Hi,

Trying to setup two ES clusters: "cluster1" & "cluster2" (each cluster has one node), but both dockers crash after few seconds

The first cluster:

docker-compose.yml:

```auto
version: '3.3'

services:

  elasticsearch1:
    hostname: elasticsearch1
    build:
      context: elasticsearch/
      args:
        ELK_VERSION: 6.7.0
    volumes:
      - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro
    ports:
      - "9201:9200"
      - "9301:9300"
    environment:
      - "ES_JAVA_OPTS=-Xmx500m -Xms500m"
    networks:
      - kibana-es

  kibana1:
    hostname: kibana1
    build:
      context: kibana/
      args:
          ELK_VERSION: 6.7.0
    volumes:
      - ./kibana/config/:/usr/share/kibana/config:ro
    ports:
      - "5601:5601"
    networks:
      - kibana-es

networks:
  kibana-es:
    driver: bridge

```

elasticsearch1.yml:

```auto
cluster.name: "cluster1"
network.host: 0.0.0.0

cluster:
  remote:
    cluster2:
      seeds: 192.168.56.1:9302
      skip_unavailable: false

```

The second cluster

docker-compose.yml:

```auto
version: '3.3'

services:

  elasticsearch2:
    hostname: elasticsearch2
    build:
      context: elasticsearch/
      args:
        ELK_VERSION: 6.7.0
    volumes:
      - ./elasticsearch/config/elasticsearch.yml:/usr/share/elasticsearch/config/elasticsearch.yml:ro
    ports:
      - "9202:9200"
      - "9302:9300"
    environment:
      - "ES_JAVA_OPTS=-Xmx500m -Xms500m"
    networks:
      - kibana-es2

  kibana2:
    hostname: kibana2
    build:
      context: kibana/
      args:
          ELK_VERSION: 6.7.0
    volumes:
      - ./kibana/config/:/usr/share/kibana/config:ro
    ports:
      - "5602:5601"
    networks:
      - kibana-es2

networks:
  kibana-es2:
    driver: bridge

```

elasticsearch2.yml:

```auto
cluster.name: "cluster2"
network.host: 0.0.0.0

cluster:
  remote:
    cluster1:
      seeds: 192.168.56.1:9301
      skip_unavailable: false

```

The log output for elasticsearch1

```

The connectivity is allowed between the two nodes.

Any idea if the problem is the configuration of my two clusters?

Hi @haux,

there are two immediate things that stand out:

> fetching nodes from external cluster [apache2] failed

and

> [192.168.56.1:9202]

`apache2` is not the one defined in the .yml file. And the port in use is 9202, should probably have been 9302.

A guess is that this definition is stored in the cluster settings on cluster1, see: [Remote clusters | Elasticsearch Guide [8.11] | Elastic](https://www.elastic.co/guide/en/elasticsearch/reference/current/modules-remote-clusters.html#configuring-remote-clusters) for more info.
