> Containerizers assume caller will call 'destroy' if 'launch' fails.

> Key: MESOS-6214
> URL: https://issues.apache.org/jira/browse/MESOS-6214
> Project: Mesos
> Issue Type: Task
> Components: containerization
> Reporter: Benjamin Mahler
> Labels: tech-debt
>
> 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).
