Java and Kubernetes: Deploying and Orchestrating Enterprise Applications

Modern Java development is unthinkable without cloud technologies and containerization. The book "Java and Kubernetes" is a comprehensive guide that will take you from creating a simple monolithic application to a full-fledged microservice architecture running in a Kubernetes cluster.

The author, Alexey Petrov, a senior developer with 10 years of experience, shares proven practices and real-world cases. You will learn how to overcome typical problems when migrating to Kubernetes: configuration management, scaling, monitoring, and ensuring fault tolerance.

What you will learn from this book:

• How to containerize Java applications (Spring Boot, Jakarta EE, Micronaut) using Docker and optimize images for production.
• Kubernetes basics: Pods, Deployments, Services, ConfigMaps, Secrets — and their implementation in Java.
• Building microservices: from monolith decomposition to organizing Service Discovery and API Gateway.
• State management: working with databases in Kubernetes (StatefulSets, PersistentVolumeClaims).
• CI/CD for Java projects: automating build, testing, and deployment in Kubernetes with Jenkins and GitLab CI.
• Monitoring and logging: integration with Prometheus, Grafana, and the ELK stack for Java applications.
• Security: secret management, network policies, and container security (Pod Security Standards).
• Advanced scenarios: A/B testing, Canary releases, Autoscaling (HPA, VPA), and Service Mesh (Istio).

Who this book is for:

• Java developers who want to master modern deployment methods and transition to DevOps.
• DevOps engineers specializing in the Java stack and looking for practical examples.
• Architects designing scalable systems based on Java and Kubernetes.
• Students and beginners who want to acquire an in-demand profession.

The book contains over 50 practical examples, ready-made YAML manifests, and source code on GitHub. You will learn not just to run Java in Kubernetes, but to build reliable, scalable, and easily maintainable systems ready for high loads.

Whether you work with Spring Boot, Quarkus, or classic Java EE, this book will give you universal tools for successful work in a cloud environment.
