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。

entrypoiny 文件

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:

mysqldb:
image: mysql:5.7.16
ports:

environment:
MYSQL_ROOT_PASSWORD: dalongrong
MYSQL_DATABASE: test
MYSQL_USER: test

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
