K8s Operators: The next war
summary
Describes the fragmented Kubernetes operator ecosystem and shows concrete failure cases and fixes across technologies: RabbitMQ operator demos (replica mismatches and real cluster behavior), writing custom reconcile functions, rolling-upgrade rebalancing, PodAffinity and persistence issues, Istio sidecar readiness and networking quirks, Helm/Bitnami install pitfalls, and Nomad port-mapping and DNS traps. Presents deployment stats (25M weekly RabbitMQ downloads) and practical war stories about what was built, what broke, and what solutions actually worked.
