I recommend that store all the kubernetes config in one folder, maybe ~/.kube/configs. And use this tool to help you mrege all this config files in to one config file ~/.kube/config.

Add this script in ~/.bashrc or ~/.zshrc

rm -f ~/.kube/config
touch ~/.kube/config
kubecm merge -f ~/.kube/configs -c &>> /dev/null

you can replace ~ with your abosulute user home path.

Tips:

1. The filename of each kube config file under folder ~/.kube/configs should have the same name with the context in its file.
