# Simple script to help configuring which kubectl CLI to use when you | |
# have a need to keep multiple versions and switch between them. | |
# Install and notes: | |
# 1. put this in /usr/local/bin and chmod +x | |
# 2. keep all the versions of kubectl in the /Applications directory | |
# 3. name kubectl executables with corresponding version - e.g. /Applications/kubectl-1.19.0 | |
# Ref - for where to get versions of kubectl | |
# https://kubernetes.io/docs/tasks/tools/install-kubectl/ | |
