I’ve read that the main benefit of docker swarm is high availability.
So I would like to use it for deploying wildfly instances containing my application.
However wildfly session replication requires that each instance runs with a unique node name e.g. passed on each node’s startup command:
-Djboss.node.name=node2 e.t.c. and that all nodes can initiate communication and advertise themselves to the load-balancer via a multicast addressing.
How can I provide the following two features using docker-swarm? e.g.
- Is there any unique name per swarm node which could be used for passing to wildfly?
- Is there a (free) way to support multicast addressing inside the swarm network?
