- Adding Support for ephemeral storage.
- Support for events feature in Firmament.
- Static Persistant Volume support, more info.
- Bug fixes and minor performance improvements.
To enable the new CPU-MEM cost model --flow_scheduling_cost_model
flag should be set to '10'
like shown below
--flow_scheduling_cost_model=10
To enable the Pod Affinity/Anti-Affinity symmetry --pod_affinity_antiaffinity_symmetry
flag should be set to 'true' in the firmament config file
like show below
firmament_scheduler_cpu_mem.cfg=true
This fix is based above the CPU-MEM cost model. This feature currently are not supported in other cost model.
Ephemeral Storage and Events support. Static Persistant Volume support is also avaliable from the V0.5 'Poseidon' release.
This works with V0.5 Poseidon release. There is no change for this feature in firmament.
Pre-Bound PVC to a PV will be picked by 'Poseidon' if a Pod has that PVC requirement.
It will be used as a node selector term in the NodeAffinity 'Hard-constraint' section of the Pod.
When 'Frimament' try to schedule this Task it will try to satify the NodeAffinity Hard Constraints, which will result in the Pod getting scheduled on the Node which satisfy the PV's NodeSelector term.
