We set-up the kubernetes cluster with 3 nodes. One as master and two are slaves. And installed zookeeper and active mq in the master node. When we see the logs after deploying our application it showing http://foo.bar.com:2181(active(http://foo.bar.com:2181(active) mq DNS name) can't access or reach. If we change that activemq domain name to IP address in a properties file, it works fine.

I think name resolution is not happening in kubernetes, can you help how can i get this work automatically? because i cant change the property file always when there is new deployment.
