github-actions-runner

Image for containerized github actions runner. Also see the Kubernetes operator.

Usage

In order to try mimic as much as possible what is done in the github-hosted runner project, we try to reuse their installer scripts.

So this image will allow you to use the installers from the official virtual-environments project.

But since the original project has been designed to be executed on real VM instead of Docker containers, some scripts can fail, like the ones who try to install snap packages (since snap can't run on Docker).

Here you can find the list of available installers.

Configurations

Github Actions Runner can be configured dynamically using env vars with the following prefix ACTIONS_RUNNER_INPUT_.

At the time of writing the configuration options are:

Config Options:
 --unattended           Disable interactive prompts for missing arguments. Defaults will be used for missing options
 --url string           Repository to add the runner to. Required if unattended
 --token string         Registration token. Required if unattended
 --name string          Name of the runner to configure (default 29b09814cbea)
 --runnergroup string   Name of the runner group to add this runner to (defaults to the default runner group)
 --labels string        Extra labels in addition to the default: 'self-hosted,Linux,X64'
 --work string          Relative runner work directory (default _work)
 --replace              Replace any existing runner with the same name (default false)

So if you want set custom labels you just need to export this env var: ACTIONS_RUNNER_INPUT_LABELS=foobar, 1234

Install packages

To run an installer script and its packages you can just simply run install-from-virtual-env <installer-file-name>. You can find some examples on the Dockerfile.
