GitHub Runner - DEPRECATED

This repository is deprecated and unmaintained.

Consider using:

• myoung34/docker-github-actions-runner
• actions/actions-runner-controller

---

---

GitHub allows developers to run GitHub Actions workflows on your own runners. This Docker image allows you to create your own runners on Docker.

For now, there are only Debian Buster (tagged with latest and vX.Y.Z) and Ubuntu Focal (tagged with ubuntu-20.04 and vX.Y.Z-ubuntu-20.04) images, but I may add more variants in the future. Feel free to create an issue if you want another base image.

Important notes

• GitHub recommends that you do NOT use self-hosted runners with public repositories, for security reasons.
• Organization level self-hosted runners are supported (see environment variables), but be advised that the GitHub API for organization level runners is still in public beta and subject to changes.

Usage

Basic usage

Use the following command to start listening for jobs:

docker run -it --name my-runner \
    -e RUNNER_NAME=my-runner \
    -e GITHUB_ACCESS_TOKEN=token \
    -e RUNNER_REPOSITORY_URL=https://github.com/... \
    tcardonne/github-runner

Using Docker inside your Actions

If you want to use Docker inside your runner (ie, build images in a workflow), you can enable Docker siblings by binding the host Docker daemon socket. Please keep in mind that doing this gives your actions full control on the Docker daemon.

docker run -it --name my-runner \
    -e RUNNER_NAME=my-runner \
    -e GITHUB_ACCESS_TOKEN=token \
    -e RUNNER_REPOSITORY_URL=https://github.com/... \
    -v /var/run/docker.sock:/var/run/docker.sock \
    tcardonne/github-runner

Using docker-compose.yml

In docker-compose.yml :

version: "3.7"

services:
    runner:
      image: tcardonne/github-runner:latest
      environment:
        RUNNER_NAME: "my-runner"
        RUNNER_REPOSITORY_URL: ${RUNNER_REPOSITORY_URL}
        #RUNNER_ORGANIZATION_URL: ${RUNNER_ORGANIZATION_URL}
        GITHUB_ACCESS_TOKEN: ${GITHUB_ACCESS_TOKEN}
      volumes:
        - /var/run/docker.sock:/var/run/docker.sock

You can create a .env to provide environment variables when using docker-compose :

RUNNER_REPOSITORY_URL=https://github.com/your_url/your_repo
# or RUNNER_ORGANIZATION_URL=https://github.com/your-organization
GITHUB_ACCESS_TOKEN=the_runner_token

Environment variables

The following environment variables allows you to control the configuration parameters.

Name	Description	Required/Default value
RUNNER_REPOSITORY_URL	The runner will be linked to this repository URL	Required if RUNNER_ORGANIZATION_URL is not provided
RUNNER_ORGANIZATION_URL	The runner will be linked to this organization URL. (Self-hosted runners API for organizations is currently in public beta and subject to changes)	Required if RUNNER_REPOSITORY_URL is not provided
GITHUB_ACCESS_TOKEN	Personal Access Token. Used to dynamically fetch a new runner token (recommended, see below).	Required if RUNNER_TOKEN is not provided.
RUNNER_TOKEN	Runner token provided by GitHub in the Actions page. These tokens are valid for a short period.	Required if GITHUB_ACCESS_TOKEN is not provided
RUNNER_WORK_DIRECTORY	Runner's work directory	"_work"
RUNNER_NAME	Name of the runner displayed in the GitHub UI	Hostname of the container
RUNNER_LABELS	Extra labels in addition to the default: 'self-hosted,Linux,X64' (based on your OS and architecture)	""
RUNNER_REPLACE_EXISTING	"true" will replace existing runner with the same name, "false" will use a random name if there is conflict	"true"

Runner Token

In order to link your runner to your repository/organization, you need to provide a token. There is two way of passing the token :

• via GITHUB_ACCESS_TOKEN (recommended), containing a Personnal Access Token. This token will be used to dynamically fetch a new runner token, as runner tokens are valid for a short period of time.
  • For a single-repository runner, your PAT should have repo scopes.
  • For an organization runner, your PAT should have admin:org scopes.
• via RUNNER_TOKEN. This token is displayed in the Actions settings page of your organization/repository, when opening the "Add Runner" page.

Runner auto-update behavior

The GitHub runner (the binary) will update itself when receiving a job, if a new release is available. In order to allow the runner to exit and restart by itself, the binary is started by a supervisord process.
