Provide option to stop Liberty server when application fails to start

For Digital Commerce, we are dockerizing all applications. Application life cycle ties to docker container life cycle. When the application fails to start, the container should also fail, so the orchestrator can notice the failure, then a new container will be deployed.

Currently, Liberty doesn't have an option to stop the server when there is an application failure during server start up. When there is an application failure during start up, the server continues to start, so the docker container is still running, orchestrator will not notice any issue because the container is still alive.

With this new feature, if there is an application failure during start up, Liberty server is stopped and then docker container will stop, The orchestrator notices this failure and will deploy a new container, this will avoid application downtime and improve the reliability and performance.

I opened PMR 21917,442,000 and tried to use the "set startTimeout" parameter, but it doesn't work. The response from WAS team is that "Liberty is not designed to stop a server when an application can't be started."

    Thank you for this suggestion. We believe the recommended approach to addressing this requirement is to create readiness probe implementations and hook those to Kubernetes Readiness. The MicroProfile Health APIs make it easy to write Kubernetes probes. If you have any concerns about this suggestion/resolution, please contact Graham Charters <charters@uk.ibm.com>.
