Job priorities, eviction and pre-emption #309

Open aluzzardi opened 8 years ago

aluzzardi commented 8 years ago

Right now, every Job has the same priority and if no candidate node is available the Task stays in PENDING state.

An alternative would be to provide a priority to every Job.

When no node is available to schedule a task, the scheduler would try to evict one or more lower priority task to make room for it.

Since eviction might be costly, Jobs could hint they are Preemptive - therefore informing the scheduler that it's okay to evict them to make room for someone else.

Tentatively moving to 1.13. This may not be what we end up doing but it's still relevant

Is this issue still active? What's the plan?

machisuji commented 3 years ago

I need this badly. I don't think it's possible right now with swarmkit which will likely force me to use kubernetes (which does support preemption) instead.
