kubectl config set

Synopsis

Set an individual value in a kubeconfig file.

PROPERTY_NAME is a dot delimited name where each token represents either an attribute name or a map key. Map keys may not contain dots.

PROPERTY_VALUE is the new value you want to set. Binary fields such as 'certificate-authority-data' expect a base64 encoded string unless the --set-raw-bytes flag is used.

Specifying an attribute name that already exists will merge new fields on top of existing values.

kubectl config set PROPERTY_NAME PROPERTY_VALUE

Examples

  # Set the server field on the my-cluster cluster to https://1.2.3.4
  kubectl config set clusters.my-cluster.server https://1.2.3.4
  
  # Set the certificate-authority-data field on the my-cluster cluster
  kubectl config set clusters.my-cluster.certificate-authority-data $(echo "cert_data_here" | base64 -i -)
  
  # Set the cluster field in the my-context context to my-cluster
  kubectl config set contexts.my-context.cluster my-cluster
  
  # Set the client-key-data field in the cluster-admin user using --set-raw-bytes option
  kubectl config set users.cluster-admin.client-key-data cert_data_here --set-raw-bytes=true

Options

-h, --help
