Overview of this book

Spring is a powerful and widely adopted framework for building scalable and reliable web applications in Java, complemented by Spring Boot, a popular extension to the framework that simplifies the setup and configuration of Spring-based applications. This book is an in-depth guide to harnessing Spring 6 and Spring Boot 3 for web development, offering practical knowledge of building modern robust web APIs and services. The book covers a wide range of topics that are essential for API development, including RESTful web service fundamentals, Spring concepts, and API specifications. It also explores asynchronous API design, security, designing user interfaces, testing APIs, and the deployment of web services. In addition to its comprehensive coverage, this book offers a highly contextual real-world sample app that you can use as a reference for building different types of APIs for real-world applications. This sample app will lead you through the entire API development cycle, encompassing design and specification, implementation, testing, and deployment. By the end of this book, you’ll have learned how to design, develop, test, and deploy scalable and maintainable modern APIs using Spring 6 and Spring Boot 3, along with best practices for bolstering the security and reliability of your applications and improving your application's overall functionality.

Deploying an application in Kubernetes

Docker containers are run in isolation. You need a platform that can execute multiple Docker containers and manage or scale them. Docker Compose does this for us. However, this is where Kubernetes helps. It not only manages the container but also helps you scale the deployed containers dynamically.

You will use Minikube to run Kubernetes locally. You can use it on Linux, macOS, and Windows. It runs a single-node Kubernetes cluster, which is used for learning or development purposes. You can install it by referring to the respective guide (https://minikube.sigs.k8s.io/docs/start/).

Once Minikube is installed, you need to update Minikube’s local insecure registry because, by default, Minikube’s registry uses Docker Hub. Adding an image to Docker Hub and then fetching it for local usage is cumbersome for development. You can add a local insecure registry to your Minikube environment by adding your host IP and local Docker registry...
