A partir daí, perto do final do `Dockerfile`, copiamos todo o código. Como isso é o que **muda com mais frequência**, colocamos perto do final, porque quase sempre, qualquer coisa depois desse passo não será capaz de usar o cache.

```Dockerfile
COPY ./app /code/app
```

            Thread t = new Thread(r, "LeaseManager-Cleanup");
            t.setDaemon(true);
            return t;
        });

        // Schedule periodic cleanup
        long cleanupInterval = context.getConfig().getLeaseTimeout();
        if (cleanupInterval <= 0) {
            cleanupInterval = DEFAULT_LEASE_CLEANUP_INTERVAL;
        }

## URL de OpenAPI

Por defecto, el esquema OpenAPI se sirve en `/openapi.json`.

Pero puedes configurarlo con el parámetro `openapi_url`.

Por ejemplo, para configurarlo para que se sirva en `/api/v1/openapi.json`:

{* ../../docs_src/metadata/tutorial002.py hl[3] *}

    * Sistemas de generación automática de código cliente, para muchos lenguajes.
* Proporcionará 2 interfaces web de documentación interactiva directamente.

Solo tocamos los conceptos básicos, pero ya te haces una idea de cómo funciona todo.

Intenta cambiar la línea con:

```Python
    return {"item_name": item.name, "item_id": item_id}
```

...desde:

```Python

	_ Format = (1 << iota) / 4 // Sequence of 0, 0, 1, 2, 4, 8, etc...

	// FormatUnknown indicates that the format is unknown.
	FormatUnknown

	// The format of the original Unix V7 tar tool prior to standardization.
	formatV7

	// FormatUSTAR represents the USTAR header format defined in POSIX.1-1988.
	//
	// While this format is compatible with most tar readers,

También podrías usar `from starlette.testclient import TestClient`.

**FastAPI** proporciona el mismo `starlette.testclient` como `fastapi.testclient` solo por conveniencia para ti, el desarrollador. Pero proviene directamente de Starlette.
