standardmäßig jedes Mal diejenigen für **einen einzelnen Container** abrufen (für den Container, der den spezifischen Request verarbeitet hat), anstatt die **akkumulierten Metriken** für alle replizierten Container abzurufen.

In diesem Fall könnte einfacher sein, **einen Container** mit **mehreren Prozessen** und ein lokales Tool (z. B. einen Prometheus-Exporter) in demselben Container zu haben, welches Prometheus-Metriken für alle internen Prozesse sammelt und diese Metriken für diesen einzelnen...

A container image is comparable to the **program** file and contents, e.g. `python` and some file `main.py`.

    Wenn Sie Container verwenden, beispielsweise mit Docker oder Kubernetes, erzähle ich Ihnen mehr darüber im nächsten Kapitel: [FastAPI in Containern – Docker](docker.md){.internal-link target=_blank}.

!!! info
    If you are using containers, for example with Docker or Kubernetes, I'll tell you more about that in the next chapter: [FastAPI in Containers - Docker](docker.md){.internal-link target=_blank}.

    In particular, when running on **Kubernetes** you will probably **not** want to use Gunicorn and instead run **a single Uvicorn process per container**, but I'll tell you about it later in that chapter.

                termynals.push(termynal);
            });
    }

    function loadVisibleTermynals() {
        termynals = termynals.filter(termynal => {
            if (termynal.container.getBoundingClientRect().top - innerHeight <= 0) {
                termynal.init();
                return false;
            }
            return true;
        });
    }

!!! tip
    Don't worry if some of these items about **containers**, Docker, or Kubernetes don't make a lot of sense yet.

```console
$ docker build -t myimage .

---> 100%
```

</div>

### Inicie o container Docker

* Rode um container baseado em sua imagem:

<div class="termy">

```console
$ docker run -d --name mycontainer -p 80:80 myimage
```

</div>

Agora você tem um servidor FastAPI otimizado em um container Docker. Auto-ajustado para seu servidor atual (e número de núcleos de CPU).

### Verifique

In most cases you would (and should) have a "termination proxy" handling HTTPS for you on top, this will depend on how you deploy your application, your provider might do this for you, or you might need to set it up yourself.
