Applying an application manifest that includes kind BackupSchedule fails because the API is unknown. What does this most likely indicate?
Select an answer to reveal the explanation.
Short Explanation
If Kubernetes says the kind is unknown, the recipe card was never filed—the CRD (and usually its Operator) is missing. Install the extension first. Manifests cannot invent APIs out of thin air.
Full Explanation
The API server only admits types it knows—built-in resources or installed CRDs. A failure that the kind/BackupSchedule API is unknown typically means the defining CRD (often delivered with an Operator) is absent. Pod Security does not convert kinds to ConfigMaps, replica counts do not register APIs, and namespaces do not stash unknown kinds as annotations for later.
