CA: GCE: ignore empty ProviderID in NodeGroupForNode - #10189
Conversation
Upcoming MIG template nodes injected into ClusterSnapshot have an empty ProviderID. The ScaleUp quotas tracker walks those nodes and GCE currently returns an error, which aborts ScaleUp. AWS and Azure already return nil, nil.

What this PR does / why we need it:
Upcoming MIG template nodes injected into ClusterSnapshot have an empty ProviderID. ScaleUp quotas tracker calls
NodeGroupForNodeon every snapshot node, including those placeholders. GCE currently returns an error for an empty ProviderID, which aborts ScaleUp. AWS and Azure already return(nil, nil)for empty or unrecognized ProviderIDs. This change makes GCE do the same.GetMigForInstanceerrors are still returned.The path is ScaleUp -> newQuotasTracker -> calculateUsages -> NodeGroupForNode
