title: How to increase docker-machine memory Mac
body: <p>I am new to Docker, and trying to go through this tutorial setting up MemSQL from a Docker image - <a href="http://docs.memsql.com/4.0/setup/docker/">http://docs.memsql.com/4.0/setup/docker/</a> .  I am on a Mac, and the tutorial uses <code>boot2docker</code> which seems to have been deprecated.  </p>
  
  <p>The VM needs 4GB memory to run.  The tutorial specifies how to do this with <code>boot2docker</code> but I cannot find a way to do this with the docker-machine/docker toolbox. </p>
  
  <p>Here is the command I am using and the error I am getting just trying to go through the tutorial without altering the boot2docker config.  </p>
  
  <pre><code>docker run --rm --net=host memsql/quickstart check-system
  Error: MemSQL requires at least 4 GB of memory to run.
  </code></pre>
