Zero-downtime deployment with Kubernetes, Spring Boot and Flyway
summary
Shows a concrete zero‑downtime path: Kubernetes rolling updates with specified maxUnavailable/maxSurge values, Spring Boot health endpoints for readiness, and Flyway file‑versioned migrations applied from DB migrations folder. Demo builds a Kotlin Spring Boot app with Jib, uses H2 locally, deploys a 3‑replica Deployment in a namespace, adds an addresses table and copies data in code (no triggers), upgrades to v2.x and rolls back to v2.1 while HTTP requests keep succeeding.
