【解决】Error response from daemon: Get "https://xxx.xx.xx.xxx/v2/": x509: certificate signed by unknown

【解决】Error response from daemon: Get "xxx.xx.xx.xxx/v2/": x509: certificate signed by unknown authority

登陆私有harbor时报错如下：

docker login xxx.xx.xx.xxx
Username: xxxx
Password: xxxx

Error response from daemon: Get "https://xxx.xx.xx.xxx/v2/": x509: certificate signed by unknown authority

原因大概是docker默认支持https的协议，而私有库是http的协议。

windows桌面系统可以在Settings->Docker Engine里配置以下代码，xxx.xx.xx.xxx是自己私有库的地址。

{
    "insecure-registries":[
        "xxx.xx.xx.xxx"
    ]
}

mac桌面可以在Preferences–>Docker Engine里配置以下代码，xxx.xx.xx.xxx是自己私有库的地址。

{
    "insecure-registries":[
        "xxx.xx.xx.xxx"
    ]
}

centos系统，可以修改 /etc/docker/daemon.json，也是新增如下代码。

{
    "insecure-registries":[
        "xxx.xx.xx.xxx"
    ]
}

我的windows桌面是配在这里

 配置完后再登录就可以了
