【问题描述】：

我有一个 Github Action，其中包括标记、构建和部署 docker 映像。当有拉取请求时，我只需使用此文件进行构建工作：build.yml

# This is a basic workflow to help you get started with Actions

name: Build

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

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  docker:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest
    env:
      DOCKERHUB_REPOSITORY: ${{ secrets.DOCKERHUB_REPOSITORY }}

    # 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@v2

      - name: docker build
        run: | # Tag the image with the commit hash
          docker build -t $DOCKERHUB_REPOSITORY .
          docker tag $DOCKERHUB_REPOSITORY:latest $DOCKERHUB_REPOSITORY:$(git log -1 --pretty=%h)

对于部署，我必须使用此文件构建和部署：deploy.yml

# This is a basic workflow to help you get started with Actions

name: Deploy

# Controls when the action will run. Triggers the workflow on push or pull request
# events but only for the master branch
on:
  push:
    branches: [ master ]

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  docker:
    # The type of runner that the job will run on
    runs-on: ubuntu-latest
    env:
      DOCKERHUB_REPOSITORY: ${{ secrets.DOCKERHUB_REPOSITORY }}

    # 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@v2

      - name: docker login
        env:
          DOCKERHUB_USER: ${{ secrets.DOCKERHUB_USER }}
          DOCKERHUB_ACCESS_TOKEN: ${{ secrets.DOCKERHUB_ACCESS_TOKEN }}
        run: |
          docker login -u $DOCKERHUB_USER -p $DOCKERHUB_ACCESS_TOKEN

      - name: docker build
        run: | # Tag the image with the commit hash
          docker build -t $DOCKERHUB_REPOSITORY .
          docker tag $DOCKERHUB_REPOSITORY:latest $DOCKERHUB_REPOSITORY:$(git log -1 --pretty=%h)

      - name: docker push
        run: |
          docker push $DOCKERHUB_REPOSITORY

对我来说，构建部分有重复，但我没有发现如何在不同文件的作业中使用依赖项。它不工作。

我如何告诉 github 操作部署部分取决于构建？，有 2 个不同的文件。

【解决方案1】：

您可以将它们合并到一个 CI/CD 管道中。这应该由 master 中的 pushes 和 pull_requests 触发。这有几个优点；

如果构建失败，管道将自动中止
（绝对确定，您可以添加if: ${{ success() }}！
没有重复的步骤，docker build 只定义一次。
仍然只能通过使用条件在push 或pull_request 上执行步骤：

if: ${{ github.event_name == 'push' }} // OR
if: ${{ github.event_name == 'pull_request' }}

需要维护的管道更少！
