倉庫是集中存放鏡像的地方

註冊服務器是存放倉庫的服務器，每個服務器上有多個倉庫

搜索鏡像

docker search ubuntu

從docker hub的ubuntu倉庫下載ubuntu鏡像

docker pull ubuntu

安裝docker-distribution

yum install -y docker-distribution

啟動服務並開機自啟

systemctl enable docker-distribution

systemctl start docker-distribution

或

通過官方提供的registry鏡像創建私有倉庫

docker run -d -p 5000:5000 -v /data/registry:/var/lib/registry registry

-v把registry的容器路徑/var/lib/registry映射到本機的 /data/registry

私有倉庫IP為 192.168.200.102

上傳鏡像到私有倉庫

標記鏡像為192.168.200.102:5000/ubuntu:16.04.3

docker tag ubuntu:16.04.3 192.168.200.102:5000/ubuntu:16.04.3

docker images

REPOSITORY TAG IMAGE ID CREATED SIZE

192.168.200.102:5000/ubuntu 16.04.3 747cb2d60bbe 11 days ago 122 MB

ubuntu 16.04.3 747cb2d60bbe 11 days ago 122 MB

上傳鏡像

docker push 192.168.200.102:5000/ubuntu:16.04.3

如出現報錯

The push refers to a repository [192.168.200.102:5000/ubuntu]

Get https://192.168.200.102:5000/v1/_ping: http: server gave HTTP response to HTTPS client

docker client創建daemon.json文件

vim /etc/docker/daemon.json

{ "insecure-registries":["192.168.200.102:5000"] }

systemctl restart docker

驗證

curl http://192.168.200.102:5000/v2/_catalog

{"repositories":["ubuntu"]}

curl http://192.168.200.102:5000/v2/ubuntu/tags/list

{"name":"ubuntu","tags":["16.04.3"]}
