查詢 registor 有哪些鏡像¶
curl -X GET http://127.0.0.1:5000/v2/_catalog
{"repositories":["mytomcat"]}
hyper/docker-registry-web(倉庫 WEB UI )¶
docker run -d -p 5000:5000 --name registry registry:2
docker run -d -p 8080:8080 --name registry-web --link registry -e REGISTRY_URL=http://127.0.0.1:5000/v2 -e REGISTRY_NAME=127.0.0.1:5000 hyper/docker-registry-web
參考文檔.hyper/docker-registry-web¶
docker run -d -p 5000:5000 --name registry-srv registry:2
docker run -it -p 8080:8080 --name registry-web --link registry-srv -e REGISTRY_URL=http://registry-srv:5000/v2 -e REGISTRY_NAME=localhost:5000 hyper/docker-registry-web
