I tried to follow following blog entry but not sure it is still valid. http://blog.keycloak.org/2015/04/running-keycloak-cluster-with-docker.html

I was trying to follow this to run multiple docker containers in cluster with the latest images. But when I ran second keycloak container, I didn't see this container joining the 1st cluster. I was seeing this in the log for the second container.

[0m[0m12:31:56,385 INFO [org.infinispan.remoting.transport.jgroups.JGroupsTransport] (MSC service thread 1-2) ISPN000094: Received new cluster view for channel keycloak: [saskeycloak-fbtit|0] (1) [saskeycloak-fbtit] 

To get it working I had to update private interface in standalone-ha.xml to use docker container's IP. 

 

<interface name="private">

    <!--<inet-address value="${jboss.bind.address.private:127.0.0.1}"/>-->

    <inet-address value="172.17.0.3" />

</interface>

Is that really needed or do we have a better way to get it working?
