Alexander Rukletsov created MESOS-4935:
------------------------------------------
Summary: Docker executor does not track containers killed
out-of-band.
Key: MESOS-4935
URL: https://issues.apache.org/jira/browse/MESOS-4935
Project: Mesos
Issue Type: Improvement
Components: docker
Reporter: Alexander Rukletsov
If a docker container is killed out-of-band (using docker CLI), the docker
executor does not exit and hence does not report a terminal state to Mesos. It
happens because the docker executor does not monitor the state of the
underlying container and waits for an explicit {{killTask()}} or
{{shutdown()}}:
https://github.com/apache/mesos/blob/69b2ad528dd79979a8ee113a8edbbab2669e32e6/src/docker/executor.cpp#L278
We should consider introducing a container observer actor, similar to
{{ReaperProcess}} we have for command executor-based tasks.
