使用 的 AWS CLI 命令建立 Amazon ECS 資源 AWS CloudFormation

下列教學課程說明如何使用 AWS CLI 建立具有 範本的 AWS CloudFormation Amazon ECS 資源。

先決條件

步驟 1：建立堆疊

若要使用 建立堆疊 AWS CLI，請遵循下列步驟。

  1. 使用您選擇的文字編輯器，建立名為 的檔案ecs-tutorial-template.yaml。

  2. 在 ecs-tutorial-template.yaml 檔案中，貼上下列範本並儲存變更。

  3. 建立範本檔案之後，請使用下列命令來建立堆疊。需要 --capabilities旗標才能建立範本中指定的 Amazon ECS 任務執行角色。您也可以指定 --parameters旗標來自訂範本參數。

    aws cloudformation create-stack \
      --stack-name ecs-stack \
      --template-body file://ecs-tutorial-template.yaml \
      --capabilities CAPABILITY_IAM

步驟 2：驗證資源建立

若要確保正確建立資源，請遵循下列步驟。您也可以檢查 Amazon ECS 主控台。

  1. 執行下列命令，列出 中的所有任務定義 AWS 區域。

    aws ecs list-task-definitions

    命令會傳回任務定義 Amazon Resource Name (ARN) 的清單。您使用範本建立之任務定義的 ARN 會以下列格式顯示。

    {
    "taskDefinitionArns": [
     .....
        "arn:aws:ecs:aws-region:111122223333:task-definition/task-definition-cfn:1",
     .....   
    ]
}

  2. 執行下列命令，列出 中的所有叢集 AWS 區域。

    aws ecs list-clusters

    命令會傳回叢集 ARNs的清單。您使用範本建立的叢集 ARN 會以下列格式顯示。

    {
    "clusterArns": [
        .....
        "arn:aws:ecs:aws-region:111122223333:cluster/CFNCluster",
        .....
    ]
}

  3. 執行下列命令，列出叢集 中的所有服務CFNCluster。

    aws ecs list-services \
      --cluster CFNCluster

    命令會傳回服務 ARNs的清單。您使用範本建立的服務 ARN 會以下列格式顯示。

    {
    "serviceArns": [
        "arn:aws:ecs:aws-region:111122223333:service/CFNCluster/cfn-service"
    ]
}

步驟 3：清理

若要清除您建立的資源，請執行下列命令。

aws cloudformation delete-stack \
      --stack-name ecs-stack

delete-stack 命令會啟動刪除在本教學課程中建立的 AWS CloudFormation 堆疊，刪除堆疊中的所有資源。若要驗證刪除，您可以重複 中的程序步驟 2：驗證資源建立。輸出中的 ARNs 清單將不再包含名為 的任務定義task-definition-cfn或名為 的叢集CFNCLuster。list-services 呼叫將會失敗。
