VolumePool

A VolumePool is a resource in Ironcore that represents a pool of storage volume managed collectively. It defines the infrastructure's storage configuration used to provision and manage volumes, ensuring resource availability and compatibility with associated VolumeClasses.

Example VolumePool Resource

An example of how to define a VolumePool resource in Ironcore

apiVersion: storage.ironcore.dev/v1alpha1
kind: VolumePool
metadata:
  name: volumepool-sample
spec:
  providerID: ironcore://shared
#status:
#  state: Available
#  availableVolumeClasses:
#    ironcore.dev/fast-class: 10Gi
#    ironcore.dev/slow-class: 100Gi

Key Fields:

• providerID(string): The providerId helps the controller identify and communicate with the correct storage system within the specific backened storage porvider.

  for example ironcore://shared

Reconciliation Process:

• Volume Type Discovery: It constantly checks what kinds of volumes (volumeClasses) are available in the Ironcore Infrastructure.

• Compatibility Check: Evaluating whether the volumePool can create and manage each volume type based on its capabilities.

• Status Update: Updating the VolumePool's status to indicate the volume types it supports, like a menu of available options.

• Event Handling: Watches for changes in VolumeClass resources and ensures the associated VolumePool is reconciled when relevant changes occur.
