* Elasticsearch cluster. In the Elasticsearch Dockerfile we can visualize variables to configure an Elasticsearch Cluster. These variables are used in the file *config_cluster.sh* to set them in the *elasticsearch.yml* configuration file. You can see the meaning of the node variables [here](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-node.html) and other cluster settings [here](https://github.com/elastic/elasticsearch/blob/master/distribution/src/config/elasticsearch.yml).
