dockerhub 搜索registry
https://hub.docker.com/_/registry
官网文档
deploy registry server
https://docs.docker.com/registry/deploying/
你可以自己get.docker.com 下一个，但是中国的网络安装至少需要若干小时，所以老子选择
https://labs.play-with-docker.com/
用docker 的id 登录，然后可以获取4小时的虚拟机，对于实验来说足够了
来来来，下一个repo 托管容器
#download registry image
docker run -d -p 5000:5000 --restart always --name register registry:2
秒下成功
#download hello-world image
docker pull hello-world
#下好了
docker ps -a
#tag & push image to local repostory
docker tag hello-world localhost:5000/hello-world
docker push localhost:5000/hello-world
#进目录看看image
docker exec -it register /bin/sh
goto /var/lib/registry/ , you can found all the images
#remove docker image
docker rmi hello-world
#download images from local repo 我感觉就是吃饱了撑的
docker pull localhost:5000/hello-world
docker images
找到一个docker repo的web ui
https://hub.docker.com/r/konradkleine/docker-registry-frontend
docker run \
-d \
-e ENV_DOCKER_REGISTRY_HOST=registry \
-e ENV_DOCKER_REGISTRY_PORT=5000 \
-p 8080:80 \
--link register:registry \
konradkleine/docker-registry-frontend:v2
#请注意register为local repo，registry为web ui
#眼睛一闭开始下载
#docker rmi konradkleine/docker-registry-frontend:v2
到界面找mapping出来的端口，8080是docker repo的web ui，5000是repo的端口
found the hello world image
#tag & push a new image 更新了v2到v3
docker tag konradkleine/docker-registry-frontend:v2 localhost:5000/konradkleine/docker-registry-frontend:v3
docker push localhost:5000/konradkleine/docker-registry-frontend:v3
refresh repo web ui
