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
