A Select List of Kubernetes Tools

Just because you have a hammer, doesn’t mean every problem is a nail.

Some of these you’ve probably heard of. Some of them you probably haven’t.

What makes this list special is that they’ve all be useful to me, while developing and operating Kubernetes platforms and workloads.

Hopefully they’re useful to you too!

  • kubectx + kubens — fast cluster & namespace switching
  • kustomize — resource patching (built into kubectl now)
  • krew — find and install kubectl plugins
  • ketall — kubectl get all, but actually get everything
  • kail — tail logs from multiple pods
  • rbac-lookup — lookup which roles a user has
  • kube-capacity — cluster resource requests, limits, and usage overview
  • kube-score — static analysis of resource manifests
  • kube-janitor — resource deletion after TTL
