aws CodeDeployによりデプロイ失敗調査メモ

CodeDeployを使ってデプロイを行ってみましたが、失敗しました。調査した経過をメモしておきます。

まず、Console上のエラーを確認します。
The overall deployment failed because too many individual instances failed deployment, too few healthy instances are available for deployment, or some instances in your deployment group are experiencing problems.
それをみてもよくわからないので、EC2にログインして、codedeployエージェントのログを確認します。

>less /var/log/aws/codedeploy-agent/codedeploy-agent.log

そしたら、以下のようなエラーが大量に出力されてました。

どうやっらインスタンスから外部に接続が失敗したようです。

ping google.co.jp

案の定失敗しました。ネットワーク接続を確認したとろこ、ルートテーブルの設定が足りてなかったです。ルートを追加したらうまくインテーネットに接続ができて、デプロイもできるようになりました。
