Docker cannot run hello-world from client
<p>I am trying to setup Docker for the first time. So, I'm following the guide here: <a href="https://docs.docker.com/machine/get-started/" rel="nofollow">https://docs.docker.com/machine/get-started/</a></p>

<p>Now, when I get to the following command:</p>

<pre><code>docker run busybox echo hello world
</code></pre>

<p>I get the following error:</p>

<pre><code>$ docker run hello-world
C:\Program Files\Docker Toolbox\docker.exe: An error occurred trying to connect: Post https://192.168.99.101:2376/v1.23/containers/create: Service Unavailable.
See 'C:\Program Files\Docker Toolbox\docker.exe run --help'.
</code></pre>

<p>Now, I am behind a corporate proxy so that may be the cause of my problem. I set it up according to what's mentioned in this article: <a href="http://mflo.io/2015/08/13/docker-machine-behind-proxy/" rel="nofollow">http://mflo.io/2015/08/13/docker-machine-behind-proxy/</a>. I did:</p>

<pre><code>docker-machine ssh default

  # now the command prompt will say something like:
  # docker@default:~$

  # we need root access:
  sudo -s

  # now the command prompt will say something like:
  # root@default:~$

  # now configure the proxy
  echo "export HTTP_PROXY=http://[uid]:[pw]@corporate.proxy.com:[port]" &gt;&gt; /var/lib/boot2docker/profile
  echo "export HTTPS_PROXY=http://[uid]:[pw]@corporate.proxy.com:[port]" &gt;&gt; /var/lib/boot2docker/profile

  # for verification
  cat /var/lib/boot2docker/profile

  # exit out of ssh session
  exit
  exit

  # restart
  docker-machine restart default

  # now you should be able to proceed with installation steps
  docker run hello-world
</code></pre>

<p>On the Docker-Machine, I got absolutely no problem with the <code>"docker run hello-world"</code> as well as <code>"docker run busybox echo hello world"</code></p>

<p>However, on my computer, this same command always return the same error...</p>
