如何通过GitHub Action部署第二代Google Cloud Functions

一、更新GitHub Action部署配置 #

修改你的.github/workflows/google-cloud-function.yaml文件，完成以下核心调整：

1. 升级部署Action版本：将旧版google-github-actions/deploy-cloud-functions@v0替换为支持第二代函数的稳定版本（推荐使用@v2）
2. 指定第二代函数标识：在部署步骤的with参数中添加generation: 2，明确部署第二代函数
3. 同步升级关联Action（可选）：将身份验证、代码检出的Action也升级到最新版，提升稳定性

修改后的完整配置示例：

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

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

  # Allows you to run this workflow manually from the Actions tab
  workflow_dispatch:

# A workflow run is made up of one or more jobs that can run sequentially or in parallel
jobs:
  deploy:
    runs-on: ubuntu-latest
    permissions:
      contents: "read"
      id-token: "write"
    steps:
      - name: checkout repo
        uses: "actions/checkout@v4"
      - id: "auth"
        name: "Authenticate to Google Cloud"
        uses: "google-github-actions/auth@v2"
        with:
          workload_identity_provider: "projects/12345/locations/global/workloadIdentityPools/gh-pool/providers/gh-provider"
          service_account: "github-actions-service-account@PROJECT.iam.gserviceaccount.com"
      - id: "deploy"
        uses: "google-github-actions/deploy-cloud-functions@v2"
        with:
          name: "myapp"
          runtime: "python310"
          region: "europe-west1"
          entry_point: "main"
          timeout: 540
          service_account_email: PROJECT@appspot.gserviceaccount.com
          ingress_settings: ALLOW_ALL
          max_instances: 1
          generation: 2 # 核心：指定部署第二代函数
          # 可选：添加第二代专属参数，比如CPU/内存配置
          # cpu: 1
          # memory: 256Mi

      # Example of using the output
      - id: "test"
        run: 'curl "${{ steps.deploy.outputs.url }}"'

二、初始化设置无需额外修改 #

你现有初始化配置中的工作负载身份池关联、服务账号权限绑定步骤完全兼容第二代函数，无需调整。若后续出现权限报错，可确认服务账号是否已拥有roles/cloudfunctions.developer角色（原有配置通常已包含该权限）。
