k*alias

Alias scripts for making kubectl smooth.

So smooth you wont even want a gui!

Overview

Drop them into /usr/local/bin or somewhere on your path.

If you organize your folders as context/namespace, then kns will switch contexts and namespace, making a pretty seamless transition between clusters. (It matches the folder name to kubeconfig context using grep, so be not a good idea to have one context name as a substring of another!)

They are safe to run without arguments, and without any, will generally just list resources.

Confirmation prompts protect negative-change actions (uninstall, restart).

You don't have to provide full names for the pod argument; a unique portion of the name will suffice. (This is big part of the smoothness!)

(Except for container names. If a pod has multiple containers you must specify the full container name. i.e. pod:container. If container name is required, it should show you the valid options).

By default the tools operate on the first match. You may want to pass a regex name to grep just the resource you want; if so, wrap it in quotes.

$ krl
NAME                                    READY   UP-TO-DATE   AVAILABLE   AGE
deployment.apps/one-somechart-api    1/1     1            1           27h
deployment.apps/one-somechart-ui     2/2     2            2           27h
deployment.apps/two-somechart-api    1/1     1            1           27h
deployment.apps/two-somechart-ui     2/2     2            2           27h

$ krl one
restart deployment.apps/one-somechart-api? [yN]

$ krl "one.*ui"
restart deployment.apps/one-somechart-ui? [yN]
