After all this, a full reboot solved the problem - although, that still doesn't answer what it was.

If anyone knows what the actual cause was, I'm still curious, but for now the problem is gone.

You could install tools like <code>dig</code> inside the docker image to alanyse the issue.

use static hosts in your <code>/etc/hosts</code> file te make apt-get run inside the docker image. add these lines to your hosts file:

<pre><code>213.32.5.7 debian.mirrors.ovh.net
141.76.2.4 ftp.de.debian.org 
217.196.149.233 mirror-conova-security.debian.org
212.211.132.250 lobos.debian.org
212.211.132.250 security.debian.org 
5.153.231.4 http.debian.net 
151.101.12.204 cdn-fastly.deb.debian.org
151.101.12.204 security-cdn.debian.org
</code></pre>

I'm having an interesting problem running docker containers: out of the blue, I'm not able to resolve DNS from within the container.

Here's a rundown: 

<ol>
<li>Nothing is resolving; apt-get, pip, one-off ping containers, etc. Running <code>docker run -it --dns=8.8.8.8 ubuntu ping www.google.com</code> results in <code>ping: unknown host www.google.com</code> both with and without the <code>--dns</code> flag.</li>
<li>I can reach 8.8.8.8 both from inside and outside the containers. <code>docker run -it ubuntu ping 8.8.8.8</code> works.</li>
<li>I've configured the containers to use both 8.8.8.8, 8.8.8.4, and my local network DNS servers (in various permutations) both by editing <code>/etc/sysconfig/docker</code> to add <code>DOCKER_OPTS="--dns 8.8.8.8 --dns 8.8.8.4"</code> and by setting the <code>--dns 8.8.8.8</code> flag on the containers at runtime. <code>systemctl restart docker</code> was run between each change. </li>
<li><code>ip_forward</code> is enabled. (see <a href="https://github.com/docker/docker/issues/490">here</a>)</li>
<li>I've done a full reset as specified <a href="https://github.com/docker/docker/issues/866#issuecomment-19218300">here</a>.</li>
</ol>

I'm running Fedora 21, docker client version 1.5.0.

Any ideas? I'm at a complete loss as to what's preventing docker from accessing the Internet successfully.

Docker container can reach DNS but not resolve hosts

我在运行docker容器时遇到了一个有趣的问题:突然之间，我无法从容器中解决DNS问题。下面是一篇文章：没有什么是解析的；apt-get、pip、一次性ping容器等等。运行docker run -it --dns=8.8.8.8 ubuntu ping www.google.com会导致ping: unknown h...
