Ubuntu18.04LTS日志8-拉docker镜像遇到的小问题

（1）Error response from daemon: Get https://registry-1.docker.io/v2/: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

解决方法：

这个时候是因为镜像从国外拉取，此处修改拉取地址
sudo vim /etc/docker/daemon.json

添加：阿里云镜像
{
“registry-mirrors”:[“https://6kx4zyno.mirror.aliyuncs.com”]
}

中科院镜像
{
“registry-mirrors”:[“https://docker.mirrors.ustc.edu.cn”]
}

（2）Error response from daemon: Get https://registry-1.docker.io/v2/spellrun/pytorch/manifests/latest: Get https://auth.docker.io/token?scope=repository%3Aspellrun%2Fpytorch%3Apull&service=registry.docker.io: net/http: request canceled while waiting for connection (Client.Timeout exceeded while awaiting headers)

解决方法：
step1：先输入 dig @114.114.114.114 registry-1.docker.io
step2：这里看到registry-1.docker.io. 53 IN A 52.87.94.70

step3：新建一个窗口，sudo vim /etc/hosts

step4：添加地址

step5：保存退出，重启docker就可以愉快的下载了。
