kconf

An opinionated command line tool for managing multiple kubeconfigs.

Description

kconf works by storing all kubeconfig information in a single file ($HOME/.kube/config). This file is looked at by default when using kubectl.

Usage

Add in a new kubeconfig file:

kconf add /path/to/kubeconfig.conf

or

kconf add /path/to/kubeconfig.conf --context-name=myContext

Remove an existing kubeconfig:

kconf rm myContext

List all saved contexts in the kubeconfig:

kconf ls

View and print a single context's kubeconfig (you can pipe or export to a file):

kconf view myContext

Switch to an existing context:

kconf use myContext

Set a preferred namespace

kconf use myContext -n kube-system

Why?

I was previously managing my kubeconfigs using the $KUBECONFIG environment variable. However, in order to automate this process, you have to do something like this in your rc files:

KUBECONFIG=$(find $HOME/.kube -type f -name '*.conf' 2> /dev/null | sed ':a;N;$!ba;s/\n/:/g')

... that gets you a $KUBECONFIG variable with all your kubeconfigs separated by colons. The problem is that if you're frequently working with new/modified kubeconfigs, you'd have to trigger this command each time something changed.

With the kconf command, there's no need for $KUBECONFIG since kubectl already looks at $HOME/.kube/config by default. Additionally, as soon as you have a new kubeconfig, you can add it pretty easily and quickly.
