# Adding a New Region to an Existing Deployment

You can add a new region to an already deployed setup using the `airctl`. This allows you to expand your environment without redeploying the entire system.

### Steps to Add a New Region

1. Update the Configuration File:

Edit the `airctl-config.yaml` file and append the new region name under the `duRegion` field. Example:

{% tabs %}
{% tab title="Bash" %}

```bash
# cat /opt/pf9/airctl/conf/airctl-config.yaml | grep -i region
duRegion: Infra RegionOne NewRegion
```

{% endtab %}
{% endtabs %}

2. Run the add-Region Command:

{% tabs %}
{% tab title="Bash" %}

```bash
airctl add-region --config /opt/pf9/airctl/conf/airctl-config.yaml
```

{% endtab %}
{% endtabs %}

3. Verify the Region Addition:

Once the command completes, verify that the new region has been successfully added. You should now see the newly added region reflected in both the **state file** and the **`airctl status`** output.

{% tabs %}
{% tab title="Bash" %}

```bash
airctl status --config /opt/pf9/airctl/conf/airctl-config.yaml
```

{% endtab %}
{% endtabs %}

Here is the sample output.

{% tabs %}
{% tab title="Bash" %}

```bash

------------- deployment details ---------------

```

{% endtab %}
{% endtabs %}

{% tabs %}
{% tab title="Bash" %}

```bash
# cat .airctl/state.yaml
...
regions:
    - name: Infra
      fqdn: airctl-1-4108764-426.platform9.localnet
      dbHostname: percona-db-pxc-db-haproxy.foo.svc.cluster.local
      dbPassword: *********
    - name: RegionOne
      fqdn: airctl-1-4108764-426-regionone.platform9.localnet
      dbHostname: percona-db-pxc-db-haproxy.foo-regionone.svc.cluster.local
      dbPassword: *********
    - name: NewRegion
      fqdn: airctl-1-4108764-426-newregion.platform9.localnet
      dbHostname: percona-db-pxc-db-haproxy.foo-regionone.svc.cluster.local
      dbPassword: *********
```

{% endtab %}
{% endtabs %}

This process ensures a seamless addition of new regions to your deployment while maintaining consistency across configuration and runtime state.

## 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.platform9.com/private-cloud-director/2026.1/getting-started/self-hosted/airctl/adding-a-new-region.md?ask=<question>&goal=<endgoal>
```

`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.
