on YouTube ↗23m

" summary

Shows how to translate Envoy filter docs into Istio EnvoyFilter steps: choose workload selector and direction, match listener/HTTP location, pick EnvoyFilter patch operations (add/remove/merge/insert before/after), and supply the three required pieces: filter name, type URL, and values. Demo applies an HTTP filter to sidecar inbound on port 80, inserting an IP-tagging filter that sets header X-Envoy-IP-Tag = "hello Envoy", verifies via kubectl curl, and recommends testing in a local envoy image and searching GitHub for examples.
