I am using Docker Desktop with linux containers on Windows 10 and would like to launch the latest versions of the elasticsearch and kibana containers over a docker compose file.
Everything works fine when using some older version like 6.2.4.
This is the working docker-compose.yml file for 6.2.4.
version: '3.1'
services:
elasticsearch:
image: docker.elastic.co/elasticsearch/elasticsearch:6.2.4
container_name: elasticsearch
ports:
- "9200:9200"
volumes:
- elasticsearch-data:/usr/share/elasticsearch/data
networks:
- docker-network
kibana:
image: docker.elastic.co/kibana/kibana:6.2.4
container_name: kibana
ports:
- "5601:5601"
depends_on:
- elasticsearch
networks:
- docker-network
networks:
docker-network:
driver: bridge
volumes:
elasticsearch-data:
I deleted all installed docker containers and adapted the docker-compose.yml file by changing 6.2.4 to 7.0.1. By starting the new compose file everything looks fine, both the elasticsearch and kibana containers are started. But after a couple of seconds the elasticsearch container exits (the kibana container is running further). I restarted everything, attached a terminal to the elasticsearch container and saw the following error message:
...
ERROR: [1] bootstrap checks failed
[1]: the default discovery settings are unsuitable for production use; at least one of [discovery.seed_hosts, discovery.seed_providers, cluster.initial_master_nodes] must be configured
...
What must be changed in the docker-compose.yml file to get elasticsearch 7.0.1 working?
Making a few changes worked for me -
Add cluster.initial_master_nodes
to the elasticsearch service in compose -
environment:
- cluster.initial_master_nodes=elasticsearch
vm.max_map_count
on the linux box kernel setting needs to be set to at least 262144 -
$ sudo sysctl -w vm.max_map_count=262144
For development mode, you can use below settings as well -
environment:
- discovery.type=single-node
Working compose file for me -
version: '2.2'
services:
es01:
image: docker.elastic.co/elasticsearch/elasticsearch:7.0.1
container_name: es01
environment:
- cluster.initial_master_nodes=es01
ulimits:
memlock:
soft: -1
hard: -1
ports:
- 9200
For production mode, you must consider having multiple ES nodes/containers as suggested in the official documentation
