Unexpected application shutdown

Hi

I’m using Spring Boot 2.1.6 and Spring Cloud 2.1.2 and want to add Spring Cloud Zookeeper to my project for service discovery. However after successful start my application silently terminates (I assume it was shutdown somewhere inside the library). I don’t see any exceptions in the log or error messages.

I run Zookeeper: docker run --name zookeeper --restart always -d -p 2181:2181 zookeeper

I turned on debug mode in the logs:

You don’t have the web or webflux starter, so there’s nothing to keep boot running
