Github Actions多文件夹部署：仅变更对应目录时触发部署

你之前用if: contains(github.event.head_commit.message, './Function1')无效的原因很明确：这个条件是检查提交消息里是否包含指定字符串，而非该文件夹下的文件是否实际发生变更。要实现「文件夹变更才触发对应部署」的需求，有两种实用方案：

方案1：拆分独立Job（推荐） #

把每个函数的部署拆成单独的Job，通过paths字段指定触发该Job的文件夹路径。这样只有对应文件夹发生变更时，该Job才会执行，既高效又逻辑清晰。

示例代码：

jobs:
  deploy-function1:
    runs-on: ubuntu-latest
    paths:
      - './Function1/**'
    steps:
    - name: Checkout code
      uses: actions/checkout@v3

    - name: Authenticate to Google Cloud
      uses: google-github-actions/auth@v1
      with:
        credentials_json: ${{ secrets.GCP_SA_DEPLOY_KEY }}

    - name: Set up Google Cloud SDK
      uses: google-github-actions/setup-gcloud@v1
      with:
        project_id: ${{ secrets.GCP_PROJECT_ID }}
        install_components: 'beta'

    - name: Deploy Function 1
      run: ... # 替换为你的实际部署命令

  deploy-function2:
    runs-on: ubuntu-latest
    paths:
      - './Function2/**'
    steps:
    - name: Checkout code
      uses: actions/checkout@v3

    - name: Authenticate to Google Cloud
      uses: google-github-actions/auth@v1
      with:
        credentials_json: ${{ secrets.GCP_SA_DEPLOY_KEY }}

    - name: Set up Google Cloud SDK
      uses: google-github-actions/setup-gcloud@v1
      with:
        project_id: ${{ secrets.GCP_PROJECT_ID }}
        install_components: 'beta'

    - name: Deploy Function 2
      run: ... # 替换为你的实际部署命令

# 按相同格式复制deploy-function3和deploy-function4的Job配置

方案2：在原Job的Step中添加条件判断 #

如果不想拆分Job，可以在每个部署Step中添加if条件，检查本次提交是否修改了对应文件夹下的文件。github.event.paths会列出所有变更的文件路径，用contains判断是否有路径包含目标文件夹即可：

示例代码：

deploy:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout code
      uses: actions/checkout@v3

    - name: Authenticate to Google Cloud
      uses: google-github-actions/auth@v1
      with:
        credentials_json: ${{ secrets.GCP_SA_DEPLOY_KEY }}

    - name: Set up Google Cloud SDK
      uses: google-github-actions/setup-gcloud@v1
      with:
        project_id: ${{ secrets.GCP_PROJECT_ID }}
        install_components: 'beta'

    - name: Deploy Function 1
      if: contains(github.event.paths, './Function1/')
      run: ...

    - name: Deploy Function 2
      if: contains(github.event.paths, './Function2/')
      run: ...
          
    - name: Deploy Function 3
      if: contains(github.event.paths, './Function3/')
      run: ...

    - name: Deploy Function 4
      if: contains(github.event.paths, './Function4/')
      run: ...

补充说明 #

如果需要支持手动触发Workflow（workflow_dispatch事件），可以给if条件加额外判断，比如：

if: contains(github.event.paths, './Function1/') || github.event_name == 'workflow_dispatch'
