Recover Kafka Replication and Consumption

Restore ISR health, right-size brokers, and prove produce/consume through a real Kafka protocol endpoint.

A advanced Linux challenge worth 20 points. Solve it hands-on in a real Linux environment in your browser - no local setup, no fake shells.

The Challenge

The orders topic has three partitions but only one in-sync broker, and the broker is OOMKilled. Scale to 3 replicas, set KAFKA_MIN_INSYNC_REPLICAS to 2, request 128Mi and limit 256Mi. Then open Kafka Console, publish an order, see it consumed, and run check.
