前言

搭建的 harbor 仓库为 http 协议，在本地登录时出现如下报错：

复制代码

docker login http://192.168.xx.xx
Username: admin
Password:
Error response from daemon: Get "https://192.168.xx.xx/v2/": dialing 192.168.xx.xx:443 matches static system exclude: connecting to 192.168.xx.xx:443: dial tcp 192.168.xx.xx:443: connect: connection refused

docker login http://192.168.xx.xx:80
Username: admin
Password:
Error response from daemon: Get "https://192.168.xx.xx:80/v2/": http: server gave HTTP response to HTTPS client

解决方法

修改 /etc/docker/daemon.json，添加 "insecure-registries"

复制代码

{
  "builder": {
    "gc": {
      "defaultKeepStorage": "20GB",
      "enabled": true
    }
  },
  "experimental": false,
  "insecure-registries": ["http://192.168.xx.xx:80"],  // 新增这一行
  "registry-mirrors": [
    "https://1nj0zren.mirror.aliyuncs.com",
    "https://docker.mirrors.ustc.edu.cn",
    "http://f1361db2.m.daocloud.io",
    "https://registry.docker-cn.com"
  ]
}

再次尝试登录

复制代码

docker login http://192.168.58.139:80
