13.运行一个新容器，同时为它命名、端口映射、文件夹映射。以redmine镜像为例
docker run --name redmine -p 9003:80 -p 9023:22 -d -v /var/redmine/files:/redmine/files -v/var/redmine/mysql:/var/lib/mysql sameersbn/redmine
14. 一个容器连接到另一个容器&sonar容器连接到mmysql容器，并将mmysql容器重命名为db。这样，sonar容器就可以使用db的相关的环境变量了。
run -i -t --name sonar -d -link mmysql:dbtpires/sonar-server
15. 当需要把一台机器上的镜像迁移到另一台机器的时候，需要保存镜像与加载镜像
docker save > /home/aa.tar
16.拷贝文件到另一机器
scp -r /home/aa.tar root@192.168.1.65:/home/aa.tar
17.加载打包好的镜像
docker load < /home/aa.tar
18.构建自己的镜像
docker build -t <镜像名> <镜像文件路径>
eg：docker build -t aa /home/aa.tar
