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
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See

Login Succeeded

# 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

2、运行私有库registry，相当于本地有个私有docker hub。

docker run -d -p 5000:5000 -v /yoyo/myregistry/:/tmp/registry --privileged=true registry

3、制作一个带有ifconfig的Ubuntu镜像

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

#docker run -it ba6acccedd29
root@32e09b37ba40:/# apt-get update 
root@32e09b37ba40:/# apt-get install net-tools -y

root@32e09b37ba40:/# ifconfig 
eth0: flags=4163<UP,BROADCAST,RUNNING,MULTICAST>  mtu 1500
        inet 172.17.0.3  netmask 255.255.0.0  broadcast 172.17.255.255
        inet6 fe80::42:acff:fe11:3  prefixlen 64  scopeid 0x20<link>
        ether 02:42:ac:11:00:03  txqueuelen 0  (Ethernet)
        RX packets 8745  bytes 31390066 (31.3 MB)
        RX errors 0  dropped 0  overruns 0  frame 0
        TX packets 4426  bytes 243881 (243.8 KB)
        TX errors 0  dropped 0 overruns 0  carrier 0  collisions 0
再使用快捷键 Ctrl+p+q退出，容器继续在后台运行。

# docker ps
CONTAINER ID   IMAGE          COMMAND                   CREATED         STATUS         PORTS                                       NAMES
32e09b37ba40   ba6acccedd29   "bash"                    7 minutes ago   Up 7 minutes    
# docker commit -m="ifconfig cmd add" -a="yoyo" 32e09b37ba40 ifubuntu:3.24
sha256:f53ed00a420725a04c8ba4314c8cf839e640d79df898b4539d60c442d59a6975

4、curl验证私有仓库有什么镜像

# curl -XGET http://192.168.80.172:5000/v2/_catalog
{"repositories":[]}

5、将镜像修改符合私有库规范的tag

# docker images
REPOSITORY   TAG       IMAGE ID       CREATED         SIZE
ifubuntu     3.24      f53ed00a4207   2 minutes ago   124MB
# docker tag ifubuntu:3.24 192.168.80.172:5000/ifubuntu:3.24
# docker images
REPOSITORY                     TAG       IMAGE ID       CREATED         SIZE
192.168.80.172:5000/ifubuntu   3.24      f53ed00a4207   3 minutes ago   124MB

6、修改配置文件使之支持http

# vim /etc/docker/daemon.json

, "insecure-registries":["192.168.80.172:5000"]  #重点逗号


#重启docker

7、push推送到私服库

# docker run -d -p 5000:5000 -v /yoyo/myregistry/:/tmp/registry --privileged=true registry
7cc7789c511f09f713993ee11e22dbb79a08ef00f1138f124610d2a19b4c221c
#重新启用私服库

# docker push 192.168.80.172:5000/ifubuntu:3.24
The push refers to repository [192.168.80.172:5000/ifubuntu]
cc42a815d1b0: Pushed 
9f54eef41275: Pushed 
3.24: digest: sha256:c58ea58f4c35f4ea8bd139bd5a9b3bdc8cc9a497abf581d2e50847ea419eb8b6 size: 741
 

8、再次curl验证私服库有什么镜像

# curl -XGET http://192.168.80.172:5000/v2/_catalog
{"repositories":["ifubuntu"]}

9、pull到本地并运行

#docker images
