The command and resource completion is built into kubectl. You can generate it for bash and zsh.

## Generate completion file

Invoke the following command to generate completion file:

```bash
source <(kubectl completion bash)
source <(kubectl completion zsh)
```

Or permanently store it in a file and source it from `.bashrc`.
Make sure to update it whenever you update `kubectl` version

```bash
kubectl completion bash > kubectl_completion.sh

# In .bashrc
source kubectl_completion.sh
```

There is also completion for `powershell`, but I will leave it to you to check it out.

## Documentation
Check `oc completion --help` to get full documentation about the feature with few more examples.
It is constantly evolving, so it is good to revisit from time to time.

## Environment

The commands were executed using kubectl

<KubeBadge kubernetes='v1.25.3'/>
