Developer focused content

You will deploy a production grade Flask application backed by a Redis database. To the point, no fluffy theory that what's needed

Hands on examples

Every concept is backed by at least 1 example, and an exercise where you can test your understanding, rather than just reading pages showing you how it's done.

You'll work with a real Kubernetes cluster from day 1.

6. Students and Educators: Students learning about cloud computing, containerization, and microservices architecture, as well as educators looking for resources to teach these concepts with practical Python examples.

Whom is this book NOT for?

If you already know Kubernetes and are using it in some capacity, then you might not find any value in this book. Also, if you don't have much of a technical background(don't know how to work with Python, no idea about containers), then this book won't be a good fit for you.

Who am I to write a book about Kubernetes for developers?

I'm a full stack developer with more than 2 decades of experience working with enterprise customers. I've been dabbling with Kubernetes since 2018, when there were comparitively lesser resources to tame the Kubernetes beast. I always wanted to read a book to bridge the knowledge gap for a developer who knows a bit of ops and wants to dip their toes in the Kubernetes waters and figured I'll write one for those who are on the same boat.

Is the book ideal only for Python developers? I'm a Node.js/Java/PHP/Rails/Golang/Rust developer.

The book has been written using a Python Flask application as an example. It is quite easy to fit in your stack if you understand the concepts explained in the book.

Please get in touch with me if you'd like to see the examples in your language.

When is the book available for purchase?
