docker file
容器变为镜像创建这个镜像
# docker create --name myxudong -it docker.io/java /bin/bash
98d030d2271ed262904af36e115f07dd5ea56fca2a1d7cf02ffed816fbdd7a96
进入这个镜像，在容器内创建文件
# docker exec -it98d030d2271e /bin/bash
root@98d030d2271e:/# mkdir xudong
root@98d030d2271e:/# ls
bin bootdevetc homeliblib64 mediamntopt procrootrun sbinsrvsys tmpusrvar xudong
root@98d030d2271e:/# exit
exit
将容器变成镜像为：bathroom
# docker commit98d030d2271e bathroom
068bfde81f1e87930eae4f7b07f3e3c65fd6ec4a04eec06f2781d1f14ec7a75f
运行bathroom 这个容器进程查看。发现有:xudong这个文件。
# docker run -it bathroomls
