如何将Docker与GitHub Actions一起使用？ [英] How do I use Docker with GitHub Actions?

问题描述

当我创建GitHub Actions工作流文件时，示例YAML文件包含 runs-on：ubuntu-latest 。 根据文档，我只有几个版本的Ubuntu，Windows Server和macOS X之间的选项。

When I create a GitHub Actions workflow file, the example YAML file contains runs-on: ubuntu-latest. According to the docs, I only have the options between a couple versions of Ubuntu, Windows Server and macOS X.

我认为GitHub Actions在Docker中运行。如何选择我的Docker映像？

I thought GitHub Actions runs inside Docker. How do I choose my Docker image?

推荐答案

一项工作（作为的一部分）工作流程）在虚拟机中运行。您选择其中一种环境由它们提供（例如 ubuntu-latest 或 windows-2019 ）。

A job (as part of a workflow) runs inside a virtual machine. You choose one of the environments provided by them (e.g. ubuntu-latest or windows-2019).

一项工作由一个或多个步骤组成。使用 run ，一个步骤可能是一个简单的shell命令。但这也可能是操作，使用用途

A job consists of one or more steps. A step may be a simple shell command, using run. But it may also be an action, using uses

name: CI

on: [push]

jobs:
  myjob:
    runs-on: ubuntu-18.04 # linux required if you want to use docker
    steps:
    # Those steps are executed directly on the VM
    - run: ls /
    - run: echo $HOME
    - name: Add a file
      run: touch $HOME/stuff.txt
    # Those steps are actions, which may run inside a container
    - uses: actions/checkout@v1
    - uses: ./.github/actions/my-action
    - uses: docker://continuumio/anaconda3:2019.07

• 运行：< COMMAND> 使用OS的外壳执行命令


• 用途：actions / checkout @ v1 从存储库 checkout actions 中运行用户/组织的操作。 / code>（ https://github.com/act ions / checkout ），主要版本1


• 用途：./。github / actions / my-action 运行在您自己的存储库中在此路径下定义的操作


• 用途：docker：// continuumio / anaconda3：2019.07 运行<$来自用户/组织的c $ c> anaconda3 图片 continuumio ，版本 2019.07 ，来自Docker Hub（ https://hub.docker.com/r/continuumio/anaconda3 ）


• run: <COMMAND> executes the command with the shell of the OS
• uses: actions/checkout@v1 runs the action from the user / organization actions in the repository checkout (https://github.com/actions/checkout), major release 1
• uses: ./.github/actions/my-action runs the action which is defined in your own repository under this path
• uses: docker://continuumio/anaconda3:2019.07 runs the anaconda3 image from user / organization continuumio, version 2019.07, from the Docker Hub (https://hub.docker.com/r/continuumio/anaconda3)

请记住，您如果您想使用Docker，则需要选择Linux发行版作为环境。

请参阅用途和运行以获取更多详细信息。

Take a look at the documentation for uses and run for further details.

还应注意，有一个容器选项，允许您运行通常在要在容器内运行的主机上运行的任何步骤： https://help.github.com/en/articles/workflow-syntax-for-github-actions#jobsjob_idcontainer

It should also be noted that there is a container option, allowing you to run any steps that would usually run on the host to be runned inside a container: https://help.github.com/en/articles/workflow-syntax-for-github-actions#jobsjob_idcontainer
