基于docker commit命令创建

Docker提供了docker commit命令，支持用户提交自己对定制容器的修改，并生成新的镜像。

命令格式为：docker commit CONTAINER [REPOSITORY[:TAG]]

准备工作

利用ubuntu:14.04镜像创建一个容器：

[root@node1 ~]# docker images
REPOSITORY              TAG                 IMAGE ID            CREATED             SIZE
docker.io/ubuntu        latest              b44d403a0d52        3 days ago          64.2 MB
docker.io/nginx         latest              540a289bab6c        12 days ago         126 MB
docker.io/hello-world   latest              fce289e99eb9        10 months ago       1.84 kB
[root@node1 ~]# 
[root@node1 ~]# docker run -it docker.io/ubuntu /bin/bash
root@b44d403a0d52:/#
