Acknowledgements

kubectx-mode is inspired by kubectx by ahmetb and provides the same functionality in Emacs.

If you also change kubectl context or namespace in a shell, you can trigger a mode line update in Emacs with e.g. emacsclient as a PROMPT_COMMAND:

export PROMPT_COMMAND="emacsclient -e '(kubectx-mode-line-update)' &>/dev/null"
