Github Actions

目录

基本概念

配置文件

name: GitHub Actions Demo
on:
  push:
    branches:
      - main

jobs:
  build:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: 16

      - run: npm install

      - run: npm run build

定触条件

# push 事件触发 workflow
on: push

# push 事件或 pull_request 事件都可以触发 workflow
on: [push, pull_request]

# 只有在 main 分支 push 事件触发 workflow
on:
  push:
    branches:
      - main

# push 事件触发 workflow，但是 docs 目录下的更改 push 事件不触发 workflow
on:
  push:
    paths-ignore:
      - 'docs/**'
# push 事件触发 workflow，
# 包括 sub-project 目录或其子目录中的文件，触发 workflow
# 除非该文件在 sub-project/docs 目录中，不触发 workflow
on:
  push:
    paths:
      - 'sub-project/**'
      - '!sub-project/docs/**'
# 版本发布为 published 时运行工作流程。
on:
  release:
    types: [published]

多项任务

jobs:
  my_first_job:
    name: My first job
  my_second_job:
    name: My second job

多项任务依赖关系

jobs:
  job1:
  job2:
    needs: job1
  job3:
    needs: [job1, job2]

多项任务传递参数

jobs:
  job1:
    runs-on: ubuntu-latest
    # Map a step output to a job output
    outputs:
      output1: ${{ steps.step1.outputs.test }}
      output2: ${{ steps.step2.outputs.test }}
    steps:
      - id: step1
        run: echo "::set-output name=test::hello"
      - id: step2
        run: echo "::set-output name=test::world"
  job2:
    runs-on: ubuntu-latest
    needs: job1
    steps:
      - run: echo ${{needs.job1.outputs.output1}} ${{needs.job1.outputs.output2}}

指定每项任务的虚拟机环境

runs-on: ubuntu-18.04

jobs:
  build:
    runs-on: ubuntu-18.04

指定每项任务的步骤

jobs.<job_id>.steps.name：步骤名称。
jobs.<job_id>.steps.run：该步骤运行的命令或者 action。
jobs.<job_id>.steps.env：该步骤所需的环境变量。

jobs:
  build:
    runs-on: ubuntu-18.04
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: 16
          registry-url: 'https://registry.npmjs.org'

      - run: npm install

      - run: npm run build

一个工作流完成触发另外一个工作流

# ci.yml
name: Node.js CI
on: push

jobs:
  test:
    # Containers must run in Linux based operating systems
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3
      - uses: actions/setup-node@v3
        with:
          node-version: 16

      - name: Install dependencies
        run: npm install

  trigger_tests:
    needs: test
    runs-on: ubuntu-latest
    steps:
      - name: Trigger tests
        uses: actions/github-script@v6
        with:
          script: |
            const res = await github.rest.repos.createDispatchEvent({
              owner: 'jaywcjlove',
              repo: 'typenexus',
              event_type: 'run-deploy'
            });
        env:
          GITHUB_TOKEN: ${{ secrets.GITHUB_TOKEN }}

# main.yml
name: deploy
on:
  repository_dispatch:
    types: [run-deploy]

jobs:
  build:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@v3

常用实例

获取版本信息

- name: Test
  run: |
    # Strip git ref prefix from version
    echo "${{ github.ref }}"
    # VERSION=$(echo "${{ github.ref }}" | sed -e 's,.*/\(.*\),\1,')

    # # Strip "v" prefix from tag name
    # [[ "${{ github.ref }}" == "refs/tags/"* ]] && VERSION=$(echo $VERSION | sed -e 's/^v//')
    echo "$VERSION"

name: CI
on:
  push:
    tags:
      - v*

jobs:
  create-docker-image:
    runs-on: ubuntu-latest
    steps:
      - uses: actions/checkout@master
      # 向 EVN 写入 CURRENT_VERSION 环境变量赋值版本号
      - run: |
          echo "CURRENT_VERSION=${GITHUB_REF#refs/tags/v}" >> $GITHUB_ENV
      # 可以获取到 CURRENT_VERSION 的值
      - run: echo "${{env.CURRENT_VERSION}}"

通过 commit 跳过任务

jobs:
  build:
    if: "!contains(github.event.head_commit.message, 'skip ci')"

获取是否存在 Tag

- run: echo "previous_tag=$(git describe --tags --abbrev=0 2>/dev/null || echo '')" >> $GITHUB_ENV
- name: Generate changelog
  id: changelog
  uses: jaywcjlove/changelog-generator@main
  if: env.previous_tag

修改 package.json

- name: Modify Version
  shell: bash
  run: |
    node -e 'var pkg = require("./package.json"); pkg.version= (new Date().getFullYear().toString().substr(2)) + "." + (new Date().getMonth() + 1) + "." + (new Date().getDate()); require("fs").writeFileSync("./package.json", JSON.stringify(pkg, null, 2))'

提交到 gh-pages 分支

- name: Deploy
  uses: peaceiris/actions-gh-pages@v3

  uses: actions/checkout@v3
  with:
    path: main
    submodules: true

- name: Clone sub repository

    auth_header="$(git config --local --get http.https://github.com/.extraheader)"
    # git submodule sync --recursive
    # git -c "http.extraheader=$auth_header" -c protocol.version=2 submodule update --init --remote --force --recursive --checkout ant.design
