快速入门:使用 gcloud CLI 部署 Cloud Run functions 函数

本页介绍了如何使用 gcloud CLI 部署 HTTP Cloud Run functions 函数。

准备工作

  1. Sign in to your Google Cloud account. If you're new to Google Cloud, create an account to evaluate how our products perform in real-world scenarios. New customers also get $300 in free credits to run, test, and deploy workloads.
  2. Install the Google Cloud CLI.

  3. 如果您使用的是外部身份提供方 (IdP),则必须先使用联合身份登录 gcloud CLI

  4. 如需初始化 gcloud CLI,请运行以下命令:

    gcloud init
  5. Create or select a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.
    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  6. 如果您要使用现有项目来完成本指南,请验证您是否拥有完成本指南所需的权限。如果您创建了新项目,则您已拥有所需的权限。

  7. Verify that billing is enabled for your Google Cloud project.

  8. Enable the Artifact Registry, Cloud Build, Cloud Run Admin API, and Cloud Logging APIs:

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

    gcloud services enable artifactregistry.googleapis.com cloudbuild.googleapis.com run.googleapis.com logging.googleapis.com
  9. Install the Google Cloud CLI.

  10. 如果您使用的是外部身份提供方 (IdP),则必须先使用联合身份登录 gcloud CLI

  11. 如需初始化 gcloud CLI,请运行以下命令:

    gcloud init
  12. Create or select a Google Cloud project.

    Roles required to select or create a project

    • Select a project: Selecting a project doesn't require a specific IAM role—you can select any project that you've been granted a role on.
    • Create a project: To create a project, you need the Project Creator role (roles/resourcemanager.projectCreator), which contains the resourcemanager.projects.create permission. Learn how to grant roles.
    • Create a Google Cloud project:

      gcloud projects create PROJECT_ID

      Replace PROJECT_ID with a name for the Google Cloud project you are creating.

    • Select the Google Cloud project that you created:

      gcloud config set project PROJECT_ID

      Replace PROJECT_ID with your Google Cloud project name.

  13. 如果您要使用现有项目来完成本指南,请验证您是否拥有完成本指南所需的权限。如果您创建了新项目,则您已拥有所需的权限。

  14. Verify that billing is enabled for your Google Cloud project.

  15. Enable the Artifact Registry, Cloud Build, Cloud Run Admin API, and Cloud Logging APIs:

    Roles required to enable APIs

    To enable APIs, you need the Service Usage Admin IAM role (roles/serviceusage.serviceUsageAdmin), which contains the serviceusage.services.enable permission. Learn how to grant roles.

    gcloud services enable artifactregistry.googleapis.com cloudbuild.googleapis.com run.googleapis.com logging.googleapis.com
  16. 要为 Cloud Run 服务设置默认项目,请使用以下命令:
     gcloud config set project PROJECT_ID
    PROJECT_ID 替换为您为此快速入门创建的项目的名称。
  17. 如果您通过网域限制组织政策来限制项目的未经身份验证的调用,则您需要按照测试专用服务中的说明访问已部署的服务。

  18. 查看 Cloud Run 价格或使用价格计算器估算费用。
  19. 所需的角色

    如需获得完成本教程所需的权限,请让您的管理员为您授予以下 IAM 角色:

    如需详细了解如何授予角色,请参阅管理对项目、文件夹和组织的访问权限

    您也可以通过自定义角色或其他预定义角色来获取所需的权限。

    授予 Cloud Build 服务账号对项目的访问权限

    除非您替换此行为,否则 Cloud Build 会自动使用 Compute Engine 默认服务账号作为默认 Cloud Build 服务账号来构建源代码和 Cloud Run 资源。

    为了让 Cloud Build 能够构建来源,请向 Cloud Build 服务账号授予项目的 Cloud Run Builder (roles/run.builder) 角色:

    gcloud projects add-iam-policy-binding PROJECT_ID \
        --member=serviceAccount:SERVICE_ACCOUNT_EMAIL_ADDRESS \
        --role=roles/run.builder

    PROJECT_ID 替换为您的 Google Cloud项目 ID,并将 SERVICE_ACCOUNT_EMAIL_ADDRESS 替换为 Cloud Build 服务账号的邮箱。如果您使用 Compute Engine 默认服务账号作为 Cloud Build 服务账号,则服务账号邮箱应采用以下格式:

    PROJECT_NUMBER-compute@developer.gserviceaccount.com

    PROJECT_NUMBER 替换为您的 Google Cloud项目编号。

    如需详细了解如何查找项目 ID 和项目编号,请参阅创建和管理项目

    授予 Cloud Run Builder 角色之后,需要几分钟时间才能完成传播

    编写示例函数

    如需编写应用,请按照以下步骤操作:

    Node.js

    1. 创建名为 helloworld 的新目录,并转到此目录中:

         mkdir helloworld
         cd helloworld
      

    2. helloworld 目录中创建一个 package.json 文件以指定 Node.js 依赖项:

      {
        "name": "nodejs-docs-samples-functions-hello-world-get",
        "version": "0.0.1",
        "private": true,
        "license": "Apache-2.0",
        "author": "Google Inc.",
        "repository": {
          "type": "git",
          "url": "https://github.com/GoogleCloudPlatform/nodejs-docs-samples.git"
        },
        "engines": {
          "node": ">=16.0.0"
        },
        "scripts": {
          "test": "c8 mocha -p -j 2 test/*.test.js --timeout=6000 --exit"
        },
        "dependencies": {
          "@google-cloud/functions-framework": "^3.1.0"
        },
        "devDependencies": {
          "c8": "^10.0.0",
          "gaxios": "^6.0.0",
          "mocha": "^10.0.0",
          "wait-port": "^1.0.4"
        }
      }
      
