Hi, all.  
I tried to run Elasticsearch cluster with docker swarm.  
However, there is a problem described in [https://github.com/elastic/elasticsearch-docker/issues/91#issuecomment-319679786](https://github.com/elastic/elasticsearch-docker/issues/91#issuecomment-319679786).  
Solutions from above issue are:

- To specify the network interface. Set `network.host: _eth0_` instead of `network.host: 0.0.0.0` in elasticsearch.yml
- Or not to use VIP (Virtual IP) mode. Set `endpoint_mode: dnsrr` in docker-compose.yml

I want to know the reason why VIP is a problem.  
Why elasticsearch cluster doesn't work when advertising VIP endpoint?

My configuration is:  
elasticsearch-master.yml

```
network.host: 0.0.0.0
cluster.name: docker-test-cluster
node.master: true
node.data: false
node.ingest: false
discovery.zen.ping.unicast.hosts: ["elasticsearch-master"]

```

elasticsearch-data.yml

```
network.host: 0.0.0.0
cluster.name: docker-test-cluster
node.master: false
node.data: true
node.ingest: false
discovery.zen.ping.unicast.hosts: ["elasticsearch-master"]

```

elasticsearch-coordinating-only.yml

```
network.host: 0.0.0.0
cluster.name: docker-test-cluster
node.master: false
node.data: false
node.ingest: false
discovery.zen.ping.unicast.hosts: ["elasticsearch-master"]

```

docker-compose.yml is:

```
version: "3.3"
services:
  elasticsearch-master:
    hostname: elasticsearch-master
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.3
    configs:
    - source: elasticsearch-master.yml
      target: /usr/share/elasticsearch/config/elasticsearch.yml
      uid: '1000'
      gid: '1000'
      mode: 0444
    networks:
    - backend

  elasticsearch-data:
    hostname: elasticsearch-data
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.3
    configs:
    - source: elasticsearch-data.yml
      target: /usr/share/elasticsearch/config/elasticsearch.yml
      uid: '1000'
      gid: '1000'
      mode: 0440
    environment:
    - bootstrap.memory_lock=true
    - "ES_JAVA_OPTS=-Xms32g -Xmx32g"
    volumes:
    - /elasticsearch/data:/usr/share/elasticsearch/data
    networks:
    - backend

  elasticsearch-coordinating-only:
    hostname: elasticsearch-coordinating-only
    image: docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.3
    configs:
    - source: elasticsearch-coordinating-only.yml
      target: /usr/share/elasticsearch/config/elasticsearch.yml
      uid: '1000'
      gid: '1000'
      mode: 0440
    environment:
    - bootstrap.memory_lock=true
    - "ES_JAVA_OPTS=-Xms32g -Xmx32g"
    networks:
    - backend
    ports:
    - "9200:9200"
```
