kubectl alpha kuberc set

Synopsis

Set values in the kuberc configuration file.

Use --section to specify whether to set defaults or aliases.

For defaults: Sets default flag values for kubectl commands. The --command flag should specify only the command (e.g., "get", "create", "set env"), not resources.

For aliases: Creates command aliases with optional default flag values and arguments. Use --prependarg and --appendarg to include resources or other arguments.

kubectl alpha kuberc set --section (defaults|aliases) --command COMMAND

  kubectl alpha kuberc set --section defaults --command get --option output=wide
  
  # Set default output format for a subcommand
  kubectl alpha kuberc set --section defaults --command "set env" --option output=yaml
  
  # Create an alias 'getn' for 'get' command with prepended 'nodes' resource
  kubectl alpha kuberc set --section aliases --name getn --command get --prependarg nodes --option output=wide
