# 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:

- 1.35
- 1.34
- 1.33
- 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: v1.33.5
Server Version: v1.33.5
```

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