nginxでhttpsリバースプロキシを構築し.Net Coreアプリを動かす

■ 前提条件 $dotnet run で http://localhost:5000にアクセスするとdotnetアプリが動作すること。
前回のブログnginxでリバースプロキシさせてDotnet Coreを動かすで一通りリバースプロキシが構築できていること。

■ nginxの設定
ngingxのconfigファイルを以下の通り作成する。
httpsでアクセスが来たら、localhost:5000にリバースプロキシする。

./nginx.conf

$ cat nginx.conf 
user www-data;
worker_processes auto;
pid /run/nginx.pid;
include /etc/nginx/modules-enabled/*.conf;

events {
	worker_connections 768;
	# multi_accept on;
}

  upstream helloapp{
    server 127.0.0.1:5000;
  }

  server {
      listen     80;
      server_name  localhost;
      index        index.html;
      root /var/www/html;
  }

  server {
      listen                    10443 ssl;
      server_name               localhost 127.0.0.1;

      ssl_protocols TLSv1 TLSv1.1 TLSv1.2 TLSv1.3; # Dropping SSLv3, ref: POODLE

        proxy_set_header Connection keep-alive;
      }
  }

}

./proxy_params

$ cat proxy_params
proxy_set_header Host $http_host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Forwarded-Proto $scheme;

./conf.d/app01.conf これは、暗号化なしの80→10080ポートフォワード

$ cat conf.d/app01.conf 
server {
    listen       10080;
    server_name  localhost 127.0.0.1;
    charset     utf-8;

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    location / {
      proxy_pass http://localhost:5000;
      proxy_http_version 1.1;
      proxy_set_header Upgrade $http_upgrade;
      proxy_set_header Connection keep-alive;
      proxy_set_header Host $host;
      proxy_cache_bypass $http_upgrade;
      proxy_set_header   X-Forwarded-For $proxy_add_x_forwarded_for;
      proxy_set_header   X-Forwarded-Proto $scheme;
    }
}

これで
　http://192.168.33.10:10080
　https://192.168.33.10:10443
　でアクセスするとOK。
SSLはかならず、httpsでアクセスすること。
httpでアクセスすると、「400 The plain HTTP request was sent to HTTPS port」エラーが発生する。
