はじめに 以前、ECSタスク内でのコンテナ間通信について調べた際にNginxコンテナとGunicornコンテナを同一タスク内に構築してみました。 そのためタスク数を増やそうとした時にNginxコンテナとGunicornコンテナが1セットとして増えていくような構成となり、それぞれ個別にスケーリングすることができませんでした。 今回はNginxとGunicornはECSサービスを分けて構成し、それぞれのサービスが個別にスケーリングできるようにしていきます。 異なるECSサービスでのコンテナ間通信を実現するために「サービス検出」機能を使用したいと思います。 構成図 以下のような構成を目指します。 サービス検出関連の設定として下記を使用します。 名前空間名：local サービス名：ecs-django-gunicorn サービス検出の有効化 サービス検出はECSサービス単位で設定しますが、今回はG
Add and categorize all of your knowledge. Study anything that you want to learn and remember, or use search for instant access. Study more efficiently and remember better.
