#下载

#启动mysql容器,返回容器id (-p 3306:3306 指定外部连接端口，不指定外部连接不上)
docker run --name gitlab-mysql -e MYSQL_ROOT_PASSWORD=Mimais163. -d mysql
#连接进入mysql命令行
docker run -it --link gitlab-mysql:mysql --rm mysql sh -c 'exec mysql -h"$MYSQL_PORT_3306_TCP_ADDR" -P"$MYSQL_PORT_3306_TCP_PORT" -uroot -p"$MYSQL_ENV_MYSQL_ROOT_PASSWORD"'
#MySQL命令
show databases; #显示数据库
quit #退出命令行

#启动redis容器

sameersbn/gitlab
注 在 Docker 中使用 GitLab

sameersbn/gitlab和gitlab/gitlab-ce区别在于前者需要MySQL和redis,后者集成所有环境
