[Draft] BIOS/Firmware Update

[afritzler]

Summary

Issue to discuss approaches on how we envision to perform BIOS and firmware update.

Discussed approaches

Bulk update via central image

Perform a bulk update for all applicable components via a given image containing all the logic necessary to update the various components.

apiVersion: metal.ironcore.dev/v1alpha1
kind: Server
metadata:
  name: foo-server
spec:
  firmware:
       manufacturer: ACME Corp.
       version: 2.0.0
status:
  firmware:
     manufacturer: ACME Corp.
     version: 1.0.0

Individual components

Expose the version information directly in the Server spec and let the ServerReconciler do the corresponding update operations.

apiVersion: metal.ironcore.dev/v1alpha1
kind: Server
metadata:
  name: foo-server
spec:
  firmwares:
  - name: BIOS
    manufacturer: ACME Corp.
    version: 1.0.0
  - name: SSD
    manufacturer: ACME Corp.
    version: 2.0.0
  - name: NetworkInterfaceCard
    manufacturer: ACME Corp.
    version: 1.0.0
status:
  firmwares:
  - name: BIOS
    manufacturer: ACME Corp.
    version: 1.0.0
  - name: SSD
    manufacturer: ACME Corp.
    version: 2.0.0
  - name: NetworkInterfaceCard
    manufacturer: ACME Corp.
    version: 1.0.0

Use a dedicated type to describe the updates

Define an own type describing the desired updates for a particular Server by referencing it via .spec.serverRef.

apiVersion: metal.ironcore.dev/v1alpha1
kind: ServerFirmware
metadata:
  name: foo-server
spec:
  serverRef:
    name: foo
  firmwares:
  - name: BIOS
    manufacturer: ACME Corp.
    version: 1.0.0
  - name: SSD
    manufacturer: ACME Corp.
    version: 2.0.0
  - name: NetworkInterfaceCard
    manufacturer: ACME Corp.
    version: 1.0.0
status:
  firmwares:
  - name: BIOS
    manufacturer: ACME Corp.
    version: 1.0.0
  - name: SSD
    manufacturer: ACME Corp.
    version: 2.0.0
  - name: NetworkInterfaceCard
    manufacturer: ACME Corp.
    version: 1.0.0
