Yep. I'm using containers and Kubernetes in production so I'm trying to stay far away from anything JVM-based. On top of being slow to start, memory hungry, and plagued by GC issues, JVM docker images are always huge. I don't want two layers of virtualization. If Docker and k8s become more mainstream that's probably bad news for a lot of JVM projects. Of course, Pulsar itself is quite old (2013?) so it was built well before any of the containerization stuff took off.
