⎈ kubectl context/namespace in your fish shell prompt
mkdir -p ~/.config/fish/functions/
cd ~/.config/fish/
git clone https://github.com/aluxian/fish-kube-prompt
ln -s ../fish-kube-prompt/__kube_prompt.fish functions/
ln -s ../fish-kube-prompt/kube_ps.fish functions/Then create or edit ~/.config/fish/functions/fish_prompt.fish to include
__kube_prompt:
function fish_prompt
echo -s (set_color blue) (__kube_prompt) (set_color $fish_color_cwd) " " (prompt_pwd) (set_color normal) "> "
endRunning the kubectl commands to get the context and namespace every time
the prompt is shown would slow down the prompt significantly. Therefore,
fish-kube-prompt caches the context and namespace by only calling kubectl
when the env var KUBECONFIG has changed since the last cache update, or
when the 'last modified' timestamp of the files in KUBECONFIG is newer
than the timestamp of the last cache update.
This was not my idea, I took it from jonmosco/kube-ps1.
You can toggle the prompt on or off like this:
kube_ps on
kube_ps offkube_ps is a simple function that just updates a universal variable
__kube_ps_enabled.
Many choices have been hard-coded (e.g. colors, delimiters). If there's anything you'd like to customize, please add an env var and send a PR.
