docker run -d -p 5000:5000 -v /opt/registry/data:/var/lib/registry --privileged=true --restart=always --name registry registry:latest

目录：/opt/registry/data

开端口5000

http://IP:5000/v2/

{
  "registry-mirrors": [
    "http://f1361db2.m.daocloud.io"
  ],
  "insecure-registries": [
    "192.172.34.162:5000"
  ],
  "debug": true,
  "experimental": false
}

如果不配置：

 因为Docker与Docker Registry交互默认使用https，然而此处搭建的Docker Registry只提供http服务，所以当和Registry私有仓库交互时会失败，为了解决这个问题需要在启动Docker时配置Registry不安全选项。

Linux

添加如下文件(如果没有，有就修改)，重启Docker，并重启registry容器

vi /etc/docker/daemon.json
{
    "registry-mirrors": [
        "http://68cdf6cf.m.daocloud.io"
    ],
    "insecure-registries":["192.172.34.162:5000"]
}

# systemctl restart docker
# docker start registry

Docker CE没有/etc/docker/daemon.json配置文件。请修改/usr/lib/systemd/system/docker.service

# vi /usr/lib/systemd/system/docker.service
ExecStart=/usr/bin/dockerd --registry-mirror=http://xxxxxxxx.m.daocloud.io  --insecure-registry 192.172.34.162:5000
