docker中如何运行shell命令呢?

docker中运行shell的方法

使用docker exec -it containerId bash
    即可为docker开启一个shell session客户端
	并可运行相应的命令

[root@node0 ~]# echo "java265.com"
java265.com
[root@node0 ~]# docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS                             PORTS                                                               NAMES
