Static reservation feature will help; but there's a limitation that Marathon can only manage resources from one role. For example, if we use static reservation for two resources group "master" (--resources="cpus(master):16") & "agent" (--resources="cpus(agent):16"), Marathon (--mesos_roles="master" or --mesos_roles="agent") can only get resources from one of them: "master" or "agent".
There's EPIC to support multiple roles in Mesos (MESOS-1763). ---- Da (Klaus), Ma (马达) | PMP® | Advisory Software Engineer Platform OpenSource Technology, STG, IBM GCG +86-10-8245 4084 | [email protected] | http://k82.me On Wed, Feb 24, 2016 at 10:21 PM, Guangya Liu <[email protected]> wrote: > 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. > > Thanks, > > Gaungya > > On Wed, Feb 24, 2016 at 9:41 PM, Clarke, Trevor <[email protected]> wrote: > >> I've got a custom framework running in mesos (0.24.1 for now).
