dockerfile 指定镜像源拉取镜像 docker拉取镜像到本地

7、push推送到私服库

8、再次curl验证私服库有什么镜像

9、pull到本地并运行

---

一、上次到阿里云服务器

1、制作一个带有vim功能的Ubuntu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
8b9f2522faa0   ubuntu    "bash"    5 minutes ago   Up 5 minutes             optimistic_wescoff

# docker commit -m="ubuntu add vim"  -a="haha" 8b9f2522faa0  ubuntuvim:3.23    
sha256:761b629328e8fb5ae1cd187d5a1b0c5f12107bcad6663b1cf8b89c93e5f5201a

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

2、在阿里云上面创建镜像仓库

3、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

# docker images
REPOSITORY    TAG       IMAGE ID       CREATED          SIZE
ubuntuvim     3.23      761b629328e8   11 minutes ago   191MB
# docker tag 761b629328e8 registry.cn-hangzhou.aliyuncs.com/yoyo_chengdu/ubuntu:3.23

# docker push registry.cn-hangzhou.aliyuncs.com/yoyo_chengdu/ubuntu:3.23
The push refers to repository [registry.cn-hangzhou.aliyuncs.com/yoyo_chengdu/ubuntu]
af91d09903b5: Pushed

# docker rmi -f 761b629328e8      #删除制作的镜像

# docker pull registry.cn-hangzhou.aliyuncs.com/yoyo_chengdu/ubuntu:3.23 #拉取镜像

# docker images
REPOSITORY                                              TAG       IMAGE ID       CREATED          SIZE
registry.cn-hangzhou.aliyuncs.com/yoyo_chengdu/ubuntu   3.23      761b629328e8   16 minutes ago   191MB

# docker run -it 761b629328e8
root@2fb3a6485a7f:/# cat abc.tec 
hello world           #查看信息是否还在

二、上传镜像到本地私有库registry

1、下载镜像docker registry

# docker pull registry
