# kubectx(1)
|
||
|
||
kubectx is an utility to manage and switch between kubectl(1) contexts.
|
||
|
||
```
|
||
USAGE:
|
||
kubectx : list the contexts
|
||
kubectx <NAME> : switch to context <NAME>
|
||
kubectx - : switch to the previous context
|
||
kubectx <NEW_NAME>=<NAME> : rename context <NAME> to <NEW_NAME>
|
||
kubectx -h,--help : show this message
|
||
```
|
||
|
||
### Usage
|
||
|
||
```sh
|
||
$ kubectx minikube
|
||
Switched to context "minikube".
|
||
|
||
$ kubectx -
|
||
Switched to context "oregon".
|
||
|
||
$ kubectx -
|
||
Switched to context "minikube".
|
||
|
||
$ kubectx dublin=gke_ahmetb_europe-west1-b_dublin
|
||
Context "dublin" set.
|
||
Aliased "gke_ahmetb_europe-west1-b_dublin" as "dublin".
|
||
```
|
||
|
||
`kubectx` supports <kbd>Tab</kbd> completion on bash/zsh shells to help with
|
||
long context names. You don't have to remember full context names anymore.

## Installation
|
||
|
||
**macOS:**
|
||
|
||
:confetti_ball: Use the [Homebrew](https://brew.sh/) package manager:
|
||
|
||
brew install kubectx
|
||
|
||
This command will set up bash/zsh completion scripts automatically.
|
||
|
||
|
||
- Running `brew install` with `--with-short-names` will install tools with names
|
||
`kctx` and `kns` to prevent prefix collision with `kubectl` name.
|
||
|
||
- If you like to add context/namespace info to your shell prompt (`$PS1`),
|
||
I recommend trying out [kube-ps1](https://github.com/jonmosco/kube-ps1).
|
||
|
||
**Linux:**
|
||
|
||
Since `kubectx`/`kubens` are written in Bash, you should be able to instal
|
||
them to any POSIX environment that has Bash installed.
|
||
|
||
- Download the `kubectx`, `kubens` and `utils.bash` scripts.
|
||
- Either:
|
||
- save them all to somewhere in your `PATH`,
|
||
- or save them to a directory, then create symlinks to `kubectx`/`kubens` from
|
||
somewhere in your `PATH`, like `/usr/local/bin`
|
||
- Make `kubectx` and `kubens` executable (`chmod +x ...`)
|
||
- Figure out how to install bash/zsh [completion scripts](completion/).
