MachinePool

A MachinePool is a resource in Ironcore that represents a pool of compute resources managed collectively. It defines the infrastructure's compute configuration used to provision and manage Machines, ensuring resource availability and compatibility with associated MachineClasses. (Note: One machinepoollet is responsible for one MachinePool)

Example MachinePool Resource

An example of how to define a MachinePool resource:

apiVersion: compute.ironcore.dev/v1alpha1
kind: MachinePool
metadata:
  name: machinepool-sample
  labels:
    ironcore.dev/az: az1
spec:
  providerID: ironcore://shared

Key Fields:

• ProviderID(string): The providerId helps the controller identify and communicate with the correct compute system within the specific backend compute provider. For example ironcore://shared

Reconciliation Process

• Machine Type Discovery: It constantly checks what kinds of MachineClasses are available in the Ironcore Infrastructure
• Compatibility Check: Evaluating whether the MachinePool can manage available machine classes based on its capabilities.
• Status Update: Updating the MachinePool's status to indicate the supported MachineClasses with available capacity and allocatable.
• Event Handling: Watches for changes in MachineClass resources and ensures the associated MachinePool is reconciled when relevant changes occur.
