You can use static reservation to make your marathon framework running on a specified node, the steps are as following, 0.24 do not support implicit role, so you need to restart master to add role flags.
1) Restart mesos master with role flags, such as --roles=marathon 2) Start up agent on master node with static reservation, such as --resources="cpus(marathon):16;mem(marathon):24576 3) Start marathon with a role flag: --mesos_roles=marathon, refer to https://github.com/mesosphere/marathon/blob/master/docs/docs/command-line-flags.md for detail. Then you can see that your marathon framework will be starting on the node with static reservation, hope this helps.
