This document discusses how Spring Boot applications can be optimized to run well on Kubernetes. It describes building a Docker image for a Spring Boot application using multi-stage builds and custom layers to create a slim image. It then covers configuring health checks, graceful shutdown, and other features to prepare the application for deployment on Kubernetes. The document suggests using the spring-boot-maven-plugin to build images and provides an overview of the journey to production for Spring Boot applications on Kubernetes.
