So we have a 3-node Elasticsearch cluster ready to handle more work.
## Access the service
*Don't forget* that services in Kubernetes are only acessible from containers in the cluster. For different behavior you should [configure the creation of an external load-balancer](http://kubernetes.io/v1.0/docs/user-guide/services.html#type-loadbalancer). While it's supported within this example service descriptor, its usage is out of scope of this document, for now.
