Docker通过网络组合连接容器

标签： docker curl elasticsearch networking docker-compose

我正在尝试使用elasticsearch设置docker compose，并能够通过共享网桥将其他容器连接到它。我可以设置两个容器，但是当我试图将它们连接在一起时，我得到“连接被拒绝”。

如果可能的话，我想使用expose代替ports documented here和discussed here，因为我认为这是当前版本的首选方法。我不知道如何设置它。

version: '2' # docker-compose config file format version

services:

  elasticsearch:
    image: docker.elastic.co/elasticsearch/elasticsearch:6.1.2
    container_name: elasticsearch
    environment:
      - cluster.name=docker-cluster
      - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
      - "discovery.zen.ping.unicast.hosts=elasticsearch"
    expose:
      - "9200"
      - "9300"
    volumes:
      - esdata:/usr/share/elasticsearch/data
    networks:
      esnet:


volumes:
  esdata:


networks:
  esnet:
    driver: bridge

似乎工作：

$ docker-compose -f docker-compose3.yml  up

但在另一个终端窗口中运行：

答案 0 :(得分：0)

你可以试试这样的东西吗？

版本：

服务：

elasticsearch:
  image: docker.elastic.co/elasticsearch/elasticsearch:6.1.2
  container_name: elasticsearch
  environment:
    - cluster.name=docker-cluster
    - "ES_JAVA_OPTS=-Xms512m -Xmx512m"
    - "discovery.zen.ping.unicast.hosts=elasticsearch"
  ports:
    - "9200"
    - "9300"
  volumes:
    - esdata:/usr/share/elasticsearch/data

卷：     esdata：

编辑：

确保dockerfile中有这样的行：

EXPOSE 9200 9300
