kubefed unjoin

Unjoin a cluster from a federation

Synopsis

Unjoin a cluster from a federation.

Current context is assumed to be a federation endpoint.
Please use the --context flag otherwise.

kubefed unjoin CLUSTER_NAME --host-cluster-context=HOST_CONTEXT [flags]

Examples

  # Unjoin the specified cluster from a federation.
  # Federation control plane's host cluster context name
  # must be specified via the --host-cluster-context flag
  # to properly cleanup the credentials.
  kubectl unjoin foo --host-cluster-context=bar --cluster-context=baz

Options

      --cluster-context string               Name of the cluster's context in the local kubeconfig. Defaults to cluster name if unspecified.
      --credentials-kubeconfig string        Kubeconfig file path on local file system, which should be used to authenticate with host cluster or the joining cluster (instead of the default kubeconfig).This can be used to override the RBAC based authentication while initialising the federation control plane or joining a cluster to one, even when the cluster exposes the RBAC API.
      --federation-system-namespace string   Namespace in the host cluster where the federation system components are installed (default "federation-system")
  -h, --help                                 help for unjoin
      --host-cluster-context string          Host cluster context
