Last year I published a book, and I liked the experience, so I wrote another!
The book is called Hands-On Docker for Microservices with Python, and it goes through the different steps to move from a Monolith Architecture towards a Microservices one.
It is written from a very practical stand point, and aims to cover all the different elements involved. From the implementation of a single RESTful web microservice programmed in Python, containerise it in Docker, create a CI pipeline to ensure that the code is always high quality, and deploy it along with other Microservices in a Kubernetes cluster.
Most of the examples are to be run locally, but a chapter is included to create a Kubernetes cluster in the cloud using AWS services. There’s also other chapters dealing with production related issues, like observability or handling secrets.
Other than talking about technologies, like Python, Docker and Kubernetes; or techniques like Continuous Integration or GitOps; I also talk about the different challenges that teams and organisations face on the adoption of Microservices. And how to structure the work properly to reduce problems.
I think the book will be useful for people dealing with these problems, or thinking to make the move. Kubernetes, in particular, is a new tool, and there are not that many books dealing with it from a “start to finish” approach, looking at the whole software lifecycle, not only under a “I want to learn this piece of tech in isolation”.
Writing it also took a lot of time that I could be using in writing in this blog, I guess. Writing a book is a lot of hard work, but I’m proud of the result. I’m very excited to have it finally released!
