2、运行私有库registry，相当于本地有个私有docker hub。
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

# docker images #查看制作好的镜像

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

# 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

# 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 registry2、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 registry3、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

再使用快捷键 Ctrl+p+q退出，容器继续在后台运行。
# docker ps

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]

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
