使用 建立 Amazon ECS 資源 AWS CloudFormation

Amazon ECS 已與 整合 AWS CloudFormation,這項服務可讓您使用定義的範本來建立和設定 AWS 資源的模型。如此一來,您可以花更少的時間建立並管理資源和基礎設施。使用 AWS CloudFormation,您可以建立範本來描述您想要的所有 AWS 資源,例如特定的 Amazon ECS 叢集。然後, AWS CloudFormation 會負責佈建和設定這些資源。

使用 時 AWS CloudFormation,您可以重複使用範本,以一致且可重複的方式設定 Amazon ECS 資源。您會描述您的資源一次,然後在多個 AWS 帳戶 和 之間再次佈建相同的資源 AWS 區域。

AWS CloudFormation 範本

若要為 Amazon ECS 和相關服務佈建和設定資源,請確定您熟悉 AWS CloudFormation template. AWS CloudFormation templates 是 JSON 或 YAML 格式的文字檔案,其描述您想要在 AWS CloudFormation 堆疊中佈建的資源。如果您不熟悉 JSON 或 YAML 格式,或兩者都熟悉,您可以使用 AWS CloudFormation 設計工具開始使用 AWS CloudFormation 範本。如需詳細資訊,請參閱AWS CloudFormation 《 使用者指南》中的什麼是 AWS CloudFormation 設計工具?

Amazon ECS 支援在 AWS CloudFormation中建立叢集、任務定義、服務和任務集。下列範例示範如何使用 AWS CLI來以範本建立資源。您也可以使用 AWS CloudFormation 主控台建立這些資源。如欲進一步了解如何使用 AWS CloudFormation 主控台建立資源,請參閱 AWS CloudFormation 使用者指南

範例範本

使用獨立堆疊建立 Amazon ECS 資源

下列範例示範如何為每個資源使用獨立堆疊來建立 Amazon ECS 資源。

任務定義

您可以使用下列範本來建立 Fargate Linux 任務。

使用 從範本 AWS CLI 建立資源

下列指令會使用名為 ecs-template-body.json 的範本內文檔,建立一個名為 ecs-stack 的堆疊。請確定範本內文檔為 JSON 或 YAML 格式。檔案的位置已指定於 --template-body 參數。在此情況下,範本內文檔位於目前的目錄。

aws cloudformation create-stack \ --stack-name ecs-stack \ --template-body file://ecs-template-body.json

若要確保正確建立資源,請檢查 Amazon ECS 主控台,或使用下列指令:

  • 下列指令可列出所有任務定義。

    aws ecs list-task-definitions
  • 下列指令可列出所有叢集。

    aws ecs list-clusters
  • 下列指令可列出叢集 CFNCluster 中定義的所有服務。將 CFNCluster 替換為您要在其中建立服務的叢集名稱。

    aws ecs list-services \ --cluster CFNCluster
