Because it's fancy-kubectl !

Prerequisites?

You can directly download the fubectl.source and save it in some directory.

Download:

Extra!

Do you want to have the current kubecontext in your prompt?:

export PS1="\[$(kube_ctx_name)\] $PS1"

for the current namespace (this is currently slow, because it calls kubectl every time):

export PS1="\[$(kube_ctx_namespace)\] $PS1"

Customization

fubectl can be customized via following environment variables

• FUBECTL_WATCH_CMD – alterative watch command, e.g. viddy
• FUBECTL_NO_KCL – disable kcl alias, since it may conflict with KCL language CLI
