Question

我已经运行了3个docker容器。 app，mongodb和elasticsearch。

当我从app连接到mongodb时，它看起来像这样：

mongoose.connect('mongodb://<name_of_the_container>/<database_name>');

当我尝试从app连接到elasticsearch时，它不起作用：

const esOptions = {
    log: 'error'
};
esOptions.host = '3dominatores:9200';
const esClient = new elasticsearch.Client(esOptions);

它在连接时不会出现任何错误，但在我尝试访问elasticsearch时会大声喊叫：Error: No Living connections。

我的docker-compose.yml看起来像这样：

version: "2"
services:
  3dominator:
    build: .
    image: 3dominator:0.1
    container_name: 3dominator
    environment:
      NODE_ENV: development
      DB_ENV: container
        ports:
          - "3004:3004"
    volumes:
      - ./src:/app/src
    links:
      - 3dominatordb
      - 3dominatores
  3dominatordb:
    image: mongo:3.4.1
    volumes:
      - ./data/mongodb/db:/data/db
    ports:
      - "27017:27017"
    container_name: 3dominatordb
 3dominatores:
    image: elasticsearch:latest
    ports:
      - "9200:9200"
      - "9300:9300"
    environment:
      ES_JAVA_OPTS: "-Xmx256m -Xms256m"
    networks:
      - elk
    container_name: 3dominatores
    links:
      - 3dominatordb
networks:
  elk:
    driver: bridge
