如何让我的自托管 GitHub runner 在 docker 容器而不是本机 shell 和操作系统中运行作业？

Question

我将我的 Raspberry Pi 4 注册为 GitHub 的自托管运行器。它可以工作，但所有作业都在本机系统本身上运行。我怎样才能让 GitHub 也在运行器上创建一个 Docker 容器，以便底层系统保持干净？它是 GitLab 的默认行为，我很惊讶它不是 GiHub 的，或者我可能遗漏了什么请帮助我。

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v3

      # Runs a single command using the runners shell
      - name: Run a one-line script
        run: echo Hello, world!

      # Runs a set of commands using the runners shell
      - name: Run blinky for 3 times
        run: /home/jbron/blinky.py

我正在尝试使用 container 上下文实现相同的目的。

我相信它看起来像这样：

# Controls when the workflow will run
on:
  # Triggers the workflow on push or pull request events but only for the "main" branch
  push:
    branches: [ "main" ]
  pull_request:
    branches: [ "main" ]

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  # This workflow contains a single job called "build"
  build:
    # The type of runner that the job will run on
    runs-on: self-hosted
    container:
      # Runner docker image
      image: ubuntu:22.04

    # Steps represent a sequence of tasks that will be executed as part of the job
    steps:
      # Checks-out your repository under $GITHUB_WORKSPACE, so your job can access it
      - uses: actions/checkout@v3

      # Runs a single command using the runners shell
      - name: Run a one-line script
        run: echo Hello, world!

      # Runs a set of commands using the runners shell
      - name: Run blinky for 3 times
        run: /home/jbron/blinky.py
