登录后创建Blob Stores(docker MyDockerBlobStores)

 创建docker host（可以push/pull）

 docker 代理仓库，可以是docker中央仓库也可以是阿里云仓库，也可创建多个代理仓库，只能pull

 dock组（只能pull）

 如果push 会报异常

　坑

1.仓库端口需要映射出来

 2.http 访问群晖docker 配置

/var/packages/Docker/etc

修改dockerd.json：
vim dockerd.json 

{
   "data-root" : "/var/packages/Docker/target/docker",
   "log-driver" : "db",
   "registry-mirrors" : ["https://registry.docker-cn.com"],
   "storage-driver" : "btrfs",
   "insecure-registries" : ["http://192.168.231.3:9081","http://192.168.231.3:9082","http://192.168.231.3:9083"],
   "hosts": ["unix:///var/run/docker.sock", "tcp://0.0.0.0:2375"]
}

这http访问配置

"insecure-registries" : ["http://192.168.231.3:9081","http://192.168.231.3:9082","http://192.168.231.3:9083"]

不知道为啥我用本地ip访问一直超时

root@JD-NAS:/var/packages/Docker/etc# docker login 192.168.231.3:9082
Username: admin
Password:
Error response from daemon: Get "http://192.168.231.3:9082/v2/": net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

所以我配置了hosts

vim /etc/hosts

root@JD-NAS:/var/packages/Docker/etc# docker login JD-NAS:9081 -u admin -p 123456

打包nginx

docker tag nginx:latest JD-NAS:9081/nginx:latest

root@JD-NAS:/var/packages/Docker/etc# docker push JD-NAS:9081/nginx
