Releases

  • 0.6.2-1 (buster )
  • 0.9.3-1 (bookworm )
  • 0.9.5-2 (sid | unstable )

Installation 

apt install kubectx

Completion

Both kubectx and kubens support Tab completion on bash/zsh/fish shells to help with long context names. You don’t have to remember full context names anymore.

Completions will be installed for bash, zsh and fish shells.

Usage

Here’s a kubectx demo:

And here’s a kubens demo:

Examples 

# switch to another cluster that's in kubeconfig
$ kubectx minikube
Switched to context "minikube".

# switch back to previous cluster
$ kubectx -
Switched to context "oregon".

# rename context
$ kubectx dublin=gke_ahmetb_europe-west1-b_dublin
Context "gke_ahmetb_europe-west1-b_dublin" renamed to "dublin".

# change the active namespace on kubectl
$ kubens kube-system
Context "test" set.
Active namespace is "kube-system".

# go back to the previous namespace
$ kubens -
Context "test" set.
Active namespace is "default".

If you have fzf installed, you can also interactively select a context or cluster, or fuzzy-search by typing a few characters. To learn more, read interactive mode →
