docker登录harbor、K8s拉取镜像报http: server gave HTTP response to HTTPS client

当搭建完docker私有仓库后，准备docker login http://ip:端口 登录时会包如下错误

当我们使用docker私有仓库中的镜像在K8s集群中部署应用时会包如下错误

以上错误根据报错信息可以知道，不能使用不安全的http协议连接远程仓库。一种方式是使用https协议进行访问，但需要我们在docker客户端维护好证书；另一种方式是在insecure-registries配置项中设置仓库地址，允许访问远程仓库

在linux中设置docker insecure-registries

• vim /etc/docker/daemon.json 在insecure-registries配置项中添加私有仓库地址

{"insecure-registries": ["http://172.17.13.1:5000"],"builder": {"gc": {"enabled": true,"defaultKeepStorage": "20GB"}},"registry-mirrors": ["https://6kx4zyno.mirror.aliyuncs.com"],"features": {"buildkit": true},"experimental": false
}

• 重启docker使配置生效

systemctl daemon-reload
systemctl restart docker

在mac中设置docker insecure-registries

mac中安装的docker使用图形化界面管理，可以通过如下步骤设置

• 打开Preferences菜单，选择Docker Engine，配置insecure-registries。修改完成后，点击apply & Restart完成
  

{"insecure-registries": ["http://172.17.13.0:5000"],"builder": {"gc": {"enabled": true,"defaultKeepStorage": "20GB"}},"registry-mirrors": ["https://6kx4zyno.mirror.aliyuncs.com"],"features": {"buildkit": true},"experimental": false
}
