Welcome to your adventure into cloud-native application development! This blog will guide you through the essentials of how to effectively use the Cloud Native Spring in Action book, authored by Thomas Vitale. With the help of Spring Boot and Kubernetes, you’ll learn the ropes of building, containerizing, and deploying applications that live and thrive in the cloud.

Understanding the Structure of the Book

The book is designed to walk you through a series of chapters, each packed with both initial and final code versions. Think of it like a culinary recipe book; you can start with basic ingredients (initial code) and follow through to a delicious dish (final code). For example, consider Chapter 4; you can begin with Chapter0404-begin and after following the examples, check out Chapter0404-end for the finished product!

Setting Up Your Environment

Before diving into the code, ensure you have the following prerequisites installed:

• Java 17+ (OpenJDK: Eclipse Temurin)
• GraalVM: GraalVM
• JDK Management: SDKMAN
• Docker 26+ (Docker for Linux, Docker Desktop for Mac, Docker Desktop for Windows)
• Kubernetes 1.30+ (Install kubectl, and minikube)
• Other: HTTPie

Code Samples: Gradle vs. Maven

The book predominantly uses Gradle as the build tool. If you are more comfortable with Maven, don’t fret! Here’s a handy mapping table to help you transition:

Gradle          | Maven
----------------|-------------------------
gradlew clean   | mvnw clean
gradlew build   | mvnw install
gradlew test    | mvnw test
gradlew bootJar | mvnw spring-boot:repackage
gradlew bootRun  | mvnw spring-boot:run
gradlew bootBuildImage | mvnw spring-boot:build-image -DskipTests

Exploring the Code by Chapter

As you dive into each chapter, you will tackle various essential topics from cloud-native principles to security measures. Below is a chapter overview:

• Chapter 1: Introduction to cloud native
• Chapter 2: Cloud native patterns and technologies
• Chapter 3: Getting started with cloud native development
• Chapter 4: Externalized configuration management
• Chapter 5: Persisting and managing data in the cloud
• Chapter 6: Containerizing Spring Boot
• And many more!

Troubleshooting Tips

If you stumble upon any hurdles during this process, here are some troubleshooting tips:

• Double-check your software version compatibility; ensure you’re on Java 17 or higher and using Docker 26.
• If you run into build issues, verify your Gradle or Maven commands against the mapping table provided earlier.
• Check internet connectivity for tools like Kubernetes and Docker as they often need to pull images and packages from the web.
• Consult the dedicated forum for the book: Cloud Native Spring in Action Forum.
