title: Docker process killed with cryptic `Killed` message
body: <p>Running a python script in a docker container and everything seems to be running smoothly, seeing some STDOUT messages, about 5 minutes in I get a <code>Killed</code> message with no further explanation and the process stops. Querying a db so could be a disk space issue, could be OOM issue. I'm not sure but I have no idea where to find logs about this kill message so I can get to the root of this problem. Any ideas where these logs are?</p>
  
  <p>Running docker-machine on Mac OSX.</p>
  
  <p>That's really all the message says!</p>
