# 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](https://github.com/jonmosco/kube-ps1)
|
|
designed for bash as well as zsh.
|
|
|
|
## Requirements
|
|
|
|
The default prompt assumes you have the kubectl command line utility installed. It
|
|
can be obtained here:
|
|
|
|
[Install and Set up kubectl](https://kubernetes.io/docs/tasks/tools/install-kubectl/)
|
|
|
|
If using this with OpenShift, the oc tool needs installed. It can be obtained from here:
|
|
|
|
[OC Client Tools](https://www.openshift.org/download.html)
|
|
|
|
## Helper utilities
|
|
|
|
There are several great tools that make using kubectl very enjoyable.
|
|
|
|
[kubectx and kubenx](https://github.com/ahmetb/kubectx) are great for
|
|
fast switching between clusters and namespaces.
|
|
|
|
## Prompt Structure
|
|
|
|
The prompt layout is:
|
|
|
|
```
|
|
(<symbol>|<cluster>:<namespace>)
|
|
```
|
|
|
|
## Enabling
|
|
|
|
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.
|
|
|
|
```shell
|
|
vim $HOME/.zshrc
|
|
```
|
|
|
|
Add kube-ps1 to the list of enabled plugins and enable it on the prompt:
|
|
|
|
```shell
|
|
plugins=(
|
|
git
|
|
kube-ps1
|
|
)
|
|
|
|
PROMPT=$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:
|
|
|
|
```shell
|
|
kubeon
|
|
```
|
|
|
|
```shell
|
|
kubeoff
|
|
```
|
|
|
|
## Colors
|
|
|
|
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.
|
|
|
|
## Customization
|
|
|
|
The default settings can be overridden in ~/.zshrc
