Compatibility

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

It is recommended to use versions of the components identical or close to the versions used by the operator’s end-to-end test suite (the specific version numbers are listed below).

Kubernetes

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

The Prometheus Operator uses the official Go client for Kubernetes to communicate with the Kubernetes API. The compatibility matrix for client-go and Kubernetes clusters can be found here. All additional compatibility is only best effort, or happens to be still/already supported.

The current version of the Prometheus operator uses the following Go client version:

v0.26.1
