title: Multiple .dockerignore files in same directory
body: <p>In the same directory I have two <code>Dockerfiles</code> and I would like to add a separate <code>.dockerignore</code> for each of them.</p>
  
  <p>Currently, I have:</p>
  
  <pre><code>Dockerfile.npm
  Dockerfile.nginx
  </code></pre>
  
  <p>But can I have something like this?:</p>
  
  <pre><code>.dockerignore.npm
  .dockerignore.nginx
  </code></pre>
