Spring Boot Containerization: Docker Image Slimming from 800MB to 200MB & K8s Probe Tuning

This article details Spring Boot containerization best practices: multi-stage Dockerfiles with JRE-alpine and layered jars cut image size from 800MB to ~200MB; startup probes prevent slow-start mis-kills; readiness/liveness separation avoids DB-induced restart storms; rolling updates with maxUnavailable=0, preStop sleep, and terminationGracePeriod eliminate 502 errors; CPU limits omitted to prevent GC throttling.
