docker build 的时候报错

docker build -t ratsql .
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by  ConnectTimeoutError(<pip._vendor.urllib3.connection.VerifiedHTTPSConnection object at 0x7fa39d852a90>,  Connection to pypi.org timed out. (connect timeout=15) ) : /simple/entmax/

缘由：

默认镜像下载速度很慢的缘由

解决办法：

在docker engine的配置文件里面增加下载路径

"http://hub-mirror.c.163.com",
"https://docker.mirrors.ustc.edu.cn",
"https://registry.docker-cn.com",
"https://cr.console.aliyun.com/"
