kubectl-pod-node-matrix

WORK IN PROGRESS!!

This plugin shows pod x node matrix with suitable colors to mitigate troubleshooting effort.

Details

Troubleshooting in Kubernetes takes some time and sorting out the real cause sometimes overwhelming. Take an example of a couple of pods are not in running state, but the actual cause is node has insufficient disk space. To reduce the amount of time being spent to this troubleshooting, pod-node-matrix might provide a place for "first look at".

pod-node-matrix returns pods x node matrix. This plugin can clearly indicate that if there is a general node problem, or can strongly suggest that node has no problem and instead deployment, service, etc. of this pod have problem.

Thanks to that, at least assuring that one part is working or not will definitely narrow down the places should be checked.
