title: How to see docker build "RUN command" stdout? (docker for windows)
body: <p>In the past I could simply do something like this:</p>
  <p><code>Dockerfile</code>:</p>
  <pre><code>FROM ubuntu
  RUN echo &quot;test&quot;
  </code></pre>
  <p>which would output <code>test</code> to my shell. I used this as a way of debugging my builds.</p>
  <p>In the latest stable version of docker for windows the build output looks completely different and is not showing any stdout from any command.</p>
  <p>How can I see the output of any command in the build process?</p>
  <p>The current output looks like this for above <code>Dockerfile</code> example:</p>
