Overview
FireboltEngineClass is an optional namespaced resource that holds reusable FireboltEngine settings: a pod-template fragment plus defaults for storage, customEngineConfig, rollout, drainCheckEnabled, drainCheckInterval, and autoStop. Engines in the same namespace reference it through spec.engineClassRef so scheduling, identity, sidecars, engine image, storage, engine config, and rollout and auto-stop policy stay consistent without duplicating YAML on every engine.
Each inherited field resolves the engine value first, then the class value, then the Firebolt Operator’s default. An engine that sets a field owns it. The class fills it in otherwise.
Multiple classes can exist per namespace. The Engine picks one by name, and using a class is optional. See EngineClass configuration inheritance for template precedence, per-Engine overrides, deletion, and rollout behavior.
For the allowlist of user-settable and Firebolt Operator-owned template fields, see the FireboltEngineClass CRD reference.
