Das Wichtigste ist, dass **FastAPI** durch die Verwendung von Standard-Python-Typen an einer einzigen Stelle (anstatt weitere Klassen, Dekoratoren usw. hinzuzufügen) einen Großteil der Arbeit für Sie erledigt.

5. Kopiere das Verzeichnis `./app` in das Verzeichnis `/code`.

    Da hier der gesamte Code enthalten ist, der sich **am häufigsten ändert**, wird der Docker-**Cache** nicht ohne weiteres für diesen oder andere **folgende Schritte** verwendet.

    Daher ist es wichtig, dies **nahe dem Ende** des `Dockerfile`s zu platzieren, um die Erstellungszeiten des Containerimages zu optimieren.

    // create a null output stream
    OutputStream nos = ByteStreams.nullOutputStream();
    // write to the output stream
    nos.write('n');
    String test = "Test string for NullOutputStream";
    byte[] bytes = test.getBytes(US_ASCII);
    nos.write(bytes);
    nos.write(bytes, 2, 10);
    nos.write(bytes, bytes.length - 5, 5);
    // nothing really to assert?
