简介

腾讯云 Egg.js Serverless Component。

目录

  1. 准备
  2. 安装
  3. 配置
  4. 部署
  5. 移除

0. 准备

初始化 Egg 项目

$ mkdir egg-example && cd egg-example
$ npm init egg --type=simple
$ npm i

修改 Egg 配置

由于云函数在执行时,只有 /tmp 可读写的,所以我们需要将 egg.js 框架运行尝试的日志写到该目录下,为此需要修改 config/config.default.js 中的配置如下:

const config = (exports = {
  env: 'prod', // 推荐云函数的 egg 运行环境变量修改为 prod
  rundir: '/tmp',
  logger: {
    dir: '/tmp'
  }
})

1. 安装

通过 npm 全局安装 serverless cli

$ npm install -g serverless

2. 配置

在项目根目录创建 serverless.yml 文件,在其中进行如下配置

$ touch serverless.yml
# serverless.yml

MyComponent:
  component: '@serverless/tencent-egg'
  inputs:
    region: ap-guangzhou
    functionName: egg-function
    runtime: Nodejs8.9
    code: ./
    functionConf:
      timeout: 10
      memorySize: 128
      environment:
        variables:
          TEST: vale
      vpcConfig:
        subnetId: ''
        vpcId: ''
    apigatewayConf:
      protocols:
        - https
      environment: release

4. 移除

通过以下命令移除部署的 Egg 服务资源,包括云函数和 API 网关。

$ sls remove --debug

  DEBUG ─ Flushing template state and removing all components.
  DEBUG ─ Removed function egg-function successful
  DEBUG ─ Removing any previously deployed API. api-et0yjwci
  DEBUG ─ Removing any previously deployed service. service-jkcevoqw

账号配置(可选)

当前默认支持 CLI 扫描二维码登录,如您希望配置持久的环境变量/秘钥信息,也可以本地创建 .env 文件

$ touch .env # 腾讯云的配置信息

.env 文件中配置腾讯云的 SecretId 和 SecretKey 信息并保存

如果没有腾讯云账号,可以在此 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 SecretIdSecretKey.

# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123

注意!!!

通常初始化的 egg 项目,会自动创建 app/public 目录。但是在打包压缩时,如果该目录为空,则部署后,该目录不会存在。所以 egg 项目启动时会自动创建,但是云函数是没有操作权限的,建议可以在 app/public 目录下创建一个空文件 .gitkeep,来解决此问题。

可以在 Serverless Components repo 中查询更多组件的信息。

常见问题解答

  1. 部署时一直处于打包压缩阶段
