advancedContainerization with Docker
Why does a Dockerized Kafka consumer service need explicit health checks defined in its Dockerfile/Compose config?
Without one, Docker/Kubernetes only knows if the PROCESS is running, not whether it's actually able to connect to Kafka or process messages — a health check endpoint (backed by Actuator) that verifies real broker connectivity lets the orchestrator detect and restart a container that's alive but functionally stuck.
