description: >-
  Rook is Apache 2.0 open-source software hosted by the CNCF; it does not issue invoices.
  The relevant FinOps surface is the underlying compute, storage, and network capacity the
  operator consumes on the host Kubernetes cluster, plus any optional commercial-support
  contract with a vendor such as Clyso or Red Hat (OpenShift Data Foundation).

    description: >-
      Provisioned Ceph storage capacity managed by Rook (block, file, object); cost is
      incurred on the host cloud / on-prem hardware, not by Rook.
    unit: GB-month

    dimensions:
      - storage_class

  - name: compute_resources
    description: >-
      CPU and memory consumed by Rook operator pods, OSDs, MONs, MGRs, and RGWs on the host
      Kubernetes cluster.

      - component

      Annual subscription with a third-party support vendor (Clyso, Red Hat ODF). Optional.

    description: >-
      Track Rook-managed storage usage with Ceph dashboards, Prometheus exports from the
      Rook operator, and the host cloud/cluster cost surface; there is no Rook-issued usage
      API.
  - name: Allocation
    description: >-
      Tag Rook namespaces, storage classes, and CephBlockPools to the consuming workload so
      that capacity and IO can be attributed back to the team that owns the data.
  - name: Optimization
    description: >-
      Right-size OSD count, choose appropriate replication vs erasure-coding, set per-pool
      quotas, and tier rarely accessed data to lower-cost storage classes; consolidate small
      Ceph clusters to amortize MON/MGR overhead.
  - name: Accountability
    description: >-
      Platform engineering owns the Rook/Ceph cluster; consuming teams own per-namespace and
      per-pool quotas. Treat any vendor-support contract as a normal SaaS line item under
      platform budget.
