# Customize Deployment release names

An Airflow Deployment's release name on Astro Private Cloud is a unique, immutable identifier for that Deployment. The release name corresponds to its Kubernetes namespace and that renders in Grafana and other platform-level monitoring tools.

By default, release names are randomly generated in the following format: `noun-noun-<4-digit-number>`. For example: `elementary-zenith-7243`. Alternatively, you can customize the release name for a Deployment if you want all namespaces in your cluster to follow a specific style.

To customize the release name for a Deployment as you're creating it, you first need to enable the feature on your Astro Private Cloud platform. To do so, set the following value in your `values.yaml` file:

```yaml wrap theme={null}
astronomer:
  houston:
    config:
      deployments:
        manualReleaseNames: true # Allows you to set your release names
```

Then, push the updated `config.yaml` file to your installation as described in [Apply a config change](/docs/astro-private-cloud/v-2-x/apply-platform-config).

After applying this change, the **Release Name** field in the Astro Private Cloud UI becomes configurable.
