kubectl-podevents

kubectl plugins for viewing all events for your pods.

The idea for this plugins has been shamelessly stolen from Melanie Cebula's QCOn London Talk and enhanced to be slightly less opinionated.

This plugin displays all pod events for pods in your currently configured namespace.

This plugin also supports standard Pod selection arguments as well as one (or multiple pod names) to explicitly grab events for.
