AWS FIS 實驗範例範本

如果您使用 AWS FIS API 或命令列工具建立實驗範本，您可以在 JavaScript 物件標記法 (JSON) 中建構範本。若要取得有關實驗範本元件的更多資訊，請參閱〈〉範本元件。

若要使用其中一個範例範本建立實驗，請將其儲存至 JSON 檔案 (例如my-template.json)，將預留位置值以斜體取代為您自己的值，然後執行下列建立實驗範本命令。


aws fis create-experiment-template --cli-input-json file://my-template.json

根據篩選器停止 EC2 執行個體

下列範例會使用指定 VPC 中的指定標籤停止指定區域中所有執行中的 Amazon EC2 執行個體。它在兩分鐘後重新啟動它們。

停止指定數量的 EC2 執行個體

下列範例會停止具有指定標籤的三個執行個體。 AWS FIS 會選取要隨機停止的特定執行個體。會在兩分鐘後重新啟動這些執行個體。

}

執行預先定義的自動化手冊

下列範例會使用 AWS 發佈通知 Systems Manager 所提供的工作流程簿，將通知發佈至 Amazon SNS。角色必須具有將通知發佈至指定 SNS 主題的權限。


{
    "description": "Publish event through SNS",
    "stopConditions": [
        {
            "source": "none"

使用目標 IAM 角色調節 EC2 執行個體上的 API 動作

下列範例會限制動作定義中針對目標定義中指定的 IAM 角色進行的 API 呼叫所指定的 100% API 呼叫。

注意

如果您想要鎖定屬於 Auto Scaling 群組成員的 EC2 執行個體，請使用 aw:ec2: asg-不足-執行個體容量錯誤動作，並改為由 Auto Scaling 群組鎖定目標。如需詳細資訊，請參閱。
