### Create the `Settings` object

Import `BaseSettings` from Pydantic and create a sub-class, very much like with a Pydantic model.

The same way as with Pydantic models, you declare class attributes with type annotations, and possibly default values.

## Tính năng của Starlette

`FastAPI` is thực sự là một sub-class của `Starlette`. Do đó, nếu bạn đã biết hoặc đã sử dụng Starlette, đa số các chức năng sẽ làm việc giống như vậy.

Với **FastAPI**, bạn có được tất cả những tính năng của **Starlette**:

				if atomic.LoadInt32(&c.connected) == closed {
					return
				}
				if c.HealthCheckFn() {
					if atomic.CompareAndSwapInt32(&c.connected, offline, online) {
						now := time.Now()
						disconnected := now.Sub(c.LastConn())
						logger.Event(context.Background(), "healthcheck", "Client '%s' re-connected in %s", c.url.String(), disconnected)
						atomic.StoreInt64(&c.lastConn, now.UnixNano())
					}
					return
				}

This has two implementations:
* The Credentials controller is responsible for reading TLS certificates, stored as Secrets.
* The Kubernetes Service Discovery controller is a bit of a monolith, and spins off a bunch of other sub-controllers in addition to the core service discovery controller.

Because of the monolithic complexity it helps to see this magnified a bit:
