### Base Docker Image { #base-docker-image }

Eskiden resmi bir FastAPI Docker image'ı vardı: [tiangolo/uvicorn-gunicorn-fastapi](https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker). Ancak artık kullanımdan kaldırıldı (deprecated). ⛔️

Aquí te mostraré cómo usar **Uvicorn** con **worker processes** usando el comando `fastapi` o el comando `uvicorn` directamente.

/// info | Información

Si estás usando contenedores, por ejemplo con Docker o Kubernetes, te contaré más sobre eso en el próximo capítulo: [FastAPI en Contenedores - Docker](docker.md).

/// info | Bilgi

Container kullanıyorsanız (örneğin Docker veya Kubernetes ile), bununla ilgili daha fazlasını bir sonraki bölümde anlatacağım: [Container'larda FastAPI - Docker](docker.md).

	workerSize, err := strconv.Atoi(env.Get("_MINIO_BATCH_EXPIRATION_WORKERS", strconv.Itoa(runtime.GOMAXPROCS(0)/2)))
	if err != nil {
		return err
	}

	wk, err := workers.New(workerSize)
	if err != nil {
		// invalid worker size.
		return err
	}

	ctx, cancelCause := context.WithCancelCause(ctx)
	defer cancelCause(nil)

	results := make(chan itemOrErr[ObjectInfo], workerSize)
	go func() {

   * 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.

**Container**, Docker veya Kubernetes ile ilgili bazı maddeler şimdilik çok anlamlı gelmiyorsa dert etmeyin.

Container image'ları, Docker, Kubernetes vb. konuları ilerideki bir bölümde daha detaylı anlatacağım: [Container'larda FastAPI - Docker](docker.md).

### Image Docker de base { #base-docker-image }

Il existait une image Docker officielle FastAPI : [tiangolo/uvicorn-gunicorn-fastapi](https://github.com/tiangolo/uvicorn-gunicorn-fastapi-docker). Mais elle est désormais dépréciée. ⛔️

## Mehrere Worker { #multiple-workers }

Sie können mehrere Worker mit der `--workers`-Befehlszeilenoption starten:
