title: Running a language server in a Dockerfile: Binary file of the Language Server
body: <p>I built a simple language server following this tutorial:</p>
  
  <p><a href="http://www.eclipse.org/Xtext/documentation/102_domainmodelwalkthrough.html" rel="nofollow noreferrer">http://www.eclipse.org/Xtext/documentation/102_domainmodelwalkthrough.html</a></p>
  
  <p>In this server, I have 5 folders, </p>
  
  <pre><code>org.example.domainmodel
  org.example.domainmodel.ide
  org.example.domainmodel.tests
  org.example.domainmodel.ui
  org.example.domainmodel.ui.tests
  </code></pre>
  
  <p>Now I need to run this language server inside a Docker image, and need the binary directory for it. Which binary directory out of the above 5 folders should I use? The actual language servers I've explored so far are quite different from what I've created.</p>
