私有資源庫

docker-registry

取得官方 registry 映像檔

docker run -d -p 5000:5000 --restart=always --name registry registry

執行指令啟動後，服務會放在本機 127.0.0.1:5000

標記映像檔

映像檔規則為 <主機名>/<資源庫:版本號>，所以必須將目前的映像檔標記改為 127.0.0.1:5000/ubuntu1804docker:0.2

docker tag kejyun/ubuntu1804docker:0.2 127.0.0.1:5000/ubuntu1804docker:0.2

上傳映像檔到本地端資源庫

$ docker push <主機名>/<資源庫:版本號>

$ docker push 127.0.0.1:5000/ubuntu1804docker

$ docker push 127.0.0.1:5000/ubuntu1804docker

The push refers to repository [127.0.0.1:5000/ubuntu1804docker]
