我有一个使用Docker容器的项目：

1. API容器（NestJS）
   1.蒙戈集装箱
   NestJS不想连接到mongoDB，而是连接到mongoDB Atlas。什么都试过了，没有用（
   docker-compose.yml:

api:
    image: service-api
    build:
      context: "api/."
      dockerfile: "Dockerfile"
    environment:
      NODE_ENV: production
      ME_CONFIG_MONGODB_ADMINUSERNAME: root
      ME_CONFIG_MONGODB_ADMINPASSWORD: example
      ME_CONFIG_MONGODB_URL: mongodb://root:example@mongo:27017/eshop
    networks:
      - backend
      - frontend
    depends_on:
      - 'mongo'
      - 'rabbitmq'
    ports:
      - "8802:8802"
    deploy:
      placement:
        constraints: [ node.role == manager ]
      replicas: 1
...

  mongo:
    image: mongo:6.0.2
    networks:
      - backend
    ports:
      - "27017:27017"
    environment:
      MONGO_INITDB_DATABASE: eshop
      MONGO_INITDB_ROOT_USERNAME: root
      MONGO_INITDB_ROOT_PASSWORD: example
    volumes:
      - "/opt/mongo/data/db:/data/db"
    deploy:
      placement:
        constraints: [ node.role == manager ]
      replicas: 1

NestJS app.module.ts：

const MongoModule = MongooseModule.forRoot('mongodb://root:example@mongo:27017/eshop', {
  useNewUrlParser: true,
  useUnifiedTopology: true, 
  useFindAndModify: false,
});

Mongoose 版本：^5.8.11
错误信息：

[MongooseModule] Unable to connect to the database. Retrying (1)... +29999ms
[MongooseModule] Unable to connect to the database. Retrying (2)... +33002ms
...
[MongooseModule] Unable to connect to the database. Retrying (7)... +33002ms

所有东西都在同一个堆栈、同一个网络中工作，但仍然无法连接
