Dynamically Testing Individual Microservice Releases In Production

on YouTube ↗35m

" summary

Claim: deploy candidate pods into production and run realistic end‑to‑end tests without exposing users by using Istio to route only test traffic via an override header; an operator that emits VS/DR auto‑generates the needed VirtualService and DestinationRule per service/version so configs don’t explode. Implementation uses Envoy/Istio, must regex‑match collapsed header values, requires namespace isolation and header trust, and pairs with Flagger for real rollouts. Prototype exists as CLI+operator; demo hits Docker Hub issues but v0.2 is reported working.
