Hm. I have had experience with running (embedded) Artemis (in Springframework) in a Docker Swarm. Most of what I had tried failed. The main reason was that the virtual network adapters that are available (sans any commercial and third-party ones) do not support broadcast/multicast so dynamic discovery fails. The ones that did support broadcast/multicast did not work properly when the swarm was distributed over multiple nodes.
I can not provide any code due to the commercial nature of the application. I can tell you how I solved it eventually: when running inside a docker swarm instance doing an 'nslookup tasks.service-name' (replace service-name with the actual service name) returns the IPs of all the (current) instances of the service. Using that information (and excluding the 127.*.*.*) I got the IPs of the other nodes in the service. With that information and using a dedicated ArtemisConfigurationCustomizer (from Springframework) I declared static connectors to all the other nodes, and built the cluster using static connectors only. Notice: I do not use XML configuration for Artemis, rather I use Springframework for configuration. Parse tcp://x.x.x.x:yyyy/ ...artemis.uri.ConnectorTransportConfigurationParser.newObject(URI, ?) Declare static connectors: ...artemis.core.config.Configuration.addConnectorConfiguration(String, TransportConfiguration) Declare static connectors as cluster backbone: ...artemis.core.config.ClusterConnectionConfiguration.setStaticConnectors(List<String>) Add the static cluster configuration: ...artemis.core.config.Configuration.addClusterConfiguration(ClusterConnectionConfiguration) That's admittedly a lot of work, in many places: docker for set-up, bash for lookup, Springframework for configuration, Artemis for configuration. I believe it *could* be done more concisely, but I did not see any interest in continuing that (and I still don't). 2017-09-28 11:27 GMT+03:00 Nick Stolwijk <nick.stolw...@gmail.com>: > Thanks. > I am looking now at Artemis and got it running through Rancher and Docker > Swarm. > > Has anyone got information about service discovery for Artemis with Docker > Swarm? > > Looking at the Kubernetes example I need to use some XSLT templates at > deployment to create the right override configuration.
