①下载 registry 镜像

docker pull registry

②指定镜像仓库地址

vim /etc/docker/daemon.json
{
  "insecure-registries": ["192.168.78.11:5000"],		'//添加此段，本机IP地址'
  "registry-mirrors": ["https://********.mirror.aliyuncs.com"]
}


systemctl restart docker.service

③创建 registry 容器并开放端口

docker create -it registry /bin/bash

docker start b8e64eefc883

docker run -d -p 5000:5000 -v /data/registry:/tmp/registry registry
'//-p指定端口，一内一外；-v表示挂载，前者是宿主机，后者是容器'

④给镜像打标签后上传

docker tag nginx:latest 192.168.78.11:5000/nginx

docker push 192.168.78.11:5000/nginx

⑤获取私有仓库列表查看是否上传成功

curl -XGET http://192.168.78.11:5000/v2/_catalog

'//若成功会返回以下值'
{"repositories":["nginx"]}

⑥从私有仓库下载镜像

docker images 

 docker rmi 192.168.78.11:5000/nginx:latest nginx:latest 

docker images 

docker pull 192.168.78.11:5000/sshd

 docker images
