Health Checks

For health checks and readiness probes you can enable the inbuilt health check http server by setting the following environment variables (or corresponding CLI option) :

PUBSUB_HEALTH_SERVER=true

PUBSUB_SERVER_PORT=8080

This will expose a very simple http server that checks the static method isHealthy and returns status code accordingly.

You can also define your own server in your app and use the public static method directly as part of your custom health check endpoint.
