docker根据容器创建镜像
创建一个镜像，执行里面的mengka.sh
1. 根据已经存在的镜像，创建容器
sh-3.2# docker run -ti ubuntu:mengka
root@9b56cabcf039:/# ls
binbootdevetchomeliblib64mediamntoptprocrootrunsbinsrvsystmpusrvar
2. 在容器中，新建脚本
vi mengka.sh
#!/bin/bash
while true;do echo `date +%F%T`;sleep 1;done
每秒打印一次当前时间；
root@9b56cabcf039:/# ls
binbootdevetchomeliblib64mediamengka.shmntoptprocrootrunsbinsrvsystmpusrvar
3. 根据刚刚退出的容器，创建一个镜像
sh-3.2# docker ps -a

4. 利用刚刚创建的镜像，创建一个容器
docker run -d mengka-image-time01 /bin/sh mengka.sh
sh-3.2#docker run -d mengka-image-time01 /bin/sh mengka.sh
