Safely Deploying a 100K line Envoy YAML Configuration to Production

summary
Lyft describes deploying a single Envoy config repo that grows to 100K lines and builds three concrete safeguards: automated scripts that prune dead routes and clusters, running Envoy in validation server mode plus the open source config_load_check to reject bad bootstrap YAML, and a unit-test harness called the router check tool that auto-generates and enforces routing tests and coverage. These tools catch first-match routing regressions, deprecated fields, and runtime-driven behavior so deploys are safe and self-service.
