Java and Kubernetes: Microservice Development and Deployment

Modern Java development is unthinkable without containerization and orchestration. The book "Java and Kubernetes" is a practical guide that will take you from your first steps with Docker to full-fledged management of a microservice architecture in Kubernetes. It is designed for Java developers who want to master modern DevOps tools and stop fearing deployment.

What is this book about?

The book covers the full lifecycle of a Java application in a cloud environment:

• Containerization of Java applications — creating efficient Docker images for Spring Boot, Quarkus, and Micronaut, optimizing size and build time.
• Kubernetes basics — cluster architecture, pods, services, deployments, config maps, and secrets.
• Microservice architecture — designing and implementing microservices in Java, inter-service communication, service discovery.
• State management — working with databases, caches, and message queues in Kubernetes.
• Monitoring and logging — setting up Prometheus, Grafana, and the ELK stack for Java microservices.
• CI/CD — automating build, testing, and deployment using Jenkins and GitLab CI.
• Security — managing secrets, RBAC, pod security policies.

Who is this book for?

• Java developers who want to learn Kubernetes and containerization.
• DevOps engineers working with the Java stack.
• Team leads and architects planning a transition to microservices.
• Students and beginners looking to understand modern cloud development.

What will you learn?

• How to package a Java application into a Docker image and optimize it.
• How to set up a local Kubernetes cluster using Minikube or Kind.
• How to deploy a multi-component application with a database and a queue.
• How to implement Service Discovery and Load Balancing for microservices.
• How to configure automatic scaling and application updates.
• How to integrate Java applications with the Kubernetes API.

The book contains numerous practical examples, ready-to-use manifests, and code snippets. All examples are tested on current versions of Java 17+ and Kubernetes 1.27+. After reading it, you will be able to confidently design, develop, and maintain Java microservices in a production Kubernetes environment.

This is not just theory — it is a practical tool that will help you become a sought-after specialist in the field of cloud Java solutions.
