Istio Traffic Management

This tackles the gnarly parts of Istio traffic management with ready-to-use YAML templates for canary deployments, circuit breakers, and traffic mirroring. It covers the core resources you actually need (VirtualService, DestinationRule, Gateway) with practical examples like weighted routing, retry policies, and fault injection. The templates are production-ready and include the debugging commands that'll save you when traffic isn't flowing where you expect. Good for when you're past basic Istio setup and need to implement real traffic policies without piecing together scattered documentation.
