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. Do not commit the values.
4. Point each Service connection secret at stateful-web-app-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.
