v1.0.0

To install or upgrade to the stable version, see installation doc.

Changes since v0.10.1

Project

• Bump CustomResourceDefinition(CRD) from v1beta1 to v1
• Bump ValidatingWebhookConfiguration/MutatingWebhookConfiguration from v1beta1 to v1
• Bump dependencies: k8s v1.18 -> v1.20, controller-runtime v0.6.5 -> v0.8.3
• Generate CRDs with original controller-tools and markers

So that Kruise can install into Kubernetes 1.22 and no longer support Kubernetes < 1.16.

New feature: in-place update with env from metadata

When update spec.template.metadata.labels/annotations in CloneSet or Advanced StatefulSet and there exists container env from the changed labels/annotations,
Kruise will in-place update them to renew the env value in containers.

doc

New feature: ContainerLaunchPriority

Container Launch Priority provides a way to help users control the sequence of containers start in a Pod.

It works for Pod, no matter what kind of owner it belongs to, which means Deployment, CloneSet or any other Workloads are all supported.

doc

New feature: ResourceDistribution

For the scenario, where the namespace-scoped resources such as Secret and ConfigMap need to be distributed or synchronized to different namespaces,
the native k8s currently only supports manual distribution and synchronization by users one-by-one, which is very inconvenient.

Therefore, in the face of these scenarios that require the resource distribution and continuously synchronization across namespaces, we provide a tool, namely ResourceDistribution, to do this automatically.

Currently, ResourceDistribution supports the two kind resources --- Secret & ConfigMap.

doc

CloneSet

• Add maxUnavailable field in scaleStrategy to support rate limiting of scaling up.
• Mark revision stable as currentRevision when all pods updated to it, won't wait all pods to be ready (Behavior Change).

WorkloadSpread

• Manage the pods that were created before WorkloadSpread.
• Optimize webhook update and retry during injection.

PodUnavailableBudget

• Add pod no pub-protection annotation.
• PUB controller watch workload replicas changed.

Advanced DaemonSet

• Support in-place update daemon pod.
• Support progressive annotation to control if pods creation should be limited by partition.

SidecarSet

• Fix SidecarSet filter active pods.

UnitedDeployment

• Fix pod NodeSelectorTerms length 0 when UnitedDeployment NodeSelectorTerms is nil.

NodeImage

• Add --nodeimage-creation-delay flag to delay NodeImage creation after Node ready.

Other

• Kruise-daemon watch pods using protobuf.
• Export resync seconds args.
• Fix http checker reload ca.cert.
• Fix E2E for WorkloadSpread, ImagePulling, ContainerLaunchPriority.

Thanks to all our contributors! 😊

v0.10.0

To install or upgrade to the latest version, see installation doc.

Changes since v0.9.0

New feature: WorkloadSpread

WorkloadSpread supports to constrain the spread of stateless workload, which empowers single workload the abilities for multi-domain and elastic deployment.

It can be used with those stateless workloads, such as CloneSet, Deployment, ReplicaSet and even Job.

doc

New feature: PodUnavailableBudget

Kubernetes offers Pod Disruption Budget (PDB) to help you run highly available applications even when you introduce frequent voluntary disruptions. PDB limits the number of Pods of a replicated application that are down simultaneously from voluntary disruptions. However, it can only constrain the voluntary disruption triggered by the Eviction API. For example, when you run kubectl drain, the tool tries to evict all of the Pods on the Node you're taking out of service.

PodUnavailableBudget can achieve the effect of preventing ALL application disruption or SLA degradation, including pod eviction, deletion, inplace-update, ...

doc
