github-actions特殊用法

# 由来

Github Actions是github被微软收购以后推出的一项功能强大的便利服务，入门教程可以看看阮一峰的教程。本文主要列一些官方的文档做备份，比如多个actions怎么顺序执行，怎么互相调用

# 最简单的工作流

文章将以这个简单的工作流不断添加内容

name: quickStart

  VERSION: 20220304

  job1:
    name: '示例'
    runs-on: ubuntu-latest

# 同一个yml中顺序执行

name: quickStart
on: push

env:
  VERSION: 20220304

jobs:
  job1:
    name: '示例'
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

  job2:
    name: '示例2'
    nedds: job1
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

  job3:
    name: '示例3'
    nedds: [job1,job2]
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

上面的示例中可以看到有个“nedds”字段，这个字段表示执行顺序的依赖管理。
job2依赖job1执行成功，job3依赖job1和job3全部执行成功。
所以job的执行顺序为：job1 -> job2 -> job3。
但是这样也有一个问题，只有job1执行成功才能执行job2，如果执行失败也继续执行job2，就需要下面的写法。

name: quickStart
on: push

env:
  VERSION: 20220304

jobs:
  job1:
    name: '示例'
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

  job2:
    name: '示例2'
    nedds: job1
    if: ${{ always() }} # 注意这里的用法
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

  job3:
    name: '示例3'
    nedds: [job1,job2]
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

此时我需要在文件1.yml的工作流执行完成或者失败以后执行文件2.yml怎么办？这里可以采用on搭配workflow_run。

When using the workflow_run event, you can specify what branches the triggering workflow must run on in order to trigger your workflow.
The branches and branches-ignore filters accept glob patterns that use characters like *, **, +, ?, ! and others to match more than one branch name. If a name contains any of these characters and you want a literal match, you need to escape each of these special characters with . 有关 glob 模式的更多信息，请参阅“过滤器模式备忘清单”。
For example, a workflow with the following trigger will only run when the workflow named Build runs on a branch whose name starts with releases/:

文件1.yml

name: quickStart-1
on: push

env:
  VERSION: 20220304

jobs:
  job1:
    name: '示例'
    runs-on: ubuntu-latest
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION

    runs-on: ubuntu-latest
    # 只有指定的工作流成功运行，本工作流才能被执行
    if: ${{ github.event.workflow_run.conclusion == 'success' }}
    steps:
    - name: '输出版本'
      run: |
        echo $VERSION
