操作场景

该模板可以快速部署一个基于 Vue + Express + PostgreSQL 的全栈 Serverless 应用。主要包含以下组件：

  • Serverless RESTful API：通过云函数和 API 网关构建的 Express 框架实现 RESTful API。
  • Serverless 静态网站：前端通过托管 Vue.js 静态页面到 COS 对象存储中。
  • PostgreSQL Serverless：通过创建 PostgreSQL DB 为全栈网站提供数据库服务。
  • VPC：通过创建 VPC 和 子网，提供 SCF 云函数和数据库的网络打通和使用。

操作步骤

安装

通过 npm 全局安装 Serverless CLI：

$ npm install -g serverless

配置

1.新建一个本地文件夹，使用create --template-url命令，下载相关 template。

serverless create --template-url https://github.com/yugasun/tencent-serverless-demo/tree/master/fullstack-serverless-db
$ touch .env # 腾讯云的配置信息

2.在项目模板中找到.env.example文件，修改名称为.env，并在其中配置对应的腾讯云 SecretId 和 SecretKey 信息和地域可用区等信息。

# .env
TENCENT_SECRET_ID=xxx
TENCENT_SECRET_KEY=xxx

# 地域可用区配置
REGION=ap-beijing
ZONE=ap-beijing-3

?

  • 如果没有腾讯云账号，请先 注册新账号。

  • 如果已有腾讯云账号，可以在 API 密钥管理 中获取 SecretId 和 SecretKey。

    3.通过执行以下命令，安装所需依赖：

$ npm run bootstrap

部署

通过sls命令进行部署，并可以添加--debug参数查看部署过程中的信息：

?sls是serverless命令的简写。
