Easily create a new temporary kubeconfig

kubectl-new-env

#!/bin/bash

# Create a new temporary kubeconfig file and display a command to
# configure the current shell to use the new kubeconfig file.
# This is helpful if you interact with multiple OpenShift clusters
# at the same time.
#
# Usage:
#   $(kubectl-new-env)
set -euo pipefail

KUBECONFIG=$(mktemp -t kubeconfig.XXXXX)
chmod og-rwx ${KUBECONFIG}

echo "export KUBECONFIG=${KUBECONFIG}"

I have set this up on my system so a new KubeConfig is created whenever I open a new shell which works well for my use case.

1. Add this script above somewhere in your filesystem
2. chmod +x <path-to-script>
3. Add this to your .bashrc: $(<path-to-file-above)
