Node.js 无法从主机访问replicaset mongodb（docker）

我的nodejs代码在我的主机（MACOS）上运行，它正试图连接到docker中运行的mongodb复制集

version: "3"

services:
  redis_master:
    image: redis:2.8
    volumes:
      - "/Users/hiteshbaldaniya/docker-redis/master:/data/"
    ports:
      - "6379:6379"
    networks:
      - database

  mongodb_primary:
    build:
      context: ./
      dockerfile: DockerfileDB
    command: mongod --replSet "hdbrs" --dbpath "/data/27017/" --port 27017
    ports:
      - "27017:27017"
    volumes:
      - "/Users/hiteshbaldaniya/docker-mongodb/:/data/"
    networks:
      - database

  mongodb_secondary1:
    build:
      context: ./
      dockerfile: DockerfileDB
    command: mongod --replSet "hdbrs" --dbpath "/data/27018/" --port 27018
    ports:
      - "27018:27018"
    volumes:
      - "/Users/hiteshbaldaniya/docker-mongodb/:/data/"
    networks:
      - database

  mongodb_secondary2:
    build:
      context: ./
      dockerfile: DockerfileDB
    command: mongod --replSet "hdbrs" --dbpath "/data/27019/" --port 27019
    ports:
      - "27019:27019"
    volumes:
      - "/Users/hiteshbaldaniya/docker-mongodb/:/data/"
    networks:
      - database

  hdb_nginx:
    build:
      context: ./nginx/
      dockerfile: DockerfileNginx.dev
    ports:
      - "8081:80"
    volumes:
      - "/Users/hiteshbaldaniya/logs/docker-nginx/:/var/log/nginx/"
    networks:
      - backend

networks:
  backend:
    driver: bridge
  database:
    driver: bridge

所有3个端口在我的主机上都是打开的，我尝试使用telnet，我也能够连接到所有端口

我的nodejs应用程序使用mongodb节点驱动程序并使用以下配置

module.exports = {
  servers: [{
      host: 'localhost',
      port: 27017,
    },
    {
      host: 'localhost',
      port: 27018,
    },
    {
      host: 'localhost',
      port: 27019,
    },
  ],
  database: 'mydatabase',
  options: {
    "raw": false,
    "poolSize": 5,
    "readPreference": "primaryPreferred",
    "w": 1,
    "wtimeout": 12000,
    "replicaSet": "hdbrs"
  }
};

当连接到mongodb时，我的应用程序抛出以下错误。这里有人能帮我吗

谢谢，

我找到了解决办法。通过在my/etc/hosts文件中添加主机条目

127.0.0.1 mongodb_primary
127.0.0.1 mongodb_secondary1
127.0.0.1 mongodb_secondary2

在从主机连接到docker内部运行的mongodb时，我仍然不确定localhost有什么问题，我仍然需要了解它的行为

仅针对节点，我还尝试在mongodb运行期间在命令行中添加--bind_ip_all

如果有人知道，一定要告诉我。谢谢
