Health Check

The health check will answer with status 200 OK on every port with the configured health_path setting or the COUPER_HEALTH_PATH environment variable.

As soon as the gateway instance receives a SIGINT or SIGTERM the check will return a status 500 Internal Server Error.

A shutdown delay (environment variable COUPER_TIMING_SHUTDOWN_DELAY) allows the server to finish all running requests and gives a load balancer time to pick another gateway instance. After this delay the server goes into shutdown mode and no new requests will be accepted.

The shutdown timings (COUPER_TIMING_SHUTDOWN_TIMEOUT) default to 0 which means no delaying with development setups.
