问题：搭建私库认证不通过x509: certificate signed by unknown authority

首先确保配置harbor私库地址

[root@master harbor]# grep hostname  harbor.cfg 
#The IP address or hostname to access admin UI and registry service.
hostname = hub.bingo.com

方法一：/etc/docker/daemon.json，添加私库地址

{
     
   "insecure-registries":["私库地址"]
}

方法二：vim /usr/lib/systemd/system/docker.service

ExecStart=/usr/bin/dockerd  --insecure-registry 私库地址

[root@master data]# systemctl daemon-reload
[root@master data]# systemctl restart docker
[root@master data]# docker info
修改完成后输入，doucker info查看下
