Trying to make it clustering with docker compose.  
I have two elasticsearch docker containers which are deployed in different Docker Hosts.

**docker-compose.yml for docker-container-1**

> ```
> services:
> elasticsearch:
> restart: always
> hostname: elasticsearch
> image: docker-elk/elasticsearch:1.0.0
> build:
> context: elasticsearch
> dockerfile: Dockerfile
> environment:
> discovery.type: zen
> ports:
> - 9200:9200
> - 9300:9300
> env_file:
> - ./elasticsearch/elasticsearch.env
> volumes:
> - elasticsearch_data:/usr/share/elasticsearch/data
> 
> ```

**docker-compose.yml for docker-container-2**

> ```
> services:
> elasticsearch:

**elasticsearch.yml on the elasticsearch-docker-container-1 on the Docker-Host 1**

> xpack.security.enabled: true  
> cluster.name: es-cluster  
> node.name: es1  
> network.host: 0.0.0.0  
> node.master: true  
> node.data: true  
> transport.tcp.port: 9300  
> path.data: /usr/share/elasticsearch/data  
> path.logs: /usr/share/elasticsearch/logs  
> discovery.zen.minimum\_master\_nodes: 1  
> gateway.recover\_after\_nodes: 1  
> discovery.zen.ping.unicast.hosts: ["host1:9300", "host2:9300","host1:9200", "host2:9200"]  
> network.publish\_host: host1

**elasticsearch.yml on the elasticsearch-docker-container-2 on the Docker-Host 2**

> ```
> xpack.security.enabled: true
> cluster.name: es-cluster
> node.name: es2
> network.host: 0.0.0.0
> node.master: true
> node.data: true
> transport.tcp.port: 9300
> path.data: /usr/share/elasticsearch/data
> path.logs: /usr/share/elasticsearch/logs
> discovery.zen.minimum_master_nodes: 1
> gateway.recover_after_nodes: 1

> network.publish_host: host2
> 
> ```

**Below is the result of GET /\_cluster/health?pretty and it shows that there is only one node.**

According to the document below at least three elasticsearch nodes are required.

Each elasticsearch container should be at different Docker host?

Thank you.
