Health Checks
Summary
When defined, Health Checks will issue periodic health check requests to upstream servers and unhealthy upstream servers won't serve traffic.
See Envoy's outlier_detection for automatic upstream server health detection. In the presence of multiple upstream servers, it is recommended to set up either health_checks, outlier_detection, or both.
See the Envoy documentation for a list of supported parameters.
How to configure
Only one of http_health_check, tcp_health_check, or grpc_health_check may be configured per health_check object definition.
See Load Balancing for example configurations.
