-Add external database details to your `values.yaml` file. This disables the default internal Postgres database (`airbyte/db`), and configures your external Postgres database. You can override all of the values below by setting them in the airbyte-config-secrets or set them directly in the `values.yaml` file. **The database password is a special case in that it must be set in the [airbyte-config-secrets](#secrets).**
