docker-如何在 Github Actions 中指定 Google Cloud Run 元数据？

我有一个 Github Action，它构建一个 docker 映像，然后将其上传到 Container Registry。接下来，我想将此容器部署到具有最小和最大实例的一些特定设置的 Cloud Run 服务，确保 CPU 始终开启，仅内部入口等。文档说这些设置是使用 metadata 设置的，但没有显示示例. 这个元数据应该采用什么格式？

name: Push code to GCP
on:
  push:
    branches: [ main ]
jobs:
  container-build-push-deploy:
    name: Build Container Push to Registry Deploy to Cloud Run
    runs-on: ubuntu-latest
    env:
      IMAGE_NAME: my-image
      PROJECT_ID: my-project-123456
      REGION: us-central1
    steps:
    - name: Checkout
      uses: actions/checkout@v2

    - name: Authenticate With GCP
      id: auth
      uses: google-github-actions/auth@v0
      with:
        credentials_json: ${{ secrets.GCP_CREDENTIALS }}

    - name: Setup Cloud SDK
      uses: google-github-actions/setup-gcloud@v0
      with:
        project_id: ${{ env.PROJECT_ID }}
    
    - name: Tag Release
      id: increment-git-tag
      run: |
        bash ./scripts/git_update.sh -v patch

    - name: Build Docker Image
      run: docker build -t $IMAGE_NAME:latest .
    
    - name: Configure Docker Client
      run: |-
        gcloud auth configure-docker --quiet

    - name: Push Docker Image to Container Registry
      env:
        GIT_TAG: ${{ steps.increment-git-tag.outputs.git-tag }}
      run: |-
        docker tag $IMAGE_NAME:latest gcr.io/$PROJECT_ID/$IMAGE_NAME:latest
        docker tag $IMAGE_NAME:latest gcr.io/$PROJECT_ID/$IMAGE_NAME:$GIT_TAG
        docker push gcr.io/$PROJECT_ID/$IMAGE_NAME:latest
        docker push gcr.io/$PROJECT_ID/$IMAGE_NAME:$GIT_TAG
    
    - name: Deploy to Cloud Run
      env:
        GIT_TAG: ${{ steps.increment-git-tag.outputs.git-tag }}
      uses: google-github-actions/deploy-cloudrun@v0
      with:
        service: my-service
        image: 'gcr.io/${{ env.PROJECT_ID }}/${{ env.IMAGE_NAME }}:${{ env.GIT_TAG }}'
        region: ${{ env.REGION }}
        secrets: |
          /app/path/to/my-secret=my-secret:latest
        metadata:
          min-instances: 1
          max-instances: 1
          ingress: internal
          tag: ${{ env.GIT_TAG }}
          no-cpu-throttling: true
          command: node
          args: |
            /app/path/to/main.js
            arg-1

显然这是最后一次metadata件是错误的，因为with应该是字符串的键值对。这里的正确格式是什么？