    3. 使用以下 Node.js 示例在 helloworld 目录中创建一个 index.js 文件:

      const functions = require('@google-cloud/functions-framework');
      
      // Register an HTTP function with the Functions Framework that will be executed
      // when you make an HTTP request to the deployed function's endpoint.
      functions.http('helloGET', (req, res) => {
        res.send('Hello World!');
      });

    Python

    1. 创建名为 helloworld 的新目录,并转到此目录中:

         mkdir helloworld
         cd helloworld
      

    2. helloworld 目录中创建一个 requirements.txt 文件,以指定 Python 依赖项:

      functions-framework==3.9.2
      flask==3.0.3
      google-cloud-error-reporting==1.11.1
      MarkupSafe==2.1.3
      

      这会添加示例所需的软件包。

    3. 使用以下 Python 示例在 helloworld 目录中创建一个 main.py 文件:

      import functions_framework
      
      @functions_framework.http
      def hello_get(request):
          """HTTP Cloud Function.
          Args:
              request (flask.Request): The request object.
              <https://flask.palletsprojects.com/en/1.1.x/api/#incoming-request-data>
          Returns:
              The response text, or any set of values that can be turned into a
              Response object using `make_response`
              <https://flask.palletsprojects.com/en/1.1.x/api/#flask.make_response>.
          Note:
              For more information on how Flask integrates with Cloud
              Functions, see the `Writing HTTP functions` page.
              <https://cloud.google.com/functions/docs/writing/http#http_frameworks>
          """
          return "Hello World!"
      
      

    Go

    1. 创建名为 helloworld 的新目录,并转到此目录中:

         mkdir helloworld
         cd helloworld
      

    2. 创建 go.mod 文件以声明 go 模块

      module github.com/GoogleCloudPlatform/golang-samples/functions/functionsv2/helloworld
      
      go 1.24.0
      
      require github.com/GoogleCloudPlatform/functions-framework-go v1.8.1
      
      require (
      	github.com/cloudevents/sdk-go/v2 v2.15.2 // indirect
      	github.com/google/go-cmp v0.6.0 // indirect
      	github.com/google/uuid v1.6.0 // indirect
      	github.com/json-iterator/go v1.1.12 // indirect
      	github.com/modern-go/concurrent v0.0.0-20180306012644-bacd9c7ef1dd // indirect
      	github.com/modern-go/reflect2 v1.0.2 // indirect
      	github.com/stretchr/testify v1.10.0 // indirect
      	go.uber.org/multierr v1.11.0 // indirect
      	go.uber.org/zap v1.27.0 // indirect
      	golang.org/x/time v0.9.0 // indirect
      )
      
    3. 使用以下 Go 代码示例在 helloworld 目录中创建一个 hello_http.go 文件:

      
      // Package helloworld provides a set of Cloud Functions samples.
      package helloworld
      
      import (
      	"fmt"
      	"net/http"
      
      	"github.com/GoogleCloudPlatform/functions-framework-go/functions"
      )
      
      func init() {
      	functions.HTTP("HelloGet", helloGet)
      }
      
      // helloGet is an HTTP Cloud Function.
      func helloGet(w http.ResponseWriter, r *http.Request) {
      	fmt.Fprint(w, "Hello, World!")
      }
      

    Java

    1. 创建名为 helloworld 的新目录,并转到此目录中:

         mkdir helloworld
         cd helloworld
      

    2. 创建以下项目结构以包含源目录和源文件:

      mkdir -p ~/helloworld/src/main/java/functions
      touch ~/helloworld/src/main/java/functions/HelloWorld.java
      
    3. 使用以下 Java 代码示例更新 HelloWorld.java 文件:

      
      package functions;
      
      import com.google.cloud.functions.HttpFunction;
      import com.google.cloud.functions.HttpRequest;
      import com.google.cloud.functions.HttpResponse;
      import java.io.BufferedWriter;
      import java.io.IOException;
      
      public class HelloWorld implements HttpFunction {
        // Simple function to return "Hello World"
        @Override
        public void service(HttpRequest request, HttpResponse response)
            throws IOException {
          BufferedWriter writer = response.getWriter();
          writer.write("Hello World!");
        }
      }
    4. helloworld 目录中创建一个 pom.xml 文件,并添加以下 Java 依赖项:

      <?xml version="1.0" encoding="UTF-8"?>

            --source . \
            --function helloGET \
            --base-image nodejs24 \
            --region REGION \
            --allow-unauthenticated
      

      REGION 替换为您要在其中部署函数的服务的 Google Cloud区域。例如 europe-west1

      Python

      gcloud run deploy python-http-function \
            --source . \
            --function hello_get \
            --base-image python313 \
            --region REGION \
            --allow-unauthenticated
      

      REGION 替换为您要在其中部署函数的服务的 Google Cloud区域。例如 europe-west1

      Go

      gcloud run deploy go-http-function \
             --source . \
             --function HelloGet \
             --base-image go125 \
             --region REGION \
             --allow-unauthenticated
      

      REGION 替换为您要在其中部署函数的服务的 Google Cloud区域。例如 europe-west1
