My Rails 7.0 application is now deployed using Kamal to a single Digital Ocean droplet running:
- Rails
- Sidekiq
- PostgreSQL
- Redis.
⌛️Time spent: 5 hours.
I'll need to spend a bit more time with Kamal and hopefully there will be some lessons learned to share.

My notes from DHH's Rails World keynote📒
- Rails is 20 years old (2003-2023)
- DHH is 44 years old, spending halt the life on Rails
- We should be Renaissance Developers, caring about it all from frontend to backend and delivery
- DHH's second favourite language is JavaScript

Prediction:
Frameworks like React, Vue, and Svelte compiler will take a back seat.
A lot of the "frontend" can be now done easily from the backend thanks to Hotwire, StimulusReflex or LiveView.

Kamal Handbook is about Kamal which is in Ruby.
It's made with Asciidoc which is in Ruby.
I use foreman to build it which is in Ruby.
I sell it on Gumroad which is in Ruby.
Gumroad processes payments with Stripe which is in Ruby.
What a Ruby stack 💎😍

Deploying Ruby on Rails on a single server with Kamal:

✅ Having a mounted volume or a simple directory for a local disk service

Kamal is basically these 5 things:
- Bash (your hooks)
- YAML (your config definition)
- Ruby (Kamal is a gem)
- Traefik (load balancer)
- Docker (your process manager)
I really appreciate that Kamal is OS-agnostic.

Adding slugs and UUIDs to hide the real numeric IDs is pretty easy in Rails.
Personally I don't replace primary keys (they are fast and they can stay).
Instead I just redefine "to_param" on a model.
This is my Sluggable module for example:

Deploying with Kamal is hard at the moment:
1, not enough community resources
2. not great docs
3. I am getting flagged on Traefik forum for a Kamal related post
Luckily I solved my own problem in the end and I will put out more Kamal knowledge as I learn.
Fingers crossed🤞

Lots of people are asking. Yes, Kamal Handbook will get a new edition for Kamal 2.0 shortly after the official release.
Kamal 2 is getting close. Huge upgrade coming. Support for multiple apps on a single server, auto-provisioning of Let's Encrypt SSL certs, better secrets, faster deploys, aliases, and much more. This is the key to unlocking amazing deployment on any VPS / bare metal box.

Makes no sense. I would:

So I would have two. Email + most popular single sign-on relevant to my app.
