Java-based microservices, containers, Kubernetes - how to
summary
Builds a Spring Boot guestbook microservice, containerizes it with Maven/Docker plugins, and deploys a 3-node Kubernetes cluster running MySQL and Redis; demo shows Docker CPU quota capping a runaway Java process, Docker Compose for local stacks, scaling a replication controller from 2 to 4 replicas, and a successful canary and Kubernetes rolling update from v1 to v2 with an external load balancer. Concrete tools: Spring Boot, Docker/Spotify plugin, MySQL, Redis, Docker Compose, and Kubernetes; all demos run and are observable.
