概要

現在、DjangoでWebアプリケーションを作るにあたり、DockerとH2O、MariaDBを使ってdocker-compose環境を構築しています。

発生したエラー

H2OとGunicornでUNIXソケットを使って繋ぐ方法を試しているのですが、ファイルが見つからないというエラーが出てGunicornが起動しません。
エラーのログは以下の通りです。

他の起動手段を試しても、同様のエラーが繰り返し表示されます。

コード

なお、このコードはGitHubのリポジトリ https://github.com/huideyeren/e-koto-3-server にあげてあります。

H2Oのコンテナはフォークしたリポジトリ https://github.com/huideyeren/h2o-proxy-letsencrypt を使っています。

とりわけ、 docker-compose.yml は以下のようになっています。

YAML

自己解決

Dockerの問題で、UNIXドメインソケットを生成するパスを /var/sock/gunicorn に変えたら動きました。

docker-compose.yml は以下の通りです。
