kubectl-klock

demonstration animation

A kubectl plugin to render the kubectl get pods --watch output in a much more readable fashion.

Think of it as running watch kubectl get pods, but instead of polling, it uses the regular watch feature to stream updates as soon as they occur.

kubectl krew install klock

Snap

sudo snap install klock

scoop bucket add applejag https://github.com/applejag/applejag-bucket
scoop install applejag/kubectl-klock
