| # Elasticsearch for Kubernetes | ||||
| 
 | ||||
| Kubernetes makes it trivial for anyone to easily build and scale [Elasticsearch](http://www.elasticsearch.org/) clusters. Here, you'll find how to do so. | ||||
| Current Elasticsearch version is `1.7.1`. | ||||
| Current Elasticsearch version is `5.6.2`. | ||||
| 
 | ||||
| [A more robust example that follows Elasticsearch best-practices of separating nodes concern is also available](production_cluster/README.md). | ||||

This is meant to be for the sake of simplicity and [should be adapted according to your storage needs](../../docs/design/persistent-storage.md). | ||||

 | ||||
| ## 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. | ||||
