Hello all. I'm just beginning with Docker Swarm and am wondering the following: I have an application (.war for Tomcat, based on Springframework) that has an embedded Artemis to allow communication between Web Socket handlers. The application is like a multi-user chat, and uses a Topic to send messages between the Web Socket instances. When distributed every instance of the application knows every other instance and they create a network of brokers that allows messages from one Web Socket on one node to successfully reach a different Web Socket on a different node. There is no broker discovery (network limitation: no broadcast/multicast).
How can I achieve the same in a Docker Swarm? Ideally pulling a new instance of the application/container would somehow enter the Broker Network and start exchanging messages with them.
