但hello-worlddocker 示例运行良好：

root@k8s-eu-1-master:~# docker run hello-world

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

这是输出docker info：

如何让它工作？

Answer 1

我在进行 docker build 时遇到了同样的问题，使用@Raphael10 发布的下面的命令解决了这个问题。

添加有效的 DNS 服务器/etc/resolv.conf

 nameserver 8.8.8.8
 nameserver 8.8.4.4

Answer 2

通过在 /etc/resolv.conf 中添加这两行来解决

    nameserver 8.8.8.8
    nameserver 8.8.4.4

进而：

    root@k8s-eu-1-master:~# sudo systemctl daemon-reload
    root@k8s-eu-1-master:~# sudo systemctl restart docker
