删除中间容器38d22d97ec4a
2015/08/10 12:03:07命令[/ bin / sh -c apt-获取更新&& apt-get install -y netcat ca-certificates build-essential libssl-dev]返回一个非零代码：100
起初，我以为这是我的基本图像的一个问题，但是我没有在另一个VM上构建容器的问题。想法？
解决方案
这个问题围绕主机的网络配置。 eth0接口配置不正确。以下命令帮助我确定这是一个DNS问题。
$ docker run --rm debian：jessie ping -c 5 google .com
ping：未知主机
$ docker运行--rm debian：jessie ping -c 5 8.8.8.8

During my Docker container build process, I attemptted to install a few packages using apt-get install. However the process failed to complete because the 3 of the 4 packages could not be found.

Removing intermediate container 38d22d97ec4a
2015/08/10 12:03:07 The command [/bin/sh -c apt-get update && apt-get install -y netcat ca-certificates build-essential libssl-dev] returned a non-zero code: 100
At first, I thought this was an issue with my base image, however I have no issues building the container on another VM. Thoughts?
解决方案
This issue revolved around the host's network configuration. The eth0 interface was improperly configured. The following commands helped me determine it was a DNS issue.
$ docker run --rm debian:jessie ping -c 5 google.com
ping: unknown host
$ docker run --rm debian:jessie ping -c 5 8.8.8.8
