タグを指定するだけでRDSを自動起動・停止する

Posted at

はじめに

タグを指定するだけでEC2インスタンスを自動起動・停止する」のRDS版です。

案件で必要になったためメモを残しておきます。

やりたいこと

RDSタグにStartTime:8am、StopTime:9pmを設定すると朝8時に自動起動、夜9時に自動停止させます。

手順は前回と全く同じなのでドキュメントのコンテンツだけの記事です。

注意点

タグに対応するDB識別子が取得できない場合、SSMAutomationは失敗します。
つまりCloudWatchRulesに7amに起動するルールを設定したとしてもRDSにStartTime:7amに対応するルールがないと失敗してしまうのでその点だけご注意ください。
