Tobias Mueller commented on MESOS-5102: --------------------------------------- I had a look at https://issues.apache.org/jira/browse/MESOS-4355 and I'm not sure whether it'll be implemented so that a already created Docker volume can be used, or that it will be possible to actually create a Docker volume from the Mesos isolator itself. Ideally, I think it'd be great if a Marathon app could create a volume upon launch, and reuse a volume if the task is migrated of restarted. What is not really clear to me is if there isn't a need for some kind of volume-to-application (instance) registration, because otherwise I can't imagine how it would be possible to match a pre-existing volume to an application. Also, I'm not sure how scaling of apps and their instance volumes can be handled. The mesos/elasticsearch framework (http://mesos-elasticsearch.readthedocs.org/en/latest/) already supports an '--externalVolumeDriver' flag, but I'm not 100% sure how this was implemented. > Support persistent volumes via Docker volume drivers > ---------------------------------------------------- > > Key: MESOS-5102 > URL: https://issues.apache.org/jira/browse/MESOS-5102 > Project: Mesos > Issue Type: Improvement > Components: containerization, docker > Affects Versions: 0.28.0 > Reporter: Tobias Mueller > > To my understanding it's currently not possible to create persistent volumes > via Docker volume drivers/plugins.
