一、制作一个简单的Ubuntu中安装vim的镜像

docker pull ubuntu
docker images
REPOSITORY    TAG       IMAGE ID       CREATED         SIZE
ubuntu        latest    ba6acccedd29   2 years ago     72.8MB

docker run -it ubuntu
root@8b9f2522faa0:/# apt-get update   #先更新一下软件包列表
root@8b9f2522faa0:/# apt-get install vim -y
root@8b9f2522faa0:/# echo "hello world" > abc.tec    #随便添加一点信息
root@8b9f2522faa0:/# cat abc.tec 
hello world

按下Ctrl+p+q退出容器，容器不停止（如果直接使用exit，容器会停止运行，这样就不能制作镜像了）

# docker ps

CONTAINER ID   IMAGE     COMMAND   CREATED         STATUS         PORTS     NAMES

# docker commit -m="ubuntu add vim"  -a="haha" 8b9f2522faa0  ubuntuvim:3.23

# docker images                                     #查看制作好的镜像
REPOSITORY    TAG       IMAGE ID       CREATED          SIZE
ubuntuvim     3.23      761b629328e8   56 seconds ago   191MB

二、在阿里云上面创建镜像仓库

 

三、从阿里云仓库中上传和拉取镜像

直接复制示例中的代码

# docker login --username=aliyun8035446320 registry.cn-hangzhou.aliyuncs.com
