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=quay.io/project-codeflare/instascale:<TAG> docker-build docker-push
• Note that the other contents of the Makefile (as well as the config and bin dirs) exist for future operator development, and are not currently utilized
• To deploy on kubernetes cluster use the deployments dir for now:

git clone https://github.com/project-codeflare/instascale.git
cd deployment/
oc apply -f instascale-sa.yaml
oc apply -f instascale-clusterrole.yaml
oc apply -f instascale-clusterrolebinding.yaml
oc apply -f deployment.yaml
