그렇다면 여러분은 **프로세스 매니저**와 함께 내부에 **몇개의 워커 프로세스들**을 시작하는 **단일 컨테이너**를 필요로 할 수 있습니다.

#### Prometheus와 다른 이유들

여러분은 **단일 프로세스**를 가지는 **다중 컨테이너** 대신 **다중 프로세스**를 가지는 **단일 컨테이너**를 채택하는 **다른 이유**가 있을 수 있습니다.

예를 들어 (여러분의 장치 설정에 따라) Prometheus 익스포터와 같이 같은 컨테이너에 들어오는 **각 요청에 대해** 접근권한을 가지는 도구를 사용할 수 있습니다.

その場合、**単一のコンテナ**で、**プロセスマネージャ**が内部で**複数のワーカープロセス**を起動するようにします。

#### Prometheusとその他の理由

また、**1つのコンテナ**に**1つのプロセス**を持たせるのではなく、**1つのコンテナ**に**複数のプロセス**を持たせる方が簡単だという**他の理由**もあるでしょう。

例えば、(セットアップにもよりますが)Prometheusエクスポーターのようなツールを同じコンテナ内に持つことができます。

この場合、**複数のコンテナ**があると、デフォルトでは、Prometheusが**メトリクスを**読みに来たとき、すべてのレプリケートされたコンテナの**蓄積されたメトリクス**を取得するのではなく、毎回**単一のコンテナ**（その特定のリクエストを処理したコンテナ）のものを取得することになります。

		info.Metrics.TotalErrorsAvailability = p.totalErrsAvailability.Load()
		if p.health.isFaulty() {
			// if disk is already faulty return faulty for 'mc admin info' output and prometheus alerts.
			return info, errFaultyDisk
		}
		return info, nil
	}

	defer func() {
		if opts.Metrics {
			info.Metrics = p.getMetrics()
		}
		info.Metrics.TotalWrites = p.totalWrites.Load()
