sie *beim Speichern generiert*. SQLModel versteht, dass die Datenbank die `id` bereitstellt, und *definiert die Spalte im Datenbankschema als ein Nicht-Null-`INTEGER`*.

Para isso, primeiro importe:

* `Annotated` de `typing`

    Esse é o diretório onde colocaremos o arquivo `requirements.txt` e o diretório `app`.

3. Copie o arquivo com os requisitos para o diretório `/code`.

    Copie **somente** o arquivo com os requisitos primeiro, não o resto do código.

    Como esse arquivo **não muda com frequência**, o Docker irá detectá-lo e usar o **cache** para esse passo, habilitando o cache para o próximo passo também.
