Tab Completion for Zsh

Using Ansible

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

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

    - role: gantsign.antigen
      users:
        - username: example
          antigen_libraries:
            - name: oh-my-zsh
          antigen_bundles:
            - name: kops

Using Antigen

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

antigen bundle kops

Manual configuration

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

eval "$(kops completion zsh)"

Development & Testing

This project uses Molecule to aid in the development and testing; the role is unit tested using Testinfra and pytest.

To develop or test you'll need to have installed the following:

• Linux (e.g. Ubuntu)
• Docker
• Python (including python-pip)
• Ansible
• Molecule

Because the above can be tricky to install, this project includes Molecule Wrapper. Molecule Wrapper is a shell script that installs Molecule and it's dependencies (apart from Linux) and then executes Molecule with the command you pass it.

To test this role using Molecule Wrapper run the following command from the project root:

./moleculew test

Note: some of the dependencies need sudo permission to install.
