Subject [jira] [Created] (MESOS-3325) Running mesos-slave@0.23 in a container causes slave to be lost after a restart

Chris Fortier created MESOS-3325:
------------------------------------

             Summary: Running mesos-slave@0.23 in a container causes slave to be lost after
a restart
                 Key: MESOS-3325
                 URL: https://issues.apache.org/jira/browse/MESOS-3325
             Project: Mesos
          Issue Type: Bug
          Components: slave
    Affects Versions: 0.23.0
         Environment: CoreOS, Container, Docker
            Reporter: Chris Fortier
            Priority: Critical


We are attempting to run mesos-slave 0.23 in a container. However it appears that the mesos-slave
agent registers as a new slave instead of re-registering. This causes the formerly-launched
tasks to continue running.

systemd unit being used:

ps, yes I saw the coreos-setup repo was deprecated.
