🍃 Cloud Native Spring in Action

This repository contains the source code accompanying the book Cloud Native Spring in Action - With Spring Boot and Kubernetes written by Thomas Vitale and published by Manning Publications.

There is a folder for each chapter, for which both an initial and final versions are available. For example, for chapter 4, you can use Chapter04/04-begin as a starting point to follow along with the examples in the chapter and Chapter04/04-end to check the code as it looks like at the end.

The book uses Spring Boot 2.7.3. You can find the same examples upgraded to the latest 2.7.x and 3.x versions of Spring Boot in dedicated branches. Feel free to use Spring Boot 3 while reading the book. Only a few minor changes are necessary to the code samples and they are documented here.

Gradle	Maven
./gradlew clean	./mvnw clean
./gradlew build	./mvnw install
./gradlew test	./mvnw test
