Functions

multi-cluster-config

Config files in a directory will be collected and added to $KUBECONFIG at startup shell. So adding and removing file is enough. No more merge of "master-config" needed. Credits to https://github.com/GeertJohan/kube-multi-config

Tools will create ~/.kube-multi directory. Put your cluster configfiles into this directory and restart your shell. kubectl will recognize the new files. To remove config-files just remove it from this directory. kubectl will recognize this immediately.

If ~/.kube-shared directory exists theese file will also merged into $KUBECONFIG environemnt variable. This can be used to share configs with other team members seperated from private config files.

Config files must name *.yaml or *.yml.
