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.


werf kubectl config set PROPERTY_NAME PROPERTY_VALUE [options]


  # Set the server field on the my-cluster cluster to
  kubectl config set
  # Set the certificate-authority-data field on the my-cluster cluster
  kubectl config set $(echo "cert_data_here" | base64 -i -)
  # Set the cluster field in the my-context context to my-cluster
  kubectl config set 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


            When writing a []byte PROPERTY_VALUE, write the given string directly without base64

            Username to impersonate for the operation. User could be a regular user or a service    
            account in a namespace.
            Group to impersonate for the operation, this flag can be repeated to specify multiple   
            UID to impersonate for the operation.
            Default cache directory
            Path to a cert file for the certificate authority
            Path to a client certificate file for TLS
            Path to a client key file for TLS
            The name of the kubeconfig cluster to use
            The name of the kubeconfig context to use (default $WERF_KUBE_CONTEXT)
            If true, opt-out of response compression for all requests to the server
            Use specified dir to store werf cache files and dirs (default $WERF_HOME or ~/.werf)
            If true, the server`s certificate will not be checked for validity. This will make your 
            HTTPS connections insecure (default $WERF_SKIP_TLS_VERIFY_REGISTRY)
            Kubernetes config data as base64 string (default $WERF_KUBE_CONFIG_BASE64 or            
            use a particular kubeconfig file
            Require server version to match client version
  -n, --namespace=''
            If present, the namespace scope for this CLI request
            Password for basic authentication to the API server
            Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)
            Name of the file to write the profile to
            The length of time to wait before giving up on a single server request. Non-zero values 
            should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don`t 
            timeout requests.
  -s, --server=''
            The address and port of the Kubernetes API server
            Server name to use for server certificate validation. If it is not provided, the        
            hostname used to contact the server is used
            Use specified dir to store tmp files and dirs (default $WERF_TMP_DIR or system tmp dir)
            Bearer token for authentication to the API server
            The name of the kubeconfig user to use
            Username for basic authentication to the API server
            Treat warnings received from the server as errors and exit with a non-zero exit code
