Explains Kubernetes StatefulSets using Postgres and Spring Boot

Original Description

Repo - https://github.com/therealdumbprogrammer/spring-k8s-workshop/tree/feature/video-7-db Docs - https://kubernetes.io/docs/concepts/workloads/controllers/statefulset/ In this video, we explore why databases are different from stateless applications in Kubernetes and when StatefulSets become necessary. Starting with Persistent Volumes (PV) and Persistent Volume Claims (PVC), we build up to running PostgreSQL with persistent storage, examine when a simple Deployment + Service + PVC is sufficient, and uncover the identity challenges that arise in replicated database systems. ⏱️ Timestamps 00:00 – Intro 01:08 – StatefulSets explained 11:07 – Deploying Postgres on k8s 21:34 – Adding DB support in code #SpringBoot #Kubernetes #SpringBootDocker #SpringBootOnKubernetes #KubernetesLocalSetup #SpringBootBuildImage #JavaDevelopers #SpringBootTutorial #KubernetesForJava #CloudNative #javamicroservices
