sqler sql 转rest api 的docker 镜像构建（续）使用源码编译

sqler 在社区的响应还是很不错的，已经添加了好多数据库的连接，就在早上项目的包管理还没有写明确，
下午就已经有go mod 构建的支持了，同时也调整下docker 镜像的构建，直接使用git clone + go mod

备注： go mod 是新的包管理方案，需要新版本的golang，使用容器就不存在这个问题了，同时对于国内
还有一个墙的问题,同时我push了1.7tag 的镜像，就是使用go mod 构建的。

默认配置

config.example.hcl： 这个我有些调整，实际自己修改

​

}

​

demo {

​

}

 

 

entrypoiny 文件

#!/bin/sh

sqler -driver ${DRIVER} -rest ${REST} -dsn ${DSN} -config ${CONFIG} -workers ${WORKERS} -resp ${RESP}

 

使用

docker-compose文件

version: "3"

services:

  sqler:

    image: dalongrong/sqler:1.7

    volumes:

    - "./config/config.example.hcl:/app/config.example.hcl"

    environment:

    - "DSN=root:dalongrong@tcp(mysqldb:3306)/test?multiStatements=true"

    ports:

    - "3678:3678"

    - "8025:8025"

  mysqldb:

    image: mysql:5.7.16

    ports:

      - 3306:3306

    command: --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci

    environment:

      MYSQL_ROOT_PASSWORD: dalongrong

      MYSQL_DATABASE: test

      MYSQL_USER: test

      MYSQL_PASSWORD: test

      TZ: Asia/Shanghai

说明

对于墙的问题，我们可以使用dockerhub 托管的构建，对于需要调试代码的，合理上网解决吧
