Hello everyone,

I am trying to configure elasticsearch cluster on docker with 3 different hosts which are identical. Any one of these should be master/data nodes. I have the following docker-compose.yml file. I am getting error master node not found and bootstrap cluster discovery shows empty. Can some one please check and see where I am doing wrong? I have tried replacing host1,host2, host3 with IP and FQDN with no luck. I can reach host1, host2, host3 external to docker container.

## docker-compose.yml:

version: '2.2'  
services:  
es01:  
image: [docker.elastic.co/elasticsearch/elasticsearch:7.1.1](http://docker.elastic.co/elasticsearch/elasticsearch:7.1.1)  
container\_name: es01  
environment:  
- node.name=host1  
- node.data=true  
- discovery.seed\_hosts=host1,host2,host3  
- cluster.initial\_master\_nodes=host1,host2,host3  
- cluster.name=ELK\_Prod  
- node.master=true  
- bootstrap.memory\_lock=true  
- "ES\_JAVA\_OPTS=-Xms1024m -Xmx1024m"  
- Des.discovery.zen.ping.unicast.hosts=host1,host2,host3  
- Des.discovery.zen.minimum\_master\_nodes=1  
- Des.network.publish\_host=host1  
- transport.tcp.port=9300  
- http.port=9200  
ulimits:

Hi @nila

I assume you are trying to do it with Docker-Compose, correct? What I would do is the following:  
Make a service for each host you want to run as part of the ELK-Stack. You can use the configuration file (docker-compose.yml) provided in [this](https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html#docker-cli-run) guide.

Hope this helps.
