泊坞窗构建没有网络，但码头工人跑了 [英] Docker build has no network, but docker run has

问题描述

如果我要建立我的Dockerfile，它无法连接到网络，或至少DNS：

If I want to build my Dockerfile, it can't connect to the network or at least DNS:

INFO[0001] The command "/bin/sh -c apt-get update -qq && apt-get install -y build-essential libpq-dev" returned a non-zero code: 100

但是，如果我通过泊坞窗运行它的工作原理运行完全相同的命令：

But if I run exactly the same command via docker run it works:

docker run --name="test" ruby /bin/sh -c 'apt-get update -qq && apt-get install -y build-essential libpq-dev'

有谁有一个想法，为什么泊坞窗构建不起作用？我已经尝试了所有DNS StackOverflow上相关的窍门，就像--dns 8.8.8.8等开始泊坞窗。

Does anybody have an idea, why docker build does not work? I have tried all DNS related tipps on StackOverflow, like starting docker with --dns 8.8.8.8 etc.

在此先感谢

推荐答案

试图运行我的码头工人，版本也未能 apt-get的升级完全相同的错误。我使用泊坞窗机在Mac OSX和一个简单的泊坞窗机重启默认解决了这个问题。不知道什么最初引起这一点，虽然。

My docker build also failed while trying to run apt-get upgrade with the exact same errors. I was using docker-machine on Mac OSX and a simple docker-machine restart default solved this issue. No idea what initially caused this, though.
