docker-compose 运行命令：无法成功工作 Windows 10

Question

When I run the command docker-compose up this keeps coming up and is stuck in an infinite loop of it. It starts both services but then it gets stuck at the message about es-03 which I have no idea why its doing that if I do not have it. Is there something causing this?

Inside of my docker-compose.yml file I have the following:

version: '2.2'
services:
  es01:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.12.1
    container_name: es01
    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.seed_hosts=es02,es03
      - cluster.initial_master_nodes=es01,es02,es03
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - data01:/usr/share/elasticsearch/data
    ports:
      - 9200:9200
    networks:
      - elastic

  kib01: 
    image: docker.elastic.co/kibana/kibana:7.12.1
    container_name: kib01
    ports:
      - 5601:5601
    environment:
      ELASTICSEARCH_URL: http://es01.9200
      ELASTICSEARCH_HOSTS: http://es01:9200
    networks:
      - elastic

volumes:
  data01:
    driver: local

networks:
   elastic:
     driver: bridge

Answer 1

You are trying to start a multi-node cluster, where es01 , es02 and es03 are the nodes, but your docker compose only have the configuration for one node, the es01 node.

These two lines tells your es01 node to look for the es02 and es03 nodes to form a cluster.

discovery.seed_hosts=es02,es03
cluster.initial_master_nodes=es01,es02,es03

If you just want a single-node cluster, you need to change your environment in your docker compose, try this.

    environment:
      - node.name=es01
      - cluster.name=es-docker-cluster
      - discovery.type=single-node
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
