nginx http/3を動かす | デバッグライフ

NginxでHTTP/3を動かしてみます。HTTP/3はQUICというプロトコルに基づいているようです。詳しくは理解していないので追々学んでいきたいと思います。まずは、ローカルで動かしてどのようなデータやり取りが行われているのかwiresharkで覗くところから。

Dockerコンテナでビルドします。gistでレシピが公開されているのでそれに倣います。

ビルドすると以下のエラーとなってしまいました。

#13 58.57 auto/configure: error: invalid option "--with-http_quic_module"

1	#13 58.57 auto/configure: error: invalid option "--with-http_quic_module"

どうも上記のオプションは--with-http_v3_moduleに統合された？ようなので削除します。

参考：　https://hg.nginx.org/nginx-quic/rev/33226ac61076

最終的に以下のようにしました。
