title: DOCKER_HOST environment variable on windows
body: <p>I'm running Docker 1.12.0 on a Windows 10 machine. I'm developing a Java program, using Maven 3.3.9 as a dependency manager. I have a maven docker plugin (<a href="https://github.com/fabric8io/docker-maven-plugin" rel="noreferrer">https://github.com/fabric8io/docker-maven-plugin</a>), which gives the following error on clean install.</p>
  
  <p>[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.15.16:build (docker-build-start) on project integration-test: Execution docker-build-start of goal io.fabric8:docker-maven-plugin:0.15.16:build failed: No <code>&lt;dockerHost&gt;</code> or <code>&lt;machine&gt;</code> given, no DOCKER_HOST environment variable, and no read/writable '/var/run/docker.sock' -> [Help 1]</p>
  
  <p>When I run a clean install with the following configuration option in the POM file:</p>
  
  <pre><code>&lt;dockerHost&gt;tcp://0.0.0.0:2376&lt;/dockerHost&gt;
  </code></pre>
  
  <p>the following result is shown.</p>
  
  <p>[ERROR] Failed to execute goal io.fabric8:docker-maven-plugin:0.15.16:build (docker-build-start) on project integration-test: Cannot create docker access object: Cannot extract API version from server <a href="https://0.0.0.0:2376" rel="noreferrer">https://0.0.0.0:2376</a>: Connect to 0.0.0.0:2376 [/0.0.0.0] failed: Connection refused: connect -> [Help 1]</p>
  
  <p>My question: is there an IP address I can use to tell this maven plugin where it can reach the daemon? Normal docker commands work perfectly fine. The plugin works without any problems on OS X.</p>
