```Dockerfile
CMD ["uvicorn", "app.main:app", "--proxy-headers", "--host", "0.0.0.0", "--port", "80"]
```

#### Docker-Cache

In diesem `Dockerfile` gibt es einen wichtigen Trick: Wir kopieren zuerst die **Datei nur mit den Abhängigkeiten**, nicht den Rest des Codes. Lassen Sie mich Ihnen erklären, warum.

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```

#### Docker Cache

There's an important trick in this `Dockerfile`, we first copy the **file with the dependencies alone**, not the rest of the code. Let me tell you why is that.

```Dockerfile
COPY ./requirements.txt /code/requirements.txt
```

   *
   * But the methods in this class want to throw different exceptions, depending on the args, so it
   * appears that this pattern is not directly applicable. But we can use the ridiculous, devious
   * trick of throwing an exception in the middle of the construction of another exception. Hotspot
   * is fine with that.

                the OpenAPI version. But some tools, even though they might be
                compatible with OpenAPI 3.1.0, might not recognize it as a valid.

                So you could override this value to trick those tools into using
                the generated OpenAPI. Have in mind that this is a hack. But if you
                avoid using features added in OpenAPI 3.1.0, it might work for your
                use case.
