using Helm, you need to follow the steps below.</p>"},{"location":"en/start/one-step-install/#view-the-node-ip-address","title":"View the node IP address","text":"<pre><code>$ kubectl get node -o wide\nNAME                     STATUS     ROLES           AGE   VERSION   INTERNAL-IP   EXTERNAL-IP   OS-IMAGE             KERNEL-VERSION      CONTAINER-RUNTIME\nkube-ovn-control-plane   NotReady   control-plane   20h   v1.26.0   172.18.0.3    &lt;none&gt;
