[email protected]:/home/my_registry#curl -XGET http://0.0.0.0:5000/v2/_catalog
{"repositories":[]}5.修改为符合私服规范的Tag docker tag 镜像ID或镜像名：Tag Host:Port/Repository:Tag
[email protected]:/home/my_registry#docker tag hello:v1 0.0.0.0:5000/hello:v1

[email protected]:/home/my_registry#docker push 0.0.0.0:5000/hello:v1
The push refers to repository [0.0.0.0:5000/hello]
Get "https://0.0.0.0:5000/v2/": http: server gave HTTP response to HTTPS client7.修改docker 配置文件/etc/docker/daemon.json ,如果不存在就创建一个daemon.json
[email protected]:/etc/docker#vi daemon.json
内容如下：
{
"insecure-registries":["0.0.0.0:5000"]
}重启docker
[email protected]:/etc/docker#systemctl restart docker
[email protected]:/etc/docker#docker push 0.0.0.0:5000/hello:v1
The push refers to repository [0.0.0.0:5000/hello]
Get "http://0.0.0.0:5000/v2/": dial tcp 0.0.0.0:5000: connect: connection refused

redis6.28.由于重启docker，导致registry服务关闭需重新启动
[email protected]:/etc/docker#docker run -d -p 5000:5000 -v /home/my_registry/:/tmp/registry --privileged=true registry
