docker启动registry镜像服务

docker pull registry:2.7.1
mkdir -p /var/docker/registry/data
docker run -d -v /var/docker/registry/data:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:2.7.1

编辑docker daemon文件，允许使用http方式访问自定义的镜像服务

vi /etc/docker/daemon.json

{
  "registry-mirrors": ["https://.mirror.aliyuncs.com"],
  "insecure-registries":["192.168.190.126:5000"]
 
}

重启docker

systemctl restart docker
