為 Amazon ECS Auto Scaling 群組設定預先初始化的執行個體

將下列 IAM 政策新增至您的容器執行個體角色，以允許執行個體完成生命週期動作：

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": [
                "autoscaling:CompleteLifecycleAction"
            ],
            "Resource": "*"
        }
    ]
}

在執行個體上使用 啟動時，將生命週期掛鉤新增至 Auto Scaling 群組ABANDON做為預設結果，並新增活動訊號逾時，以允許足夠的時間進行 Amazon ECS 初始化 （例如 10 分鐘）。如需詳細資訊，請參閱 Amazon EC2 Auto Scaling 使用者指南中的新增 lifecycle hook。

使用下列使用者資料來建立排程任務，以在延遲後完成生命週期動作。延遲可確保 EC2Launch 在執行個體停止之前完成儲存其狀態。將 MyCluster、my-lifecycle-hook 和 my-asg-name 取代為您的值。
