Run these commands against the Syself Autopilot management cluster, not the workload cluster, to find which Kubernetes version and Cluster Stack release your cluster uses.

## Check one cluster

```console
$ kubectl get cluster <cluster-name> -n <namespace> \
  -o jsonpath='{.spec.topology.classRef.name}{"\n"}'
```

The command returns the Cluster Stack release name:

```console vars
hetzner-apalla-1-33-v13
```

The name includes the provider, stack, Kubernetes minor version, and Cluster Stack release. The final `vN` segment identifies the Cluster Stack release.

## Check every cluster

```console
$ kubectl get clusters -A \
  -o custom-columns='NAMESPACE:.metadata.namespace,CLUSTER:.metadata.name,CLUSTERSTACK:.spec.topology.classRef.name,KUBERNETES:.spec.topology.version'
```

## If the management cluster serves `cluster.x-k8s.io/v1beta1`

If the Syself Autopilot management cluster serves `cluster.x-k8s.io/v1beta1` instead of `v1beta2`, use `spec.topology.class` instead of `spec.topology.classRef.name`.

To check one cluster:

```console
$ kubectl get cluster <cluster-name> -n <namespace> \
  -o jsonpath='{.spec.topology.class}{"\n"}'
```

To check every cluster:

```console
$ kubectl get clusters -A \
  -o custom-columns='NAMESPACE:.metadata.namespace,CLUSTER:.metadata.name,CLUSTERSTACK:.spec.topology.class,KUBERNETES:.spec.topology.version'
```

Use the version picker below to select the Kubernetes minor and Cluster Stack release that match the values for your cluster.

Documentation is tailored to each Cluster Stack release. Select the Kubernetes minor and release your cluster currently uses, rather than the latest version, to see the documentation that applies to your cluster.
