Operate Kubernetes workloads: extend the platform with the operator pattern
summary
Kubernetes gets extended with an application-specific controller that watches a CustomResourceDefinition and creates the real pieces (StatefulSets, ConfigMaps, Secrets, PVCs, NetworkPolicies) to run Apache Kafka. The demo shows Strimzi on minikube bringing up 3 Zookeeper pods and 3 brokers, then performing a config change that triggers a rolling update and scaling from 3→5 brokers automatically. Operator SDKs exist for Go and Java and the Operator Lifecycle Manager handles install/upgrade of the operator itself.
