Dockerize application parts of an Axon application?

Currently our applications are using Axon/JGroups and work nicely together, We are looking for ways to deliver/scale our applications using Docker. I am wondering if someone has already implemented a way of delivering Axon enabled applications using Docker?
I made some Dockers tests with our applications, but they are unable to find each other thus are unsuccessful in joining a cluster.

Anyone a clue how this could be achieved?

I have been doing just that. We run a docker image with bridged networking on a vm and cluster using jgroups. The jgroups cluster is setup to use tcp for communication between nodes. However, because docker NATs the traffic out of the container you need to make sure jgroups uses the the external_addr property otherwise the internal IP address is used.
