The push refers to a repository [192.168.43.65/library/nginx]
Get https://192.168.43.65/v1/_ping: dial tcp 192.168.43.65:443: getsockopt: connection refused
解决：
能登录成功但是无法上传镜像， 是因为harbor的端口是5000， 没有用原来的80端口，所以需要tag镜像的时候加上5000端口再push
[root@bogon harbor]# docker tag 192.168.43.65/library/nginx:latest 192.168.43.65:5000/library/nginx/latest
