title: pull access denied repository does not exist or may require docker login
body: <p>I am using Laravel 4.2 with docker. I setup it on local. It worked without any problem but when I am trying to setup online using same procedure then I am getting error:</p>
  <pre><code>pull access denied for &lt;projectname&gt;/php, repository does not exist or may require 'docker login'
  </code></pre>
  <p>is it something relevant to create repository here <a href="https://cloud.docker.com/" rel="noreferrer">https://cloud.docker.com/</a>  or need to docker login in command?</p>
  <p>After days of study I am still not able to figure out what could be the fix in this case and what are the right steps?</p>
  <p>I have the complete code. I can paste here if need to check certain parts.</p>
