title: Start kubernetes container with specific command
body: <p>Using fleet I can specify a command to be run inside the container when it is started. It seems like this should be easily possible with Kubernetes as well, but I can't seem to find anything that says how. It seems like you have to create the container specifically to launch with a certain command.</p>
  
  <p>Having a general purpose container and launching it with different arguments is far simpler than creating many different containers for specific cases, or setting and getting environment variables.</p>
  
  <p>Is it possible to specify the command a kubernetes pod runs within the Docker image at startup? </p>
