title: How can OpenAI Gym's visualizations work within Docker?
body: <p>I'd like to get OpenAI Gym working with the rendered OpenGL visualizations within a docker container.</p>
  
  <p>It's straightforward to get OpenAI Gym running within Docker. However, it's not immediately clear how to get the rendered environment to display in a window on my OS X laptop when you call <code>env.render()</code> on an OpenAI environment within the Docker container.</p>
  
  <p>How do I go about this?</p>
