The Complete Guide to Deploying Rails 8 with Kamal on Hetzner | Mooktakim Ahmed

This is a complete, end-to-end guide to deploying a Rails 8 application with the Solid stack using Kamal on a Hetzner dedicated server. We will go from ordering a server to running your app in production with background jobs, backups, and monitoring. Assumptions: You have a Rails 8 application ready to deploy. Your app uses SQLite with the Solid stack (Solid Queue, Solid Cache, Solid Cable) — the default for new Rails 8 apps. Server requirements: A dedicated server or VPS with at least 2 GB of RAM. We will use Hetzner, but these instructions work with any provider (DigitalOcean, Vultr, OVH, etc.) — you just need a server running Ubuntu with SSH access.
