Useful Kubernetes Tools

After a discussion on today’s Office Hours, we figured it’d be worth getting a Useful Tool thread going :slight_smile:

The Kubernetes ecosystem is vast and it can be easy to miss some of the great things the community produces.

Kubectx and Kubens - They let you quickly switch between contexts and namespaces.


Another tool is Draft. What I really like is the ability to debug applications as they run inside Kubernetes. There was a demo in SIG Apps that you can find at


Shipper - multicluster deployments


ksec - A command line tool that simplifies the management of Kubernetes Secrets.

I don’t want to spam the thread too much, but another really useful one for folks getting started with Kubernetes is kube-score. It’s like a linter for Kubernetes objects. It will warn users if you do things like use latest in your image, don’t set resource limits etc. Also easy to integrate into CI pipeline.
