             Summary: Containerizers assume caller will call 'destroy' if 
'launch' fails.
                 Key: MESOS-6214
             Project: Mesos
          Issue Type: Task
          Components: containerization
            Reporter: Benjamin Mahler

The planned API for nested containers is to allow launching, waiting (for 
termination), and killing (currently only SIGKILL) of the nested container. 
Note that this API provides no mechanism for "cleaning up" the container 
because it will implicitly do so once the container terminates.

However, the containerizer currently assumes that the caller will call destroy 
if the launch fails. In order to implement the agent's API for managing nested 
containers, we will have to set up a failure continuation to call destroy to 
ensure the cleanup occurs correctly.

Ideally, the API of the containerizer does not require the caller to call 
destroy after a launch failure, given that the launch did not succeed it seems 
counter-intuitive for the responsibility of clean up to be on the caller. In 
addition, in the container termination case, the containerizer will implicitly 
clean up (so this seems inconsistent as well).
