Generic Engine Fallback
Use this only when all three statements are true:
- kubeblocks-preflight has already produced a recommendation bundle.
references/coverage/engine-tier-map.yamldoes not place the target engine in the Tier-1 dedicated set.references/routing/route-matrix.yamlallows the request to continue throughkubeblocks-engine-generic.
What This Entry Must Decide
Before applying any generic Cluster manifest, make the following explicit:
clusterDefandtopologyserviceVersionstorageClassNameand any topology-aware storage requirement from preflight- sizing profile
- connection / verification plan
- next-hop operations and observability path
Generic Workflow
- Confirm the engine really belongs to the generic fallback.
- Gather
clusterDef,topology, and component names from the live environment. - Fill the preserved generic Cluster template in legacy reference.md.
- Validate with
kubectl apply --dry-run=server. - Apply and verify the cluster reaches
Running.
Never use this as the default path for any Tier-1 engine.
