Expose status.capacity.storage kubernetes_persistent_volume_claim(_v1)

[mindw]

Description

Some CSI implementations provision volume sizes which are different from the requested storage. For example OKE (Oracle Kubernetes Engine) rounds up the requested storage to 50Gi (as documented in https://docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengcreatingpersistentvolumeclaim_topic-Provisioning_PVCs_on_BV.htm)
It would be useful to detect this condition for various purposes cost calculations, volume resizing decisions and so on).

Potential Terraform Configuration

data "kubernetes_persistent_volume_claim_v1" "self" {
  metadata {
    namespace = "monitoring"
    name      = "victoria-materics-single-server-0"    
  }
}

output "vm_volume_size" {
  value = data.kubernetes_persistent_volume_claim_v1.self.status_capacity_storage
}
