Docker - apt-get 连接在 Debian 上被拒绝，但在 Ubuntu 上工作

Question

我是 docker 新手，所以请耐心等待 --

我正在尝试在 docker 映像上安装软件包。我无法在基于 Debian 的图像上找到任何地方。

C:\me\docker-images> docker run --rm -it debian:stretch
root@74414ba0234b:/# apt-get update

W: Some index files failed to download. They have been ignored, or old ones used instead.

我什至无法 ping 任何东西：

root@71136f0cb68d:/# ping google.ca
PING google.ca (172.217.12.227) 56(84) bytes of data.

它在这里冻结。

但它适用于 ubuntu：

当然他们访问不同的 URL，但我怀疑 debian 服务器在线，因为我可以通过网络访问它。

为什么我的连接受限于 Debian 而不是 Ubuntu 映像？

Answer 1

我提取了相同的图像并尝试了，ping 和 apt-get update 工作正常。

请重启 docker 服务并重试。

sudo service docker restart

Answer 2

如果您使用的是 Docker Machine，您可能想尝试运行：

docker-machine restart
