Ruby on Rails Application Stack

Ruby on Rails 8.1.3.1 on Ruby 3.4.10 with Puma, MySQL 8.0, phpMyAdmin and Webmin. A starter app runs in production mode as an unprivileged user under systemd with Hotwire included - the Rails way to build the front end - and SECRET_KEY_BASE and the database password are regenerated for your instance at first boot.

Ruby on Rails Application Stack on AWS.

Microsoft Azure and Google Cloud are next on the roadmap. One clean-room build, one first-boot credential model, one patch cadence — identical on every cloud you run. Every identifier below is the real one; copy it and launch.

    AWS launch steps

Getting started

From launch to signed in, step by step.

  1. Launch in us-east-1 with TCP 22, 80, 3000 and 8000 open; wait for the health checks.

  2. Open http://<instance-public-ip>:3000 for the Rails app. phpMyAdmin: http://<instance-public-ip>/phpmyadmin (username root). Webmin: port 8000 (username admin or root). The password for both is your EC2 Instance ID (for example i-0123456789abcdef0).

  3. Deploy your app to /var/www/railsapp, keep config/database.yml reading ENV["RAILSAPP_DATABASE_PASSWORD"], then sudo systemctl restart railsapp - or point the unit's WorkingDirectory at your own path.

  4. Config lives in /etc/railsapp/env. rails-info prints URLs, versions and service status; sudo journalctl -u railsapp -f follows logs.

  5. SSH as ubuntu with your key pair. Change passwords with sudo bash /home/ubuntu/iscripts/pass_mysql.sh, pass_webmin.sh or pass_all.sh.

Security posture

What this image does and does not ship with, one fact per line.

  • Clean-room build on Canonical's official Ubuntu 24.04 LTS image: every component comes from its own official repository or release, nothing is copied from any third-party image, and the finished image was scanned for third-party vendor strings before capture.

  • No usable credential ships in the image; passwords are set on your instance at first boot from EC2 instance metadata (IMDSv2) and the scripts that set them delete themselves afterwards.

  • SSH is key-only, root login over SSH is refused, and build-time SSH keys, shell history and logs were removed before imaging.

  • First boot regenerates SECRET_KEY_BASE and the application database password for this instance, together with the phpMyAdmin cookie key - without that, a session forged on any instance would be accepted on all of them - and sets the MySQL root and Webmin passwords from the Instance ID.

  • MySQL automation uses a socket-authenticated account bound to OS root, so no stored password exists to be stripped and only a root process can use it.

  • The Rails app runs as the unprivileged rails user with its environment file mode 0640.

  • Rails 8's forced SSL is disabled in production.rb so the app answers at a bare IP; re-enable it once you have a certificate.

  • The bundled password tools enforce at least 10 characters with upper- and lower-case letters, a number and a symbol, and verify the new credential with a real sign-in before reporting success.

  • The image is HTTP-only by design so it works at a bare IP with no certificate warnings: terminate TLS at a load balancer or add a certificate before exposing it publicly, and restrict port 22 and any admin ports to trusted IP ranges in your security group.
