Compatibility

The Prometheus Operator supports a number of Kubernetes and Prometheus releases.

Kubernetes#

The Prometheus Operator uses client-go to communicate with Kubernetes clusters. The supported Kubernetes cluster version is determined by client-go. The compatibility matrix for client-go and Kubernetes clusters can be found here. All additional compatibility is only best effort, or happens to still/already be supported. The currently used client-go version is “v4.0.0-beta.0”.

Due to the use of CustomResourceDefinitions Kubernetes >= v1.7.0 is required.

Due to the use of apiextensions.k8s.io/v1 CustomResourceDefinitions, prometheus-operator v0.39.0 onward requires Kubernetes >= v1.16.0.
