希望大佬可以加上daocloud的加速站，这个是我测试的最快的一个
http://f1361db2.m.daocloud.io

This tool is very exciting, and I love it very much. But the speed of pulling the Cent OS image is too slow, I think if we could use other faster methods to test the mirror servers's speed, we can make this fancy tool easier to use.

一个月前我访问 https://registry.docker-cn.com，就是下面的情况连接超时：

C:\Users\XhstormR>curl -ik https://registry.docker-cn.com
curl: (7) Failed to connect to registry.docker-cn.com port 443: Timed out

今天我访问 https://www.docker-cn.com/get-docker，发现跳到 www.docker.com 了，貌似 Docker 不打算提供**服务了。

默认ubuntu20.04下apt安装docker，并无配置文件，相关的配置的是在/lib/systemd/system/docker.service中直接配的，它默认并不引用配置文件。

• docker.errors.APIError: 400 Client Error: Bad Request ("client is newer than server (client API version: 1.35, server API version: 1.21)")

比如：

>>> import docker
>>> client = docker.from_env()
>>> version = client.version()[u'Version']
>>> version
'19.03.7'
>>>

version中没有ce子串，没有应用修改 /etc/docker/daemon.json 的换镜像方式

    if "ce" in version:
        set_docker_config_ce(best_mirror_url)
    else:
        set_docker_config(best_mirror_url)

此处的识别有点毛病

should i create this file mannually ?
