Description

This module will setup all of the files and configuration needed for GitHub Actions runner to work on Debian (Stretch and Buster) and CentOS7 hosts.

hiera configuration examples

This module supports configuration through hiera.

Creating an organization level Actions runner

github_actions_runner::ensure: present
github_actions_runner::base_dir_name: '/data/actions-runner'
github_actions_runner::package_name: 'actions-runner-linux-x64'
github_actions_runner::package_ensure: '2.277.1'
github_actions_runner::repository_url: 'https://github.com/actions/runner/releases/download'
github_actions_runner::org_name: 'my_github_organization'
github_actions_runner::personal_access_token: 'PAT'
github_actions_runner::user: 'root'
github_actions_runner::group: 'root'
github_actions_runner::instances:
  example_org_instance:
    labels:
      - self-hosted-custom

Note, your personal_access_token has to contain the admin:org permission.

Creating an additional repository level Actions runner

github_actions_runner::instances:
  example_org_instance:
    labels:
      - self-hosted-custom1
  example_repo_instance:
    repo_name: myrepo
    labels:
      - self-hosted-custom2

Note, your personal_access_token has to contain the repo permission.

Instance level overwrites

github_actions_runner::instances:
  example_org_instance:
    ensure: absent
    labels:
      - self-hosted-custom1
  example_repo_instance:
    org_name: overwritten_orgnization
    repo_name: myrepo
    labels:
      - self-hosted-custom2

Adding a global proxy and overwriting an instance level proxy

github_actions_runner::http_proxy: http://proxy.local
github_actions_runner::https_proxy: http://proxy.local
github_actions_runner::instances:
  example_org_instance:
    http_proxy: http://instance_specific_proxy.local
    https_proxy: http://instance_specific_proxy.local
    no_proxy: example.com
    labels:
      - self-hosted-custom1

Github Enterprise examples

To use the module with Github Enterprise Server, you have to define these parameters:

github_actions_runner::github_domain: "https://git.example.com"
github_actions_runner::github_api: "https://git.example.com/api/v3"

In addition to the runner configuration examples above, you can also configure runners on the enterprise level by setting a value for enterprise_name, for example:

github_actions_runner::ensure: present
github_actions_runner::base_dir_name: '/data/actions-runner'
github_actions_runner::package_name: 'actions-runner-linux-x64'
github_actions_runner::package_ensure: '2.277.1'
github_actions_runner::repository_url: 'https://github.com/actions/runner/releases/download'
github_actions_runner::enterprise_name: 'enterprise_name'
github_actions_runner::personal_access_token: 'PAT'
github_actions_runner::user: 'root'
github_actions_runner::group: 'root'
github_actions_runner::instances:

Note, your personal_access_token has to contain the admin:enterprise permission.

Update PATH used by Github Runners

By default, puppet will not modify the values that the runner scripts create when the runner is set.

In case you need to use another value of paths in the environment variable PATH, you can define through hiera. For example:

• For all runners defined:

  github_actions_runner::path:
    - /usr/local/bin
    - /usr/bin
    - /bin
    - /my/own/path

• For just a specific runner:

  github_actions_runner::instances:
    example_org_instance:
      path:
        - /usr/local/bin
        - /usr/bin
        - /bin
        - /my/own/path
      labels:
        - self-hosted-custom

Adding environment variables to runner

The runner uses environment variables to decide pre/post-run scripts: https://docs.github.com/en/actions/hosting-your-own-runners/running-scripts-before-or-after-a-job#triggering-the-scripts

github_actions_runner::env:
  ACTIONS_RUNNER_HOOK_JOB_STARTED: "/cleanup_script"
  FOO: "bar"

Limitations

Tested on Debian 9 (stretch), Debian 10 (buster) and CentOS7 hosts. Full list of operating systems support and requirements are described in metadata.json file.

Development

There are a few guidelines that we need contributors to follow so that we can have a chance of keeping on top of things. For more information, see Puppet Forge module contribution guide.
