Windows下的docker中pull的时候出现下面的错误：
PS C:\Users\xxx> docker pull hello-world Using default tag: latest 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)
镜像配置原因，我的是因为配置了阿里云导致报错，去除阿里云的，保留其他的之后pull成功
"registry-mirrors": ["https://mirror.ccs.tencentyun.com","http://hub-mirror.c.163.com","https://registry.docker-cn.com"]
