etcd

This customization will be available when the provider-specific cluster configuration patch is included in the ClusterClass.

The etcd configuration can then be manipulated via the cluster variables. If the etcd property is not specified, then the customization will be skipped.

Example

To change the repository and tag for the container image for the etcd pod, specify the following configuration:

apiVersion: cluster.x-k8s.io/v1beta1
kind: Cluster
metadata:
  name: <NAME>
spec:
  topology:
    variables:
      - name: clusterConfig
        value:
          etcd:
            image:
              repository: my-registry.io/my-org/my-repo
              tag: "v3.5.99_custom.0"

Applying this configuration will result in the following value being set:

• KubeadmControlPlaneTemplate:

  • spec:
      kubeadmConfigSpec:
        clusterConfiguration:
          etcd:
            local:
              imageRepository: "my-registry.io/my-org/my-repo"
              imageTag: "v3.5.99_custom.0"
