Source-backed version compatibility
Prometheus Operator Kubernetes version compatibility. Prometheus Operator 0.84.0 and newer require Kubernetes 1.25.0 or newer because the CRDs use CEL validation.
Quick answer
Supported and tested versions have compatibility evidence. Recommended and bundled versions describe upstream choices without establishing compatibility. Versions outside the documented coverage are unknown, not necessarily incompatible.
Supported Kubernetes versions
Prometheus Operator 0.84.0 and newer require Kubernetes 1.25.0 or newer because the CRDs use CEL validation.
Kubernetes 1.23.0 or newer is also documented when the CustomResourceValidationExpressions feature gate is enabled; this range records the default configuration.
