docker push "server gave HTTP response to HTTPS client"问题解决方案

docker push 镜像到本地镜像仓库时报如下错误:

[root@master registry]# docker push 172.20.120.211:32002/harbor-log
The push refers to a repository [172.20.120.211:32002/harbor-log]
Get https://172.20.120.211:32002/v1/_ping: http: server gave HTTP response to HTTPS client

解决办法是：

在/etc/docker下，修改daemon.json文件，写入：

{"insecure-registries":["172.20.120.211:32002"]}

重启docker

[root@master docker]# systemctl restart docker.service

重新启动registry。

docker push 成功。
