[jboss-jira] [JBoss JIRA] (JGRP-1840) Provide docker image for JGroups

[ https://issues.jboss.org/browse/JGRP-1840?page=com.atlassian.jira.plugin.... ] Arne Osthues commented on JGRP-1840: ------------------------------------ My experience with docker and jgroups so far. Running multiple containers on one host works well since all containers can connect to each other through their default interface. For discovery using a gossip router is one solution that works. If the containers run on different hosts it gets more complicated. By default each container can only be reached by its host and other containers. The general ideas to get it working are: * Add an extra software network layer to put the containers into the same network. There are several tools that try to support this approach. i.E. [weave|https://github.com/zettio/weave] , [pipework|https://github.com/jpetazzo/pipework] and [libswarm|https://github.com/docker/libswarm]. * Trying to put the load on jgroups. The different hosts can be treated like different networks separated by a firewall. Using a TUNNEL can be a solution. I haven't found the perfect way yet. I am still trying to avoid the need for the extra software network since this it makes it more complicated to automate starting containers with tools like vagrant or fig. -- This message was sent by Atlassian JIRA (v6.3.1#6329)
