本文介绍了一种解决Docker在拉取镜像时遇到的超时问题的方法，通过更改Docker的镜像源地址，从https://registry.docker-cn.com更改为http://hub-mirror.c.163.com，成功解决了因连接超时导致的无法拉取镜像的问题，并展示了使用hello-world镜像验证Docker安装是否正确的过程。

运行docker run hello-world报错

Unable to find image 'hello-world:latest' locally
docker: 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).
See 'docker run --help'.

/etc/docker/daemon.json更换镜像https://registry.docker-cn.com为http://hub-mirror.c.163.com

{
"registry-mirrors":["http://hub-mirror.c.163.com"]
}

执行docker run hello-world打印日志如下，打印成功Hello from Docker!

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash
