!!! info
|
||
|
|
[**Kubernetes**](https://kubernetes.io) is an open-source container orchestration system for automating software deployment, scaling, and management.
|
||
|
|
|
||
|
|
The `kubectl` section consists of [`kubectl_version`](#kubernetes-version-kubectl_version) and [`kubectl_context`](#kubernetes-context-kubectl_context) subsections. It is shown only when `kubectl` can connect to Kubernetes cluster.

## Kubernetes version `kubectl_version`

## Kubernetes context `kubectl_context`
|
||
|
|
|
||
|
|
The `kubectl_context` section shows an active Kubernetes context, which consists of a cluster name and a namespace name (when working in a non-default namespace).
|
||
|
|
|
||
|
|
!!! tip
|
||
|
|
If your cluster name (and thus context name) is too long, you can give it a shorter name using:
|
||
|
|
|
||
|
|
```zsh
|
||
|
|
kubectl config rename-context very_long_context_name name
|
||
|
|
```
|
||
|
|
|
||
|
|
### Defining color base on current context or namespace
|
||
|
|
|
||
|
|
To set the section to a different color based on context or namespace, you can define an array of pair values in which the first value of a pair is a color name to use and the second value is a regular expression pattern to match against the section text (context name and/or namespace). The first matched pattern will determine the color, so list order can be used to prioritize patterns.
|
||
|
|
|
||
|
|
Here is an example:
|
||
|
|
|
||
|
|
```zsh title=".zshrc"
|
||
|
|
SPACESHIP_KUBECTL_CONTEXT_COLOR_GROUPS=(
|
||
|
|
# red if namespace is "kube-system"
|
||
|
|
red '\(kube-system)$'
|
||
|
|
|
||
|
|
# else, green if "dev-01" is anywhere in the context or namespace
|
||
|
|
green dev-01
|
||
|
|
|
||
|
|
# else, red if context name ends with ".k8s.local" _and_ namespace is "system"
|
||
|
|
red '\.k8s\.local \(system)$'
|
||
|
|
|
||
|
|
# else, yellow if the entire content is "test-" followed by digits, and no namespace is displayed
|
||
|
|
yellow '^test-[0-9]+$'
|
||
|
|
)
|
||
|
|
```
