Tab Completion for Zsh

Using Ansible

We recommend using the gantsign.antigen role to enable tab completion for Kompose (this must be configured for each user).

- hosts: servers
  roles:
    - role: gantsign.kompose

    - role: gantsign.antigen
      users:
        - username: example
          antigen_bundles:
            - name: kompose
              url: gantsign/zsh-plugins
              location: kompose

Using Antigen

If you prefer to use Antigen directly add the following to your Antigen configuration:

antigen bundle gantsign/zsh-plugins kompose

Manual configuration

To manually configure Zsh add the following to your .zshrc:

eval "$(kompose completion zsh)"
