A guide to swiftly managing your Kubernetes resources using K9s - Earthly Blog

However, one needs to know many commands to fetch metrics and operate a Kubernetes cluster using Kubectl. Though the CLI is robust, commands can quickly become cumbersome to run. For example, here is a command for editing a deployment:
kubectl edit deployment/mydeployment -o yaml --save-configNot the longest command, but typing things like this over an over can get cumbersome. Fortunately, there is a terminal UI called K9s that makes interacting with your cluster faster and easier. It abstracts many common kubectl commands and maps them to just a few shortcut keys or clicks of the mouse.

The longer version of this is in How we handle Ubuntu LTS versions.
