# Update a Cluster
Update a Managed Kubernetes cluster on IONOS CLOUD: modify cluster name, version, maintenance window, and access settings using the DCD.
You can update Public and Private node pool clusters from the [DCD](https://docs.ionos.com/cloud/support/general-information/glossary-of-terms#data-center-designer-dcd).
## Edit cluster settings
To update a cluster, follow these steps:
{% stepper %}
{% step %}
### Navigate to the cluster settings
1. In the **DCD**, go to **Menu** > **Containers** > **Managed Kubernetes**.
2. Select a cluster from the list. You can click on the name of the cluster or select **Open** from the **OPTIONS** column.
3. Navigate to the **Cluster settings** tab.
{% endstep %}
{% step %}
### Update cluster properties
1. *(Optional)* Update the **Cluster name**, or continue with the existing cluster name.
{% hint style="info" %}
**Note:** Make sure to use the following naming convention for the Kubernetes cluster:
* Can be a maximum of 63 characters in length.
* Begins and ends with an alphanumeric character (\[a-z0-9A-Z]).
* Must not contain spaces or any other white-space characters.
* Can contain dashes (-), underscores (\_), and dots (.) in between.
{% endhint %}
2. Select a **Kubernetes version** number from the drop-down list to use another version.
{% endstep %}
{% step %}
### Location and network access
You cannot modify these details after a cluster is configured.
{% endstep %}
{% step %}
### Additional settings
1. Toggle **Audit logging** to enable or disable audit logging for the cluster. When enabled, a **Target Object Storage bucket** field appears; enter the name of an existing Object Storage bucket where audit logs will be stored.
2. (*Optional*) Enter an IP address range in **Allowed IPs** to restrict API access to the cluster. Leave empty to allow access from anywhere.
3. (*Optional*) Configure the **Maintenance window**:
* **Day**: Select the day of the week for scheduled maintenance from the drop-down list.
* **Start time (UTC)**: Enter the start time for the maintenance window in UTC.
{% endstep %}
{% step %}
### Save changes
Select **Edit cluster** to save your changes.
{% endstep %}
{% endstepper %}
{% hint style="success" %}
**Result:** The cluster is successfully updated.
{% endhint %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:
```
GET https://docs.ionos.com/cloud/containers/managed-kubernetes/how-tos/update-a-cluster.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.
Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
