Health check
Health check filter architecture overview
This filter should be configured with the type URL
type.googleapis.com/envoy.extensions.filters.http.health_check.v3.HealthCheck
.
Note
Note that the filter will automatically fail health checks and set the x-envoy-immediate-health-check-fail header on all responses (both health check and normal requests) if the /healthcheck/fail admin endpoint has been called. (The /healthcheck/ok admin endpoint reverses this behavior).
