# kubectx - show active kubectl context
This plugins adds `kubectx_prompt_info()` function. It shows name of the active
kubectl context (`kubectl config current-context`).
You can use it to customize prompt and know if You are on prod cluster ;)
To use this plugin, add `kubectx` to the plugins array in your zshrc file:
```zsh
plugins=(... kubectx)
```
### Usage
Add to **.zshrc**:
```zsh
# right prompt
RPS1='$(kubectx_prompt_info)'
# left prompt
PROMPT="$PROMPT"'$(kubectx_prompt_info)'
```
### Custom context names
You can rename the default context name for better readability or additional formatting.
These values accept [prompt expansion sequences](http://zsh.sourceforge.net/Doc/Release/Prompt-Expansion.html)
such as `%F{color}`, `%f`, `%K{color}`, `%k`, `%B`, `%b`, `%U`, `%u`, `%S`, `%s`, `%{...%}`.
**Example**: add this to your .zshrc file:
```zsh
kubectx_mapping[minikube]="mini"
kubectx_mapping[context_name_from_kubeconfig]="$emoji[wolf_face]"
kubectx_mapping[production_cluster]="%{$fg[yellow]%}prod!%{$reset_color%}"
# contexts with spaces
kubectx_mapping[context\ with\ spaces]="%F{red}spaces%f"
# don't use quotes as it will break the prompt
kubectx_mapping["context with spaces"]="%F{red}spaces%f" # ti
```
You can also define the whole mapping array at once:
```zsh
typeset -A kubectx_mapping
kubectx_mapping=(
minikube "mini"
context_name_from_kubeconfig "$emoji[wolf_face]"
production_cluster "%{$fg[yellow]%}prod!%{$reset_color%}"
"context with spaces" "%F{red}spaces%f"
)
```
