根據篩選條件停止EC2執行個體停止指定數量的EC2執行個體執行預先設定 AWS FISSSM的文件執行預先定義的自動化 Runbook 具有目標IAM角色之EC2執行個體上的調節API動作 Kubernetes CPU 叢集中 Pod 的壓力測試

範例 AWS FIS實驗範本

如果您使用 AWS FISAPI或命令列工具來建立實驗範本，您可以在 JavaScript 物件標記 () 中建構範本JSON。如需實驗範本元件的詳細資訊，請參閱 AWS FIS 實驗範本元件。

若要使用其中一個範例範本建立實驗，請將其儲存到 JSON 檔案（例如，my-template.json)，將中的預留位置值取代italics為您自己的值，然後執行下列create-experiment-template命令。


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

根據篩選條件停止EC2執行個體

下列範例會停止指定區域中所有執行中的 Amazon EC2執行個體，並在指定的中具有指定的標籤VPC。它會在兩分鐘後重新啟動它們。
