✅ Docker images for starting self-hosted Github Actions runner(s).

👌 Github Actions self-hosted runner provisioning

Simple Docker images for starting self-hosted Github Actions runner(s).

Github official documentation for self-hosted runners.

🚀 Quick start

Add your self-hosted runner from your repository settings:

• Go to repository > settings > actions
• Click on "Add runner"
• Copy the URL and token

# start a runner on your server

$ docker run -d \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /tmp:/tmp \
    -e GH_REPOSITORY=xxxxxxxxxxxx \
    -e GH_RUNNER_TOKEN=xxxxxxxxxxxxx \
    -e GH_RUNNER_LABELS=label1,label2 \
    samber/github-actions-runner:latest

# .github/workflows/main.yml

on:
  - push

jobs:
  example:
    runs-on: self-hosted
    steps:
      - name: Hello world
        run: echo "Hello world"

Runners with language support (NodeJS, Python3...)

Just select your runner in the Docker image tag.

Currently available:

• samber/github-actions-runner:node
• samber/github-actions-runner:golang
• samber/github-actions-runner:python
• samber/github-actions-runner:java
• samber/github-actions-runner:php

# start a NodeJS runner

$ docker run -d \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /tmp:/tmp \
    -e GH_REPOSITORY=xxxxxxxxxxxx \
    -e GH_RUNNER_TOKEN=xxxxxxxxxxxxx \
    -e GH_RUNNER_LABELS=node \
    samber/github-actions-runner:node

# .github/workflows/main.yml

on:
  - push

jobs:
  frontend:
    runs-on: self-hosted
    steps:
      - uses: actions/checkout@v2
      - name: Fetch dependencies
        run: yarn
      - name: Build application
        run: npm run build
      - name: Execute tests
        run: npm run test

Missing language support ?

You just need to write a Dockerfile starting with FROM samber/github-actions-runner:latest.

You can contribute to this repository or create your own Docker image.

💡 Docker compose

Simple runner

version: '3'

services:

  runner:
    image: samber/github-actions-runner:latest
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /tmp:/tmp
    environment:
      - GH_REPOSITORY=xxxxxxxxxxxx
      - GH_RUNNER_TOKEN=xxxxxxxxxxxxx
      - GH_RUNNER_LABELS=label1,label2 \
    restart: unless-stopped

$ docker-compose up -d

Concurrent executors

$ docker-compose scale runner=3

Runners with language support

You will need to register multiple runners, with different name+tokens.

In the following example, we create 2 self-hosted runners: node and golang, with respective tag: "node" and "golang". We will start 2 instances of each.

version: '3'

services:

  runner-node:
    image: samber/github-actions-runner:node
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /tmp:/tmp
    environment:
      - GH_REPOSITORY=yyyyyyyyyyyyy
      - GH_RUNNER_TOKEN=xxxxxxxxxxxxx
      - GH_RUNNER_LABELS=node \
    restart: unless-stopped

  runner-golang:
    image: samber/github-actions-runner:golang
    volumes:
      - /var/run/docker.sock:/var/run/docker.sock
      - /tmp:/tmp
    environment:
      - GH_REPOSITORY=yyyyyyyyyyyyy
      - GH_RUNNER_TOKEN=zzzzzzzzzzzzz
      - GH_RUNNER_LABELS=golang \
    restart: unless-stopped

$ docker-compose up -d
$ docker-compose scale runner-node=2 runner-golang=2

# .github/workflows/main.yml

on:
  - push

jobs:

  frontend:
    runs-on: [self-hosted, node]
    steps:
      - uses: actions/checkout@v2
      - name: Fetch dependencies
        run: yarn
      - name: Build application
        run: npm run build
      - name: Execute tests
        run: npm run test

  api:
    runs-on: [self-hosted, golang]
    steps:
      - uses: actions/checkout@v2
      - name: Fetch dependencies
        run: go mod download
      - name: Build application
        run: go build -o hello-world
      - name: Execute tests
        run: go testt

🤯 Advanced

Run as root

For whatever (bad 😅) reason, if you need to start runners as root, you have to set container user to root, and add an empty RUNNER_ALLOW_RUNASROOT environment variables.
