• Ruby 3.2.x
• Rails 7.0.x
• MongoDB (>5.0)
• Node.js (>18.x)

Unlike usual Rails system, this system uses MongoDB (through Mongoid) only. You don't need MariaDB(MySQL) or PostgreSQL.

credentials.yml should have MongoDB credentials.

mongodb:
  development:
    dbname: <development database name>
    user: <username>
    password: <password>
  test:
    dbname: <test database name>
    user: <username>
    password: <password>
  production:
    dbname: <production database name>
    user: <username>
    password: <password>

As is often the case with modern Rails, puma should start through systemd and a reverse proxy should be set up.
