Example Playbooks

In this example the Ansible role will install (or update) the GitHub Actions Runner service (latest available version). The runner will be registered for my_awesome_repo GitHub repo. Runner service will be stated and will run under the same user as the Ansible is using for ssh connection (ansible).

---
- name: Install GitHub Actions Runner
  hosts: all
  user: ansible
  become: yes
  vars:
    - github_account: github-access-user
    - github_repo: my_awesome_repo
  roles:
    - role: monolithprojects.github_actions_runner

Same example as above, but runner will be added to an organization and deployed on GitHub Enterprise Server.

---
- name: Install GitHub Actions Runner
  hosts: all
  user: ansible
  become: yes
  vars:
    - github_account: my_awesome_org
    - runner_org: yes
    - runner_on_ghes: yes
  roles:
    - role: monolithprojects.github_actions_runner

If you have a Github Enterprise Cloud license and you want to manage all the self-hosted runners from the enterprise:

---
- name: Install GitHub Actions Runner
  hosts: all
  user: automation
  become: yes
  vars:
    - github_enterprise: my_awesome_enterprise
    - runner_org: no
  roles:
    - role: monolithprojects.github_actions_runner

In this example the Ansible role will deploy (or update) the GitHub Actions runner service (version 2.165.2) and register the runner for the GitHub repo. Runner service will run under the user runner-user. Runner will be registered with two labels. The runner service will be stopped and disabled. Runner will use custom environment variables (from file named .env in the self-hosted runner application directory).

---
- name: Stop GitHub Actions Runner
  hosts: all
  become: yes
  vars:
    - runner_version: "2.165.2"
    - runner_user: runner-user
    - github_account: github-access-user
    - github_repo: my_awesome_repo
    - runner_state: "stopped"
    - runner_labels:
        - production
        - west
    - custom_env: |
        HTTP_PROXY=http://proxy.local:8080
        http_proxy=http://proxy.local:8080
        HTTPS_PROXY=http://proxy.local:8080
        https_proxy=http://proxy.local:8080
        no_proxy=localhost,127.0.0.1,127.0.0.2

  roles:
    - role: monolithprojects.github_actions_runner

In this example the Ansible role will uninstall the runner service and unregister it from the GitHub Repository.

---
- name: Uninstall GitHub Actions Runner
  hosts: all
  become: yes
  vars:
    - github_account: github-access-user
    - github_repo: my_awesome_repo
    - runner_state: "absent"
  roles:
    - role: monolithprojects.github_actions_runner

Testing with Molecule

Molecule is a testing framework for Ansible. This section is for code contributors.

Prerequisites

• Python
• Docker
• Ansible
• Molecule

Installation

1. Install Python, Docker, and Ansible if you haven't already.
2. Install Molecule and its Docker driver with pip:

pip install molecule[docker]

Sure, here's a basic example of how you might structure a README to explain how to test the monolithprojects.github_actions_runner Ansible role with Molecule:

# monolithprojects.github_actions_runner

This is an Ansible role for setting up GitHub Actions runners.

## Testing with Molecule

[Molecule](https://molecule.readthedocs.io/) is a testing framework for Ansible that we use to test the `monolithprojects.github_actions_runner` role.

### Prerequisites

- Python
- Docker
- Ansible
- Molecule

### Installation

1. Install Python, Docker, and Ansible if you haven't already.
2. Install Molecule and its Docker driver with pip:

```bash
pip install molecule[docker]

Running Tests

1. Navigate to the role's directory:

cd path/to/monolithprojects.github_actions_runner

2. Set Environment variables

export PERSONAL_ACCESS_TOKEN=your_github_pat # Your Personal Access Token to Github
export GITHUB_ACCOUNT=your_account # Your Github Account
export GITHUB_REPO=your_repository # Github Repository where you want to setup the Runner

3. Run Molecule:

molecule test

This will run the molecule test, create a Docker container, run the role against it, run any associated default tests (see molecule/default directory), and then destroy the container.

For more information on using Molecule, see the Molecule documentation.
