解决报错Error response from daemon: Get https://10.0.0.110/v2/: dial tcp 10.0.0.110:443: connect: connection refused

1.因为docker的访问必须是HTTPS，http是不被信任的。所以无法认证；解决方法如下；
添加--insecure-registry 10.0.0.110

[root@harbor-master-22 harbor]# vim /lib/systemd/system/docker.service 
ExecStart=/usr/bin/dockerd -H fd:// --insecure-registry 10.0.0.110 --containerd=/run/containerd/containerd.sock

2.重启docker后测试；

[root@harbor-master-22 harbor]# systemctl daemon-reload && systemctl restart docker
