Book Description

Move your Spring Boot application beyond “it works on my machine” and into a secure, repeatable, production-ready environment.

Building a successful Spring Boot application is only the beginning. It must also be packaged correctly, configured securely, deployed consistently, monitored continuously, and recoverable when something goes wrong.

Deploying Spring Boot Applications provides a practical, end-to-end guide to turning a tested Java application into a reliable production service. Using the connected Spring Store project, you will follow the complete release journey—from reproducible Maven builds and executable JARs to secure container images, automated CI/CD pipelines, cloud platforms, Kubernetes, observability, and disaster recovery.

Rather than presenting one hosting platform as the answer to every project, this book explains when to use a Linux server, a managed container platform, or Kubernetes—and what operational responsibilities remain with your team in each environment.

Inside, you will learn how to:

• Prepare Spring Boot applications for real production environments
• Manage profiles, external configuration, credentials, and JWT signing keys
• Run safe PostgreSQL migrations with Flyway
• Build traceable executable JARs and layered archives
• Use AOT processing, CDS, CRaC, and GraalVM native images appropriately
• Create secure multi-stage Docker images and Cloud Native Buildpack images
• Generate SBOMs, checksums, signatures, and build provenance
• Build CI/CD pipelines with GitHub Actions, protected environments, and OIDC
• Perform rolling, blue-green, and canary releases
• Verify deployments and recover through rollback or roll-forward strategies
• Run Spring Boot through Linux, systemd, Nginx, domains, and TLS
• Deploy containers with managed PostgreSQL and private cloud networking
• Configure Kubernetes Deployments, Services, Ingress, ConfigMaps, and Secrets
• Add startup, readiness, and liveness probes with graceful shutdown
• Set resource requests, limits, and Horizontal Pod Autoscaling
• Manage environments with Kustomize and understand where Helm fits
• Monitor applications with Actuator, Micrometer, Prometheus, and OpenTelemetry
• Design dashboards, actionable alerts, and service-level objectives
• Harden production workloads through least privilege and secure patching
• Build incident-response, backup, restore, and disaster-recovery procedures

This book emphasizes a critical production principle: a successful build does not prove that an application is ready, and a successful deployment does not prove that users can complete important operations.

By the final chapter, you will understand how source control, automated testing, Maven, Docker, CI/CD, PostgreSQL, Flyway, cloud infrastructure, Kubernetes, logs, metrics, traces, alerts, backups, and recovery work together as one dependable release system.

Ideal for Spring Boot developers, Java backend engineers, DevOps learners, and technical teams ready to move from application development into professional production operations.

Build once. Deploy consistently. Observe continuously. Recover confidently.
