Answer
Readiness gates delay traffic until apps confirm external dependencies are healthy.
Quick Answer
External dependency readiness gates let you declare that a Pod isn't ready until an external condition is met — beyond just the Pod's own health check. For example, a Pod might be healthy internally but not ready until a sidecar (like a service mesh proxy) finishes initializing. Readiness gates add a programmatic external condition to the standard readiness probe.
