将Golang应用部署到Docker

三、重新构建镜像

重复先前的步骤，回到 gin-blog 的项目根目录下执行 docker build -t blog .

四、创建并运行一个新容器

关联

Q：我们需要将 Golang 容器和 Mysql 容器关联起来，那么我们需要怎么做呢？

A：增加命令 --link dockermysql:mysql 让 Golang 容器与 Mysql 容器互联；通过 --link，可以在容器内直接使用其关联的容器别名进行访问，而不通过IP，但是--link只能解决单机容器间的关联，在分布式多机的情况下，需要通过别的方式进行连接

运行

执行命令 docker run --link dockermysql:mysql -p 8080:8080 blog

$ docker run --link dockermysql:mysql -p 8080:8080 blog
[GIN-debug] [WARNING] Running in "debug" mode. Switch to "release" mode in production.
 - using env:	export GIN_MODE=release
 - using code:	gin.SetMode(gin.ReleaseMode)
...
Actual pid is 1

结果

检查启动输出、接口测试、数据库内数据，均正常；我们的 Golang 容器和 Mysql 容器成功关联运行，大功告成 :)
