github-actions - 基于不同分支推送构建和推送到不同 ECR 的 GitHub CI 脚本

Question

我在 GitHub 上有一个项目，我想设置 CI 作业来构建 docker 映像并推送到 AWS ECR。我的要求是——

1. 一个 ci 文件（我已创建.github/workflows/aws.yml）
2. CI 作业必须仅在推送到主分支和沙箱分支时触发
3. 如果推送到沙箱分支，那么应该推送 docker 镜像 ECR1
4. 如果推送到 master 分支，那么 docker 镜像应该被推送到 ECR2

到目前为止，我已经制作了以下 CI 文件

.github/workflows/aws.yml -

  name: CI

  on:
    pull_request:
      branches:
      - master
      - sandbox
    push:
      branches:
      - master
      - sandbox

  env:
    AWS_REPOSITORY_URL_MASTER: ${{ secrets.AWS_REPOSITORY_URL_MASTER }}
    AWS_REPOSITORY_URL_SANDBOX: ${{ secrets.AWS_REPOSITORY_URL_SANDBOX }}
    AWS_ACCESS_KEY_ID: ${{ secrets.AWS_ACCESS_KEY_ID }}
    AWS_SECRET_ACCESS_KEY: ${{ secrets.AWS_SECRET_ACCESS_KEY }}

  jobs:
    build-and-push:
      name: Build and push image to AWS ECR master
      runs-on: ubuntu-latest
      steps:

      - name: Checkout
        uses: actions/checkout@v2

      - name: Setup ECR
        run: $( aws ecr get-login --no-include-email --region ap-south-1)

      - name: Build and tag the image
        run: docker build -t $AWS_REPOSITORY_URL_MASTER .

      - name: Push
        run: docker push $AWS_REPOSITORY_URL_MASTER
    build-and-push-sandbox:
      name: Build and push image to AWS ECR master
      runs-on: ubuntu-latest
      steps:

      - name: Checkout
        uses: actions/checkout@v2

      - name: Setup ECR
        run: $( aws ecr get-login --no-include-email --region ap-south-1)

      - name: Build and tag the image
        run: docker build -t $AWS_REPOSITORY_URL_SANDBOX .

      - name: Push
        run: docker push $AWS_REPOSITORY_URL_SANDBOX

脚本如何区分何时运行build-and-push-master（在主分支推送上build-and-push-sandbox触发）和（在沙箱分支推送上触发）？

Answer 1

在级别添加一个if子句：job

jobs:
    build-and-push:
      name: Build and push image to AWS ECR master
      runs-on: ubuntu-latest
      if: github.ref == 'refs/heads/master'
      steps:

和

    build-and-push-sandbox:
      name: Build and push image to AWS ECR sandbox
      runs-on: ubuntu-latest
      if: github.ref == 'refs/heads/sandbox'
      steps:

或者，由于工作非常相似，您可以尝试统一它们并将环境变量设置$AWS_REPOSITORY为${{ secrets.AWS_REPOSITORY_URL_MASTER }}或${{ secrets.AWS_REPOSITORY_URL_SANDBOX }}，具体取决于 的值github.ref。
