So, in this case, you **would not** want to have a process manager like Gunicorn with Uvicorn workers, or Uvicorn using its own Uvicorn workers. You would want to have just a **single Uvicorn process** per container (but probably multiple containers).

Underneath, the `open("./somefile.txt")` creates an object that is called a "Context Manager".

When the `with` block finishes, it makes sure to close the file, even if there were exceptions.

When you create a dependency with `yield`, **FastAPI** will internally create a context manager for it, and combine it with some other related tools.

### Using context managers in dependencies with `yield`

!!! warning

# Abhängigkeiten mit yield

FastAPI unterstützt Abhängigkeiten, die nach Abschluss einige <abbr title="Manchmal auch genannt „Exit Code“, „Cleanup Code“, „Teardown Code“, „Closing Code“, „Kontext Manager Exit Code“, usw.">zusätzliche Schritte ausführen</abbr>.

Verwenden Sie dazu `yield` statt `return` und schreiben Sie die zusätzlichen Schritte / den zusätzlichen Code danach.

!!! tip "Tipp"
    Stellen Sie sicher, dass Sie `yield` nur einmal pro Abhängigkeit verwenden.

  // If not specified, this will default to the time zone of the kube-controller-manager process.
  // The set of valid time zone names and the time zone offset is loaded from the system-wide time zone
  // database by the API server during CronJob validation and the controller manager during execution.
  // If no system-wide time zone database can be found a bundled version of the database is used instead.
