How To Verify the Cluster is Running a Supported Version of Kubernetes

Background

The RealTheory Collector is supported on certain versions of Kubernetes. If your Kubernetes environment is not running a supported version of Kubernetes, the RealTheory Collector cannot stream the cluster telemetrics data and the cluster will not show up in the RealTheory Console.

Solution

Verify that your Kubernetes environment is running a supported version of Kubernetes:

• 1.32
• 1.31
• 1.30
• 1.29
• 1.28
• 1.27
• 1.26
• 1.25

Procedure

1. Run the following command to verify the Kubernetes version running on your cluster:

   kubectl version
   

2. Verify that the output indicates a supported version of Kubernetes:
   Example:

   Client Version: v1.30.2  
   Server Version: v1.30.4
   

   Where the Server Version is the cluster's Kubernetes version and must be one of the supported versions.
