dockerhub 搜索registry
https://hub.docker.com/_/registry
官網文檔
deploy registry server
https://docs.docker.com/registry/deploying/
你可以自己get.docker.com 下一個，但是中國的網絡安裝至少需要若干小時，所以老子選擇
https://labs.play-with-docker.com/
用docker 的id 登錄，然後可以獲取4小時的虛擬機，對於實驗來說足夠了
來來來，下一個repo 託管容器
#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
#進目錄看看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 我感覺就是吃飽了撐的
docker pull localhost:5000/hello-world
docker images
找到一個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
#請注意register爲local repo，registry爲web ui
#眼睛一閉開始下載
#docker rmi konradkleine/docker-registry-frontend:v2
到界面找mapping出來的端口，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
