执行登录命令：docker login -uadmin 192.168.43.106:8880

报错：

Error response from daemon: Get "https://192.168.43.106:8880/v2/": http: server gave HTTP response to HTTPS client

原因是我们docker client使用的是https，而我们搭建的Harbor私库用的是http的，所以会有这样的报错，导致访问不了。

解决办法： vim /etc/docker/daemon.json

"insecure-registries":["192.168.43.106:8880"], # 添加docker信任地址

systemctl daemon-reload

systemctl restart docker

#### 注意：出现如下报错大概率是地址写错了！###

Error response from daemon: Get "http://192.168.43.105:8880/v2/": Get "http://192.168.3.106:8880/service/token?account=admin&client_id=docker&offline_token=true&service=harbor-registry": dial tcp 192.168.3.106:8880: i/o timeout

是ip地址写错了，坑爹呀！

docker-compose down -v

./prepare

docker-compose up -d
