/
協調器
這個元件負責啟動、停止與管理容器程序。這項技術通常稱為容器基礎架構即服務
（container infastructure as a service，ClaaS）， 在 Docker 生態系統中，通常是由
Docker Swarm 或 Kubernetes 提供的。
儲存器
儲存 app 資料。它可能是可以對映到容器裡面的區塊儲存器，或可用來儲存二進位

服務
資料庫與外部中介軟體服務，它們相當於傳統基礎設施的同類項目，但是通常是容
器平台供應商提供的全代管服務。
持續交付服務
許多容器平台供應商都提供完整的解決方案，可將程式碼從本地開發環境一路送到
生產環境。例如，Docker Enterprise 提供一種與它的 Docker Hub 整合的解決方案，
Azure 提供 Azure Pipelines，AWS ECS 提供 CodeBuild 與 CodePipeline ...
