Se seu arquivo for nomeado `main.py`, execute sua aplicação com:

<div class="termy">

```console
$ fastapi dev main.py

<span style="color: green;">INFO</span>:     Uvicorn running on http://127.0.0.1:8000 (Press CTRL+C to quit)

</div>

* The **HTTPS certificates** "certify" a **certain domain**, but the protocol and encryption happen at the TCP level, **before knowing** which domain is being dealt with.
* **By default**, that would mean that you can only have **one HTTPS certificate per IP address**.
    * No matter how big your server is or how small each application you have on it might be.
    * There is a **solution** to this, however.

# (1)
COPY ./main.py /code/

# (2)
CMD ["uvicorn", "main:app", "--host", "0.0.0.0", "--port", "80"]
```

1️⃣. 📁 `main.py` 📁 `/code` 📁 🔗 (🍵 🙆 `./app` 📁).

2️⃣. 🏃 Uvicorn & 💬 ⚫️ 🗄 `app` 🎚 ⚪️➡️ `main` (↩️ 🏭 ⚪️➡️ `app.main`).

⤴️ 🔆 Uvicorn 📋 ⚙️ 🆕 🕹 `main` ↩️ `app.main` 🗄 FastAPI 🎚 `app`.
