docker-compose.yml for elasticsearch and kibana

Question

My aim is to get the elasticsearch and kibana images from DockerHub working locally using Docker.

This does the trick and works perfectly...

docker network create mynetwork --driver=bridge

docker run -p 5601:5601 --name kibana -d --network mynetwork kibana 
docker run -p 9200:9200 -p 9300:9300 --name elasticsearch -d --network mynetwork elasticsearch

Today a bird whispered in my ear and said I should learn docker-compose. So I tried to do all of what's above inside a docker-compose.yml.

Here is my attempt.

version: "2.0"
services:
  elasticsearch:
    image: elasticsearch:latest
    ports:
      - "9200:9200"
      - "9300:9300"
    networks:
      - docker_elk
  kibana:
    image: kibana:latest
    ports:
      - "5601:5601"
    networks:
      - docker_elk
networks:
  docker_elk:
    driver: bridge

Unfortunately this does not work. I've been racking my brains as to why I always get the ECONNREFUSED error as shown below when i run docker-compse up.

$ docker-compose up

Answer 1

This works for me docker-compose.yml

    version: '3'
    services:
      elasticsearch:
        image: docker.elastic.co/elasticsearch/elasticsearch:7.6.2
        environment:
          - discovery.type=single-node
        ports:
          - 9200:9200
      kibana:
        image: docker.elastic.co/kibana/kibana:7.6.2
        ports:
          - 5601:5601

Answer 2

To add the hard dependency on elasticsearch for kibana, you need the depends_on variable to be set as shown below. Also, to add to @Phil McMillan's answer, you can set the elasticsearch_url variable in kibana, without static addressing using Docker's inbuilt DNS mechanism.

version: '2.1'
services:
     elasticsearch:
       image: docker.elastic.co/elasticsearch/elasticsearch:5.4.3
       container_name: elasticsearch
       networks:
           docker-elk:

     kibana:
       image: docker.elastic.co/kibana/kibana:5.4.3
       container_name: kibana
       environment:
          - "ELASTICSEARCH_URL=http://elasticsearch:9200"
       networks:
          - docker-elk
       depends_on:
          - elasticsearch

networks:
  docker-elk:
    driver: bridge

Note the environment variable ELASTICSEARCH_URL=http://elasticsearch:9200 just uses has the container name (elasticsearch) which the Docker DNS server is able to resolve.

Answer 3

You need to include the links.

version: "2.0"
services:
  elasticsearch:
    image: elasticsearch:latest
    ports:
      - "9200:9200"
      - "9300:9300"
    networks:
      - docker_elk
  kibana:
    image: kibana:latest
    ports:
      - "5601:5601"
    links:
      - elasticsearch
    networks:
      - docker_elk
networks:
  docker_elk:
    driver: bridge

UPDATED

When using the image elasticsearch:latest, it's Elasticsearch 5.0 and requires us to increase our Docker host virtual memory.

Before running the docker-compose, please make sure to run this command on your Docker host.

Linux:

su root
sysctl -w vm.max_map_count=262144

Windows (boot2docker)

docker-machine ssh default
sudo sysctl -w vm.max_map_count=262144

If you don't want to change your Docker host, just use the Elasticsearch 2.x image at elasticsearch:2
