title: Copy directory to another directory using ADD command
body: <p>I have read <a href="http://docs.docker.com/engine/reference/builder/#add" rel="noreferrer">http://docs.docker.com/engine/reference/builder/#add</a> however I met a problem. I want to copy the local directory <code>go</code> to docker <code>/user/local/</code></p>
  <p>I tried:</p>
  <pre><code>ADD go /usr/local/
  </code></pre>
  <p>and:</p>
  <pre><code>ADD /go/ /usr/local/ 
  </code></pre>
  <p>also:</p>
  <pre><code>RUN chmod 0755 /usr/local/go/src/make.bash
  </code></pre>
  <p>However, I see the following error message:</p>
  <pre><code>/usr/local/go/src/make.bash: No such file or directory
  </code></pre>
  <p>but the local <code>go</code> directory does contain <code>make.bash</code>.</p>
