Multi-agent machine
Is it possible to setup a machine such that multiple mesos agents are
running on the same machine and registering with the same master?
For example, with different cgroup roots or different default working
directory.

Ok, thanks!

Maintenance should work in this case, it will just be applied to all agents
on the machine.

Thanks for the insight.
I take that to mean the maintenance primitives might not work right for
multi-agent machines? aka, I can't do maintenance on one agent but not the
others?

Charles,
It should be possible. Here are the global 'object' that might conflict:
1) cgroup (you can use different cgroup root)
2) work_dir and runime_dir (you can set them to be different between agents)
3) network (e.g., iptables, if you use host network, should not be a
problem. Otherwise, you might need to configure your network isolator
properly)
But we haven't tested. Another potential thing that might come up is the
code that rely on hostname of the agent (MachineID in maintenance
primitive?)

Use case:
setting cgroup root per agent so that I can better control kernel level
tunings

The use case? Development setup on a single VitrualBox VM to simulate a cluster? To safe laptop resources? Or something more behind?

Is it possible to setup a machine such that multiple mesos agents are running on the same machine and registering with the same master?
For example, with different cgroup roots or different default working directory.
