FAQ
Is this book just for Rails?
Kamal is framework-independent and so I wrote the book in a general way, only mentioning assumptions about one's Dockerfile. Bring your Dockerfile and you are good.
Is this only for Ubuntu?
Kamal doesn't tie itself with any particular Linux flavor so you can use your favourite. The small provisioning examples in the book are tested against Ubuntu 22 LTS.
