Then the next concepts to consider are all about the program running your actual API (e.g. Uvicorn).

## Program and Process { #program-and-process }

We will talk a lot about the running "**process**", so it's useful to have clarity about what it means, and what's the difference with the word "**program**".

# (5)!
COPY ./app /code/app

# (6)!
CMD ["fastapi", "run", "app/main.py", "--port", "80"]
```

1. Inicie a partir da imagem base oficial do Python.

2. Defina o diretório de trabalho atual para `/code`.

    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`.

#### `Hero` - the *table model* { #hero-the-table-model }

Then let's create `Hero`, the actual *table model*, with the **extra fields** that are not always in the other models:

* `id`
* `secret_name`
