kubectxon is a utility to show up the active-context.

USAGE:

  kubectx <NAME>            : switch to context <NAME>
  kubectx -                 : switch to the previous context
  kubectx -c, --current     : show the current context name
  kubectx <NEW_NAME>=<NAME> : rename context <NAME> to <NEW_NAME>
  kubectx <NEW_NAME>=.      : rename current-context to <NEW_NAME>
  kubectx -d <NAME>         : delete context <NAME> ('.' for current-context)
                              (this command won't delete the user/cluster entry
                              that is used by the context)
