!!ロール作成
カレンダの状態取得とEC2(or RDS)の起動と終了ができるロール作成
上記で作成したポリシーを持ったロールを作成

!!カレンダ作成
https://ap-northeast-1.console.aws.amazon.com/systems-manager/change-calendar?region=ap-northeast-1
から新しいカレンダ作成。
今回はカレンダに予定がある日は「実行しない」とするので「デフォルトで開く」のカレンダを作成

!!!ドキュメント作成
!!RDS
既存のRDS起動のドキュメントをクローンして作成する。
ステップ1で指定されたカレンダのチェックを追加
  description: Start RDS instance
  schemaVersion: '0.3'
  assumeRole: '{{ AutomationAssumeRole }}'
  parameters:
    InstanceId:
      type: String
      description: (Required) RDS Instance Id to start

      description: (Optional) The ARN of the role that allows Automation to perform the actions on your behalf.
      default: ''
    CalendarName:
      type: String
      description: '(Required) CalendarName (arn:aws:ssm:ap-northeast-1:xxxxxxx:xxxxxxxx)'

!!!メンテナンスウインドウ作成
https://ap-northeast-1.console.aws.amazon.com/systems-manager/maintenance-windows?region=ap-northeast-1
