clusterctl completion

The clusterctl completion command outputs shell completion code for the specified shell (bash or zsh). The shell code must be evaluated to provide interactive completion of clusterctl commands. This can be done by sourcing it from the ~/.bash_profile.

Bash

To install it on macOS use Homebrew:

$ brew install bash-completion

Once installed, bash_completion must be evaluated. This can be done by adding the following line to the ~/.bash_profile.

[[ -r "$(brew --prefix)/etc/profile.d/bash_completion.sh" ]] && . "$(brew --prefix)/etc/profile.d/bash_completion.sh"

If bash-completion is not installed on Linux, please install the ‘bash-completion’ package via your distribution’s package manager.

You now have to ensure that the clusterctl completion script gets sourced in all your shell sessions. There are multiple ways to achieve this:

• Source the completion script in your ~/.bash_profile file:

  source <(clusterctl completion bash)
  

• Add the completion script to the /usr/local/etc/bash_completion.d directory:

  clusterctl completion bash >/usr/local/etc/bash_completion.d/clusterctl
  

Zsh

The clusterctl completion script for Zsh can be generated with the command clusterctl completion zsh. Sourcing the completion script in your shell enables clusterctl autocompletion.

To do so in all your shell sessions, add the following to your ~/.zshrc file:

source <(clusterctl completion zsh)

After reloading your shell, clusterctl autocompletion should be working.

If you get an error like complete:13: command not found: compdef, then add the following to the beginning of your ~/.zshrc file:

autoload -Uz compinit
compinit
