Elasticsearch cluster in two different hosts with one node as Docker container and another as Service

Elastic Stack Elasticsearch
1

I have an existing Elasticsearch server in Ubuntu, for the purpose of better performance I want to add one more node in the Cluster. Can I do it with docker by not changing the existing system?
I have tried it with docker-compose file as follows:

##########################
version: '2.2'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:7.2.0
container_name: elasticsearch
environment:
- "cluster.name=elasticsearch"
- "node.name=slave-node1"
- "node.master=false"
- "node.data=true"
- "network.host=192.168.2.20"
- "Des.network.publish_host=192.168.2.20"
- "network.bind_host=192.168.2.20"
- "bootstrap.memory_lock=true"
- "http.cors.enabled=true"
- "http.cors.allow-origin=*"
- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
- "Des.discovery.zen.ping.unicast.hosts=192.168.2.10, 192.168.2.20"
- "cluster.initial_master_nodes=master-node"
- "Des.discovery.zen.minimum_master_nodes:2"
- "transport.tcp.port:9300"

networks:
  - esnet
ports:
  - '9200:9200'
  - '9300:9300'
ulimits:
  memlock:
    soft: -1
    hard: -1
volumes:
  - esdata:/var/lib/elasticsearch

volumes:
esdata:
driver: local

networks:
esnet:

But getting the error:

Did anyone try such scenario?
