首先添加一个镜像加速
##注意分隔符
vim /etc/docker/daemon.json
"registry-mirrors": ["https://8auvmfwy.mirror.aliyuncs.com"]
1.拉取最新镜像
docker pull registry
2.将registry镜像运行并生成一个容器
docker run -d -v /opt/registry:/var/lib/registry -p 5000:5000 --restart=always --name registry registry:latest
-v 参数本地挂载到/opt/registry中
3.因为我们启动的registry服务不是安全可信赖的。这时需要修改客户端docker的配置文件/etc/docker/daemon.json
##集群中要用到私仓的都要修改
"registry-mirrors": [ "https://pee6w651.mirror.aliyuncs.com"],"insecure-registries": ["192.168.26.130:5000"]
https://pee6w651.mirror.aliyuncs.com 为国内镜像仓代理，
192.168.26.130:5000 为registry启动的机器ip
重启docker生效
systemctl restart docker
命令查看
curl -XGET http://192.168.26.130:5000/v2/_catalog
4.搭建完成，开始测试
