This example brings up a cluster comprising three Elasticsearch nodes, using three docker-compose for each node.

1. Docker-Compose.version = v1.24.0
2. Docker for Linux.version = v18.09.6
3. Elasticsearch.version = v6.4.1
4. The following ports must be free on the host: 9200,9300

• Set the vm.max_map_count kernel to at least 262144

sysctl -w vm.max_map_count=262144

• Ensuring the network publish host is configured in docker-compose for each node

network.publish_host=es1.uggla.fr

• Starts the containers

docker-compose up

• Inspect status of cluster

curl http://127.0.0.1:9200/_cat/health
