Developing with Spring Boot on Kubernetes

Learn to develop and deploy Spring Boot applications on Kubernetes through hands-on practice with containerization, orchestration, and microservices architecture. Set up your development environment with Docker and Kubernetes, then master creating Docker images for Spring Boot applications using both manual Dockerfile creation and Maven plugins with layered image optimization. Explore essential Kubernetes concepts including deployments, services, port forwarding, environment variables, and health checks through readiness and liveness probes. Build and deploy a complete microservices ecosystem featuring inventory, beer, and beer order services with supporting infrastructure including MySQL databases and JMS messaging. Implement advanced Kubernetes features such as ingress controllers, Spring Cloud Gateway for API routing, and graceful shutdown procedures. Configure consolidated logging solutions using the ELK stack (Elasticsearch, Logback, Kibana) with Filebeat for centralized log management across your microservices deployment.
