How to get server version?

To get the server version of Kubernetes, you can use the kubectl command-line tool. Here’s how to do it:

Open your terminal.
Run the following command:
```
kubectl version --output=json
```

This command will return the client and server version information in JSON format. Look for the serverVersion section in the output to find the server version details.

If you prefer a simpler output, you can use:

kubectl version

This will display both the client and server versions in a more human-readable format. The server version will be listed under the "Server Version" section.

Example output:

Client Version: v1.26.0
Server Version: v1.26.0

Make sure you have the necessary permissions and that your Kubernetes cluster is accessible.
