Merge kubernetes configs

Managing multiple config contexts properly

Sometimes managing k8s cluster could be a pain in the ass, but it should be so. Lets see how we can work this around.

Adding new config

• Put your new config into $HOME/.kube/config-new.
• Backup your current config

cp ~/.kube/config ~/.kube/config-bu  

Merge 2 configs together

KUBECONFIG=$HOME/.kube/config:$HOME/.kube/config-new kubectl config view --merge --flatten > ~/.kube/config

Managing multiple cluster and environemtns

I recommend using kubectx You can now switch between your cluster within a single command

$ kubectx
minikube
prod-cluster
$ kubectx minikube

And environments as well

$ kubens
default
staging
production
development
$ kubens development
