Istio Traffic Management

If you're running Istio in production and need to set up canary deployments, circuit breakers, or traffic mirroring without digging through docs every time, this gives you ready-to-use YAML templates and a solid mental model of how VirtualServices, DestinationRules, and Gateways actually work together. The templates cover the common scenarios like weighted routing, retries with backoff, and fault injection for chaos testing. It's thorough on the "how do I configure this" part and includes debugging commands using istioctl. One thing to note: it assumes you already have Istio installed and understand basic service mesh concepts. This is for operators who know what they want to do but need the exact syntax and best practices to do it safely.
