基于上次打包grafana服务，在服务的基础上部署postgres、redis、nginx三个服务，在每增加一个服务时将容器重新打包成镜像。
充分体现了docker的优点：1、跨平台可移植性，按统一标准打包；2、面向应用，优化部署应用；3、版本控制；4、组件复用，组件式搭建；5、共享性，公共的注册服务器。
下面展示操作过程：
1、将镜像到处迁移到其他机器上运行
导出镜像：
导入镜像:
运行容器：
[root@docker-slave-79101 ~]# docker run -d -p 3000:3000 -p 3222:22 centos_grafana:v1 /usr/local/promethues/grafana-7.1.5/bin/grafana-server
