What's New

Automatic cluster discovery with cluster-api
For users who are using cluster-api (sigs.k8s.io/cluster-api), Karmada is now able to automatically discover & join clusters when provisioned, and unjoin them in case of destroyed.

Note that this features is implemented as a built-in plugin. To enbale it, simply indicate the following to flags in karmada-controller-manager config:

--cluster-api-kubeconfig string        Path to the cluster-api management cluster kubeconfig file.
--cluster-api-context string           Name of the cluster context in cluster-api management cluster kubeconfig file.

Introduced CommandOverrider and ArgsOverrider to simplify commands customization per cluster
For multi-cluster applications, it's quite common to set different arguments when running on different clusters or environments.
In this release, two overrider plugins: CommandOverrider and ArgsOverrider are introduced, based on industry best practices. These two handy tools allow users to declare complex declarations and avoid configuration mistakes.

Workload types supported now are: Deployment, ReplicaSet, DaemonSet, StatefulSet and Pod, more types including CRDs will be supported in later releases.

Better integration support with Kubernetes ecosystem
The Kubernetes native APIs support and patterns to run cloud-native applications of Karmada make it quite easy to quickly integrate with other projects in the Kubernetes ecosystem.

In release, several useful features that will help Karmada work seamlessly with other systems.

  • ResourceBinding and ClusterResourceBinding now supports present the applied status. (@pigletfly #595)
  • More types of resources now support aggregating status to the resource template, inlcuding Job, Service, and Ingress. (@mrlihanbo #609)
  • argo-cd is also verified to run full featured with Karmada to achieve multi-cluster GitOps.
