Background

To enable CAPI MachineSets to still mirror MAPI MachineSets accurately, and to enable MAPI MachineSets to be implemented by CAPI MachineSets in the future, we need to implement a way to convert CAPI Machines back into MAPI Machines.

These steps assume that the CAPI Machine is authoritative, or, that there is no MAPI Machines.

Behaviours

• If no Machine exists in MAPI
  • But the CAPI Machine is owned, and that owner exists in MAPI
    • Create a MAPI Machine to mirror the CAPI Machine
    • MAPI Machines should set authority to CAPI on create
• If a MAPI Machine exists
  • Convert infrastructure template from InfraMachine to providerSpec
  • Update spec and status fields of MAPI Machine to reflect CAPI Machine
•  On failures
  • Set Synchronized condition to False and report error on MAPI resource
• On success
  • Set Synchronized condition to True on MAPI resource
  • Set status.synchronizedGeneration to match the auth resource generation

Steps

• Implement conversion based on the behaviours outlined above using the CAPI to MAPI conversion library

Stakeholders

• Cluster Infra

Definition of Done

• When a CAPI MachineSet scales up and is mirrored in MAPI, the CAPI Machine gets mirrored into MAPI
