## Gunicornによる公式Dockerイメージ - Uvicorn

前の章で詳しく説明したように、Uvicornワーカーで動作するGunicornを含む公式のDockerイメージがあります： [Server Workers - Gunicorn と Uvicorn](server-workers.md){.internal-link target=_blank}で詳しく説明しています。

このイメージは、主に上記で説明した状況で役に立つでしょう： [複数のプロセスと特殊なケースを持つコンテナ（Containers with Multiple Processes and Special Cases）](#containers-with-multiple-processes-and-special-cases)

	if source.noWait {
		select {
		case globalBackgroundHealRoutine.tasks <- task:
			if serverDebugLog {
				fmt.Printf("Task in the queue: %#v\n", task)
			}
		default:
			// task queue is full, no more workers, we shall move on and heal later.
			return nil
		}
		// Don't wait for result
		return nil
	}

	// respCh must be set to wait for result.
	// We make it size 1, so a result can always be written

   * cache size. The application needs to be aware of calling this function during the
   * initialization phase and preferably in a background worker thread.
   *
   * Note that if the application chooses to not call this method to initialize the cache. By
   * default, OkHttp will perform lazy initialization upon the first usage of the cache.

しかし、多くの場合、複数のワーカー・プロセスを同時に実行したいと考えるでしょう。

### 複数のプロセス - Worker

クライアントの数が単一のプロセスで処理できる数を超えており（たとえば仮想マシンがそれほど大きくない場合）、かつサーバーの CPU に**複数のコア**がある場合、同じアプリケーションで同時に**複数のプロセス**を実行させ、すべてのリクエストを分散させることができます。

同じAPIプログラムの**複数のプロセス**を実行する場合、それらは一般的に**Worker／ワーカー**と呼ばれます。

### ワーカー・プロセス と ポート

It is the recommended server for Starlette and **FastAPI**.

/// check | **FastAPI** recommends it as

The main web server to run **FastAPI** applications.

You can also use the `--workers` command line option to have an asynchronous multi-process server.

Check more details in the [Deployment](deployment/index.md){.internal-link target=_blank} section.

///

/// check | **FastAPI** lo recomienda como

El servidor web principal para ejecutar aplicaciones **FastAPI**.

También puedes usar la opción de línea de comandos `--workers` para tener un servidor multiproceso asíncrono.

   *       applies only to the task that was running at the point of interruption.
   *   <li>if the thread was interrupted before the SequentialExecutor's worker begins execution,
   *       the interrupt will be restored to the thread after it completes so that its {@code
   *       delegate} Executor may process the interrupt.

      <version>1.3.0</version>
    </dependency>
    ```

 *  **Fix: improve parallelism of async requests.** OkHttp's Dispatcher had a
    misconfigured `ExecutorService` that limited the number of worker threads.
    If you're using `Call.enqueue()` this update should significantly improve
    request concurrency.

 *  **Fix: Lazily initialize the response cache.** This avoids strict mode
