Hi,

I'm running an Elastic cluster on my internal network.  
Now I would like to spin up some dockers when load gets heavy.  
When I try to spin these up I can't seem to get them into the existing cluster.  
I always get a "failed to send join request to the master"

This is the compose file I use

```
> version: '2.2'
> services:
> elasticsearch:
> image: docker.elastic.co/elasticsearch/elasticsearch:6.5.4
> container_name: elasticsearch
> environment:
> - cluster.name=DMS
> - bootstrap.memory_lock=true
> - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
> - "discovery.zen.ping.unicast.hosts=10.3.1.202"
>       
> ulimits:
> memlock:
> soft: -1
> hard: -1
> volumes:
> - esdata1:/usr/share/elasticsearch/data
> ports:
> - 10.3.1.201:9201:9200
> - 10.3.1.201:9301:9300
> network_mode: bridge
> 
> volumes:
> esdata1:
> driver: local

> networks:
> esnet:

```

And this is the logging I get. 502-0 Is the name of an other node in my network.
