Hello i am currently trying to activate checkpointing for my Mesos cloud.
Starting from an application running in a docker container on the cluster, launched from marathon, my use cases are the followings: *UC1: kill the marathon service, then restart after 2 minutes.* *Expected*: the mesos task is still active, the docker container is running. When the marathon service restarts, it get backs its tasks. *Result*: OK *UC2: kill the mesos slave, then restart after 2 minutes.* *Expected*: the mesos task remains active, the docker container is running. When the mesos slave service restarts, it get backs its tasks. Marathon does not show error. *Results*: task get status LOST when slave is killed. Docker container still running. Marathon detects the application went down and spawn a new one on another available mesos slave. When the slave restarts, it kills the previous running container and start a new one. So i end up with 2 applications on my cluster, one spawn by Marathon, and another orphan one. Is this behavior normal? Can you please explain what i am doing wrong? ----------------------------------------------------------------------------------------------------------- Here is the configuration i have come so far: Mesos 0.19.1 (not dockerized) Marathon 0.6.1 (not dockerized) Docker 1.3 + Deimos 0.4.2 Mesos master is started: */usr/local/sbin/mesos-master --zk=zk://...:2181/mesos --port=5050 --log_dir=/var/log/mesos --cluster=CLUSTER_POC --hostname=... --ip=... --quorum=1 --work_dir=/var/lib/mesos* Mesos slave is started: */usr/local/sbin/mesos-slave --master=zk://...:2181/mesos --log_dir=/var/log/mesos --checkpoint=true --containerizer_path=/usr/local/bin/deimos --executor_registration_timeout=5mins --hostname=... --ip=... --isolation=external --recover=reconnect --recovery_timeout=120mins --strict=true* Marathon is started: *java -Xmx512m -Djava.library.path=/usr/local/lib -Djava.util.logging.SimpleFormatter.format=%2$s %5$s%6$s%n -cp /usr/local/bin/marathon mesosphere.marathon.Main --zk zk://...:2181/marathon --master zk://...:2181/mesos --local_port_min 30000 --hostname ... --event_subscriber http_callback --http_port 8080 --task_launch_timeout 300000 --local_port_max 40000 --ha --checkpoint*
