• 推送标签时触发(git push --tags):

on:
  push:
    tags:
      - "v*"

• 新建Release后触发

on:
  release:
    types: [created] # 表示在创建新的 Release 时触发
    # - created

• 设置矩阵策略

jobs:
  build-go-binary:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        goos: [linux, windows, darwin] # 需要打包的系统
        goarch: [amd64, arm64] # 需要打包的架构
        exclude: # 排除某些平台和架构
          - goarch: arm64
            goos: windows

jobs:
  build:
    runs-on: ubuntu-latest
    strategy:
      matrix:
        include:
          - goarch: amd64
            goos: linux
          - goarch: amd64
            goos: darwin

跨平台编译

如果是非 CGO 项目，可以使用Go内置的 交叉编译，但如果是 CGO 项目，上述的交叉编译大概率会失败(相关问题:go-libsass)， 所以我们需要基于不同的平台来进行编译，幸运的是，Github Actions 对此支持的非常好。

name: Build and Test
on:
  push:
    branches:
      - master
  pull_request:
jobs:
  lint:
    strategy:
      matrix:
        platform: [ubuntu-latest, windows-latest, macos-latest]
    runs-on: ${{ matrix.platform }}
    steps:
    - name: hello world
      run: |
        echo "Hello World"

Artifact

GitHub Actions 的 jobs 之间是分布式的，相互独立的。因此上一个 job 中生成的文件不能直接传到下一个 job 中，这其中需要用到一个名为Artifact的东西。你可以把它理解成一块共享的公共空间，第一个 job 把构建好的中间文件上传到Artifact上，下一个 job 再从Artifact中下载。这里使用 GitHub 官方的 Action actions/upload-artifact

本地调试工具: Act

Act源码仓库

使用 Act 本地运行 GitHub Actions

安装Act

1. 直接下载二进制文件：https://github.com/nektos/act/releases
2. go install 源码安装

git clone https://github.com/nektos/act.git
cd act
go install
act --version

# act version 0.2.68

使用Act

输入 act --help 能看帮助内容

• -n：Dry run，用于校验语法，查看基本运行逻辑；
• -j：直接指定触发 Job；
• g：图形化的方式来展示 Action 的流程；
• -e：可以编写一个 JSON 文件来描述 Github 事件，例如一个 PR：
