下記の記事にて AWS ChatbotがSlackからのコマンド実行をβ版サポートしたとのことで、早速試しました

画像キャプチャなどもある対応方法は下記のブログ記事で確認したので、操作手順は下記を参照してください。※英語ですが、、、、

Running AWS commands from Slack using AWS Chatbot | AWS DevOps Blog

上記ブログの「2. Test AWS Chatbot in Slack and get help」のところまできて、 `@aws help` を実行してみたところ

１つのSlack内で複数のAWSアカウントのAWS Chatbotを利用している場合なんでしょうか。最初にどちらのAWSアカウントをデフォルトアカウントとして、利用するかを確認されました。
マスキングしてますが、アカウントIDの書かれた２つのボタンが表示されてボタンを押すだけです。

その後、 @aws help したところ上記ブログと同様のレスポンスがかえってきました

aws cliとほぼ似たようなコマンドで対応できるので、わかりやすいですね
取り急ぎ、EC2まわりを試したいので、 @aws ec2 --help してみたところ、結構いろんなコマンドがでてきました。

コマンド多すぎてやばい・・・
ついでに、 @aws ec2 describe-instance --region ap-northeast-1 してみたら、結構表示が細かい情報まで表示される仕組みのようで、
「Show more」も出るしで、インスタンスがたくさんあると大変そうでした・・・もう少し見やすい表示にならないかなー

まとめ

まあまだ導入したばかりなので、もっと使い倒してみます。その流れで NoOpsが加速するといいですね
lambda使えたりとか、サポートへ質問できたりもするみたいなので、便利そうですね。
サポートへ質問できるところはSlackの /feedback と同じようにしてたくさん意見もらえるようにしたのかなー
