These are separate files in one repository. A shared Docker network works only when the workloads run on the same server; Towbar does not automatically order their deployments or copy secret values between them.

## Configure

1. Register and prepare the example server or servers, connect the repository, and map `production` to the branch containing these files.
2. Save each Datastore credential value under **Datastore → Settings → Secrets**, deploy it first, and verify engine readiness before starting a dependent Service.
3. Save the Service's declared keys in its selected environment, or enable and authorize the selected [external-secret provider](/docs/secrets/external). Do not commit the values.
4. Point each Service connection secret at `api-with-a-daily-report-postgres` on the database engine's private port. The server and network must match; credentials are saved separately for each Service.
5. Sync the repository, inspect the resolved configuration, deploy manually, and perform the verification below before enabling automation.

## Verify

The command is present, bounded, and safe to rerun.

For field constraints, see [Service manifest](/docs/services/manifest) and [Datastore manifest](/docs/datastores/manifest).
