腾讯云云函数SCF组件

 

简介

该组件是serverless-tencent组件库中的基础组件之一。通过云函数SCF组件,可以快速,方便的创建,配置和管理腾讯云的SCF云函数。

快速开始

 

通过SCF组件,对一个云函数进行完整的创建,配置,部署和删除等操作。支持命令如下:

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

 

1. 安装

通过npm安装serverless

$ npm install -g serverless

2. 创建

$ mkdir my-function
$ cd my-function

目录内容如下:

|- code
  |- index.js
|- serverless.yml

对于该例子可以使用一下 Demo,作为 index.js:

'use strict';
exports.main_handler = async (event, context, callback) => {
    console.log("%j", event);
    return "hello world"
};

3. 配置

本地创建 serverless.yml 文件,在其中进行如下配置

$ touch serverless.yml
# serverless.yml
myFunction1:
  component: "@serverless/tencent-scf"
  inputs:
    name: myFunction1
    codeUri: ./code       # 代码目录
    handler: index.main_handler
    runtime: Nodejs8.9
    region: ap-guangzhou
    description: My Serverless Function
    memorySize: 128
    timeout: 20
    # 打包zip时希望忽略的文件或者目录配置(可选)
    exclude:
      - .gitignore
      - .git/**
      - node_modules/**
      - .serverless
      - .env
    include:
          - /Users/dfounderliu/Desktop/temp/.serverless/myFunction1.zip
    environment:
      variables:
        TEST: vale
    vpcConfig:
      subnetId: ''
      vpcId: ''

myFunction2:
  component: "@serverless/tencent-scf"
  inputs:
    name: myFunction2
    codeUri: ./code

4. 部署

如您的账号未登陆注册腾讯云,您可以直接通过微信扫描命令行中的二维码进行授权登陆和注册。

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

5. 移除

$ sls remove --debug

  DEBUG ─ Flushing template state and removing all components.
  DEBUG ─ Removed function myFunction successful

  1s › myFunction › done

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。

# .env
TENCENT_SECRET_ID=123
TENCENT_SECRET_KEY=123

?
