关于 docker-compose up 时 docker 容器退出

Question

我正在尝试将 Elasticsearch 与 docker 一起使用。

您可以在此处查看指南 -> https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

下面是我的 docker-compose.yml

version: '2.2'
services:
  elasticsearch1:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.0
    container_name: elasticsearch1
    environment:
      - node.name=master-node
      - cluster.name=es-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es-data01:/usr/share/elasticsearch/data
    ports:
      - 127.0.0.1:9200:9200
      - 127.0.0.1:9300:9300
    networks:
      - elastic
    stdin_open: true
    tty: true

  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.0
    container_name: elasticsearch2
    environment:
      - node.name=data-node1
      - cluster.name=es-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch1"
    ports:
      - 127.0.0.1:9301:9300
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es-data02:/usr/share/elasticsearch/data
    networks:
      - elastic
    stdin_open: true
    tty: true

volumes:
  es-data01:
    driver: local
  es-data02:
    driver: local

networks:
  elastic:
   # driver: bridge

问题是

1. 我无法通过curl -XGET localhost:9200 连接
2. docker 容器在几秒钟后自动退出

你能帮帮我吗？

ps：当我尝试docker run 时，它可以工作。它们有什么区别？

docker run -d -p 9200:9200 -p 9300:9300 --name elasticsearch -it --rm -v els:/usr/share/elasticsearch/data -e "discovery.type=single-node" docker.elastic.co/elasticsearch/elasticsearch:7.7.0

Answer 1

请使用docker logs <your stopped container-id>查看容器日志，这里可以使用docker ps -a命令获取容器id。

也请关注this SO answer和set the memory requirements 这将帮助您在 docker 中运行 Elasticsearch。如果它没有帮助，请提供您可以如前所述获得的日志。

基于 cmets 添加更新的docker-compose

version: '2.2'
services:
  elasticsearch1:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.0
    container_name: elasticsearch1
    environment:
      - node.name=master-node
      - node.master=true
      - cluster.name=es-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "cluster.initial_master_nodes=master-node"
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es-data01:/usr/share/elasticsearch/data
    ports:
      - 127.0.0.1:9200:9200
      - 127.0.0.1:9300:9300
    networks:
      - elastic
    stdin_open: true
    tty: true

  elasticsearch2:
    image: docker.elastic.co/elasticsearch/elasticsearch:7.7.0
    container_name: elasticsearch2
    environment:
      - node.name=data-node1
      - node.master=false
      - cluster.name=es-cluster
      - bootstrap.memory_lock=true
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "cluster.initial_master_nodes=master-node"
    ports:
      - 127.0.0.1:9301:9300
    ulimits:
      memlock:
        soft: -1
        hard: -1
    volumes:
      - es-data02:/usr/share/elasticsearch/data
    networks:
      - elastic
    stdin_open: true
    tty: true

volumes:
  es-data01:
    driver: local
  es-data02:
    driver: local

networks:
  elastic:
   # driver: bridge

Answer 2

在您关注本文时，https://www.elastic.co/guide/en/elasticsearch/reference/current/docker.html

值得检查第二部分的限制和内存资源，因为 docker-compose 中的容器由于资源不足而退出。

Answer 3

Exited with code 137 错误是由于主机上的资源限制（通常是 RAM）。您可以通过将此行添加到 docker-compose 文件的环境变量来解决此问题：

- "ES_JAVA_OPTS=-Xms512m -Xmx512m"
