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