kube-scheduler

Deploying

• Create a WattTime account: https://www.watttime.org/api-documentation/#register-new-user
• Create PriorityClass
• Annotate nodes with:
  • bmc.siderolabs.com/endpoint
  • bmc.siderolabs.com/username
  • bmc.siderolabs.com/password
• Deploy the scheduler
• Create pod with priorityClassName referencing the PriorityClass created above
• Create pod with schedulerName set to kube-scheduler-siderolabs

Logic

• Evict pods with priority < index
• Power off nodes when idle AND no pods are in the queue (pending) with priority >= index
• Power on nodes when pods are in the queue (pending) with priority >= index
