为什么apt-get更新在Docker容器内失败？

在这个网站上也有类似的问题，但是我的问题与OSX Docker客户端（版本1.11.1-beta13.1（build：8193）e9f58bbe60f0debccc097b7d27cad200556ec6f5）有关。

当从debian:jessie容器运行apt-get update ，我得到以下输出：

 Err http://httpredir.debian.org jessie InRelease Err http://httpredir.debian.org jessie-updates InRelease Err http://security.debian.org jessie/updates InRelease Err http://httpredir.debian.org jessie Release.gpg Could not resolve 'httpredir.debian.org' Err http://security.debian.org jessie/updates Release.gpg Could not resolve 'security.debian.org' Err http://httpredir.debian.org jessie-updates Release.gpg Could not resolve 'httpredir.debian.org' Reading package lists...

They have been ignored, or old ones used instead. 

我怎样才能解决这个问题在OSX上？

当我们使用虚拟机时，我们依赖于它。 有些function可能无法正常工作。 因此，Docker团队努力消除Darwin系统（Mac OSX）中的这个挂起的虚拟机。

但要尝试解决您的问题，请尝试以下命令：

1. docker-machine restart default
2. docker-machine env default
3. eval "$(docker-machine env default)"
