I’ve been working on this for nearly two years. I originally aimed to complete it before my son was born, but he’s now 16 months old. Go figure. Seems like writing a book is harder than it looks. My original motivation was to write something I would want to read since most resources I found on self-hosting were either too shallow, lacked real-world examples like code, or didn’t fully address the knowledge gaps I kept running into.

The book starts with the basics and builds up to covering the full infrastructure stack, with the goal of understanding the system as a whole and eventually deploying on Kubernetes. Kubernetes is a major focus but the content can be applied to any environment. I can't express this clearly, but you should probably check the sample "Jobs and CronJobs" section to get an idea. There’s also a section on best practices, tips, and practical details based on things I’ve run into myself.

It is available for free including the PDF and the code blocks. Yet, you are welcome to pay what you want.
