Docker 无法从一个容器连接到另一个容器

我有3个docker集装箱。应用程序、mongodb和elasticsearch

当我从应用程序连接到mongodb时，它看起来如下所示：

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

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

它在连接时不会发出任何错误的叫声，但当我尝试访问elasticsearch时，它会大声喊叫：

错误：没有活的连接

我的docker-compose.yml如下所示：

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

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

PS:docker和elasticsearch

我在上面发现了这个错误：

BTW elasticsearch已经启动并运行，我可以卷曲它……我甚至可以做

curl-XPOST'http://localhost:9200/projects/project/58d3ed8059ff2d001e5ae4a2'-d“{\“field\”：\“value\”}”

并返回success
