Docker: Self-Hosted GitHub Action Runner

Giving Credit Where It's Due: Much of this is based off this article: https://testdriven.io/blog/github-actions-docker/

What is this?

This is a Dockerfile for creating a self-registering, self-hosted GitHub Action runner.

How do I use it?

Build the Image

🚨 The platform flag is needed if you're building on arch64 device like an Apple Silicon based Mac.

docker build --platform linux/amd64 -t github-action-runner .

Run some Containers Based on the Image

docker run -d --env ACCESS_TOKEN=${ACCESS_TOKEN} --env ORGANIZATION=${ORGANIZATION} --env REPO=${REPO} --name github-runner-1 github-action-runner

docker run -d --env ACCESS_TOKEN=${ACCESS_TOKEN} --env ORGANIZATION=${ORGANIZATION} --env REPO=${REPO} --name github-runner-2 github-action-runner

docker run -d --env ACCESS_TOKEN=${ACCESS_TOKEN} --env ORGANIZATION=${ORGANIZATION} --env REPO=${REPO} --name github-runner-3 github-action-runner

This Image does support also registering at an organization wide level by not including the REPO flag in the above example commands:

Example

docker run -d --env ACCESS_TOKEN=${ACCESS_TOKEN} --env ORGANIZATION=${ORGANIZATION} --env REPO=${REPO} --name github-runner github-action-runner
