kubectx and kubens are both great tools which speeds up working with multiple Kubernetes clusters. kubectx allows quickly changing context. kubens allows changing namespace in given context.
kubectx
With kubectl you need to type
kubectl config use-context my-context
With kubectx
kubectx my-context
If you have fzf installed, you can interactively select cluster by just writing kubectx.
kubens
Kubens is similar but it allows setting namespace. Instead of doing
kubectl config set-context --current --namespace=my-namespace
You can do
kubens my-namespace
Fzf selection works here as well.
Installation
For Mac, if you are using Homebrew, it is as simple as doing
brew install kubectx
For other platforms, you can referer here.
