kubectl config set-cluster

Synopsis

Set a cluster entry in kubeconfig.

Specifying a name that already exists will merge new fields on top of existing values for those fields.

kubectl config set-cluster NAME [--server=server] [--certificate-authority=path/to/certificate/authority] [--insecure-skip-tls-verify=true] [--tls-server-name=example.com]

Examples

  # Set only the server field on the e2e cluster entry without touching other values
  kubectl config set-cluster e2e --server=https://1.2.3.4
  
  # Embed certificate authority data for the e2e cluster entry
  kubectl config set-cluster e2e --embed-certs --certificate-authority=~/.kube/e2e/kubernetes.ca.crt
  
  # Disable cert checking for the e2e cluster entry
  kubectl config set-cluster e2e --insecure-skip-tls-verify=true
  
  # Set the custom TLS server name to use for validation for the e2e cluster entry
  kubectl config set-cluster e2e --tls-server-name=my-cluster-name
