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.
PDF isn't optimized for that, like now, reading the article a phone, I couldn't properly check out a chapter because PDF is awful in optimizing itself for a smaller screen
Had to search but it seems that lulu allows 800 pages so your book can fit just right in
There are definitely some other publishers like No Starch Press who might help ya as well.
Since I spend so much time, I decided to let people read it.
Thanks for creating this book!
