Docker构建没有网络，但是docker运行有 [英] Docker build has no network, but docker run has

问题描述

如果我要构建我的Docker文件，它不能连接到网络或至少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 docker run 运行完全相同的命令，它的工作原理是：

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'

有人有想法，为什么 docker build 不工作？我已经尝试了StackOverflow上的所有DNS相关提示，例如使用--dns 8.8.8.8等启动docker。

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.

提前感谢

推荐答案

我也有类似的问题。但是当我运行AWS linux时，我没有systemctl。我解决了：

I had similar problem. But as I was running AWS linux i had no systemctl. I solved using:

sudo service docker restart
