下载registry

registry是Docker官方提供的仓库镜像
拉取镜像，不指定版本默认拉取最新版本镜像。

docker pull registry
Using default tag: latest
latest: Pulling from library/registry

Status: Downloaded newer image for registry:latest
docker.io/library/registry:latest

当前最新版本2.8.3

运行registry

后台运行，重启机器自启，数据挂在宿主机/data/registry目录。

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

通过浏览器访问私有仓库，现在仓库里面没有镜像，列表是空的。

推送镜像

本机打标签推送到私有仓库里

docker tag shuai:v1.0.0 127.0.0.1:5000/shuaibi:1.0
docker push 127.0.0.1:5000/shuaibi:1.0
The push refers to repository [127.0.0.1:5000/shuaibi]
5f70bf18a086: Pushed

再回到浏览器刷新

其它机器推送到私有仓库

在其它机器上编辑daemon.json文件，没有可以就创建

vi /etc/docker/daemon.json 

添加以下信息

{"insecure-registries":["192.168.170.111:5000"]
}

果有DNS服务器，可以将私有仓库解析个域名这里直接指定域名

{"insecure-registries":["hub.monster.com:5000"]
}

接着加载daemon文件，重启docker

systemctl daemon-reload
systemctl restart docker

推送镜像到私有仓库去

[root@ceshi ~]# docker tag dengchuanfu/chatgpt-next-web:latest hub.monster.com:5000/chatgpt:1.0
[root@ceshi ~]# docker push hub.monster.com:5000/chatgpt:1.0
The push refers to repository [hub.monster.com:5000/chatgpt]

请求一下私有仓库，可以看到列表多了个chatgpt

[root@ceshi ~]# curl -XGET http://hub.monster.com:5000/v2/_catalog
{"repositories":["chatgpt","shuaibi"]}
[root@ceshi ~]# 

想查看镜像的版本号，可以如下请求查看，刚才我又上传了个1.1

[root@ceshi ~]# curl -XGET http://hub.monster.com:5000/v2/chatgpt/tags/list
{"name":"chatgpt","tags":["1.0","1.1"]}
[root@ceshi ~]# 

从私有仓库下载镜像

和公用仓库拉取镜像一样，在需要的镜像前面加上私有仓库地址即可（前提私有仓库有你要的镜像）

[root@ceshi ~]# docker pull hub.monster.com:5000/chatgpt:1.1
1.1: Pulling from chatgpt
