title: How to know the reason why a docker container exits?
body: <p>I have a Docker container running in a host of 1G RAM (there are also other containers running in the same host). The application in this Docker container will decode some images, which may consume memory a lot. </p>
  
  <p>From time to time, this container will exit. I doubt it is due to out of memory but not very sure. I need a method to find the root cause. So is there any way to know what happened for this container's death? </p>
