Enabling shell autocompletion

The Kubebuilder completion script can be generated with the command kubebuilder completion [bash|fish|powershell|zsh]. Note that sourcing the completion script in your shell enables Kubebuilder autocompletion.

Bash

<aside class="note"> <h1>Prerequisites for Bash</h1>

The completion Bash script depends on bash-completion, which means that you have to install this software first (you can test if you have bash-completion already installed). Also, ensure that your Bash version is 4.1+.

bash

$ bash --version

</aside>

Check that bash is an available shell:
bash
```
cat /etc/shells | grep '^.*/bash'
```
If not, add bash to /etc/shells. For example, if bash is at /usr/local/bin/bash:
bash
```
echo "/usr/local/bin/bash" >> /etc/shells
```
Make sure the current user uses bash as their shell.
bash
```
chsh -s /usr/local/bin/bash
```

Add following content to ~/.bash_profile or ~/.bashrc

bash

# kubebuilder autocompletion
if [ -f /usr/local/share/bash-completion/bash_completion ]; then
    . /usr/local/share/bash-completion/bash_completion
fi
    . <(kubebuilder completion bash)

Restart terminal for the changes to be reflected or source the changed bash file.
bash
```
. ~/.bash_profile
```

Zsh

Follow a similar protocol for zsh completion.

Fish

source (kubebuilder completion fish | psub)
