AlibabaCloudのAuto Scaling x SLB x RDSをやってみる(ROS版)
はじめに
AlibabaCloudのAuto Scaling x SLBをやってみる(ROS版)
でやった、テンプレートにRDSを追加してみます。
JSONテンプレート
こちらのテンプレートで起動が可能です。

はまったところ
mysql.n1.micro.1
rds.mssql.s2.large
でやっていたら全然起動できない状態になりました。
下記のようなエラーコードがでました。
Resource CREATE failed: 〜〜〜〜〜 RequestId: XXXXXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXX
とかエラーがでて、長い間はまってました。
調べた結果
インスタンスタイプリスト - プロダクト紹介| Alibaba Cloud ドキュメントセンター
と照らし合わせて、起動するRDSに適したインスタンスタイプにしないとダメでした。
ここは今後詳しくしらべてまとめたいと思います。
まとめ
サンプルテンプレートに
ess_1slb_2rds_2ecs
というものがありました。
こちらを起動しても、今回に近しい構成になります。
学習してきた結果として、そこに行き着いたので
いままでの記事を逆に辿れば、どこをやっていけばいいのかポイントがわかりやすくなると思います。
