docker 搭建registry(使用docker-ce新版本搭建)

使用docker-ce新版本搭建。不要使用docker   yum install docker   13ba

docker-ce docker-ee在17年  分为两个分支发布

[root@host-192-168-215-50~]docker run -d -v /opt/registry:/var/lib/registry -p 4000:5000 --restart=always --name registry registry

私有仓库搭建在192.168.215.50:4000

[root@host-192-168-215-50 yum.repos.d]# curl -XGET http://192.168.215.50:4000/v2/_catalog

{"repositories":["commitnginx","some-content-nginx","testnginx"]}

[root@host-192-168-215-36 ~]vim /usr/lib/systemd/system/docker.service

# ExecStart=/usr/bin/dockerd
ExecStart=/usr/bin/dockerd --insecure-registry 192.168.10.139:4000

[root@host-192-168-215-36 ~]
