In the next chapter about [FastAPI in Containers - Docker](docker.md){.internal-link target=_blank} I'll explain some strategies you could use to handle the other **deployment concepts**.

I'll show you how to **build your own image from scratch** to run a single Uvicorn process. It is a simple process and is probably what you would want to do when using a distributed container management system like **Kubernetes**.

* `swagger_js_url`: the URL where the HTML for your Swagger UI docs can get the **JavaScript** file. **This is the one that your own app is now serving**.
* `swagger_css_url`: the URL where the HTML for your Swagger UI docs can get the **CSS** file. **This is the one that your own app is now serving**.

And similarly for ReDoc...

Bạn có thể tạo ra sản phẩm thực tế với **FastAPI** ngay bây giờ (và bạn có thể đã làm điều này trong một thời gian dài), bạn chỉ cần đảm bảo rằng bạn sử dụng một phiên bản hoạt động đúng với các đoạn mã còn lại của bạn.

## Cố định phiên bản của `fastapi`

Điều đầu tiên bạn nên làm là "cố định" phiên bản của **FastAPI** bạn đang sử dụng để phiên bản mới nhất mà bạn biết hoạt động đúng với ứng dụng của bạn.

        // Verify independence
        assertEquals(2, t1.numThreads, "t1 should have its own numThreads value");
        assertEquals(5, t2.numThreads, "t2 should have its own numThreads value");
        assertEquals("smb://server1/share/file.txt", t1.url, "t1 should have its own URL");
        assertEquals("smb://server2/share/file.txt", t2.url, "t2 should have its own URL");
    }

But if you want to use `async` / `await` without FastAPI, you can do it as well.
