Kubernetes prompt for zsh

A Kubernetes zsh prompt that displays the current cluster cluster and the namespace.

Inspired by several tools used to simplify usage of kubectl

NOTE: If you are not using zsh, check out kube-ps1 designed for bash as well as zsh.


The default prompt assumes you have the kubectl command line utility installed. It can be obtained here:

Install and Set up kubectl

If using this with OpenShift, the oc tool needs installed. It can be obtained from here:

OC Client Tools

Helper utilities

There are several great tools that make using kubectl very enjoyable.

kubectx and kubenx are great for fast switching between clusters and namespaces.

Prompt Structure

The prompt layout is:



In order to use kube-ps1 with Oh My Zsh, you'll need to enable them in the .zshrc file. You'll find the zshrc file in your $HOME directory. Open it with your favorite text editor and you'll see a spot to list all the plugins you want to load.

vim $HOME/.zshrc

Add kube-ps1 to the list of enabled plugins and enable it on the prompt:


PROMPT=$PROMPT'$(kube_ps1) '

Note: the PROMPT example above was tested with the theme robbyrussell

Enabling / Disabling on the current shell

Sometimes the kubernetes information can be anoying, you can easily switch it on and off with the following commands:



Blue was used as the prefix to match the Kubernetes color as closely as possible. Red was chosen as the cluster name to stand out, and cyan for the namespace. Check the customization section for changing them.


The default settings can be overridden in ~/.zshrc
