heyselbi / instascale

On-demand Kubernetes/OpenShift cluster scaling and aggregated resource provisioning

Instascale controller

High Level Steps

• User submits Multi GPU job(s)
• Job(s) lands in MCAD queue
• When resources are not available it triggers scaling i.e. calls instascale
• Instascale looks at resource requests specified by the user and matches those with the desired Machineset(s) to get nodes.
• After instascaling, when aggregate resources are available to run the job MCAD dispatches the job.
• When job completes, resources obtained for the job are released.

Usage

• To build locally : make run
• To build and release a docker image for controller : make IMG=asm582/instascale docker-build docker-push
• To deploy on kubernetes cluster use deployments for now

Testing

TBD
