Kubernetes CLI Plugin - Doctor
This plugin is obviously inspired from brew doctor :) It will scan your currently target
ed k8s cluster to see if there are anomalies or useful action points that it can report back to you.
This plugin does not change any state or configuration, it merely just scans and gathers information than reports back anomalies.

binary from releases
