Sparky is a demo Rails application

Frontend

Frontend files located in /public directory. Nginx exposes this content directly without requests to backend.

Backend

Backend upstream binded to /api namespace. It has two routes:

• POST /api/messages — receives message params and stores a record in PostgreSQL.
• GET /api/check — returns Hello world! string if application works correctly.

Puma

Puma is configured for binding with UNIX-socket.

Nginx config

HTTP/2 and SSL enabled.

upstream sparky {
  server unix:/path/to/sparky/shared/sockets/puma.sock;
}

server {
        ssl_certificate /etc/letsencrypt/live/sparky.rediron.ru/fullchain.pem; # managed by Certbot
        ssl_certificate_key /etc/letsencrypt/live/sparky.rediron.ru/privkey.pem; # managed by Certbot

        include snippets/ssl-params.conf;

        listen 443 ssl http2;
        listen [::]:443 ssl http2;

  server_name sparky.rediron.ru; # change to match your URL
  root /path/to/sparky/current/public; # I assume your app is located at that location

  error_log /var/log/nginx/sparky.rediron.ru-error.log;
  access_log /var/log/nginx/sparky.rediron.ru-access.log;
