Dockerfile 运行错误。总是出现错误“拓扑已关闭”

Question

我有一个关于“拓扑已关闭”的错误，无法连接到 mongodb，并且还出现此错误 MongooseServerSelectionError。请检查下面的错误日志。

我尝试了许多来自其他来源的配置，但没有成功。希望有人已经知道/能够解决这个问题。

Error: MongooseServerSelectionError: connect ECONNREFUSED 0.0.0.0:27017/home/app/node_modules/mongodb/lib/sdam/topology.js:225
    drainWaitQueue(this[kWaitQueue], new error_1.MongoTopologyClosedError());

}

Node.js v19.9.0

我在这些链接上尝试了很多配置，但没有成功。

使用 Docker 运行 MongoDB“首次连接时无法连接到服务器 [localhost:27017]”

MongoError：连接ECONNREFUSED 127.0.0.1:27017

我的dockerfile

FROM node:19-alpine
ENV MONGO_DB_USERNAME=admin \
    MONGO_DB_PWD=password

RUN mkdir -p /home/app

COPY . /home/app
WORKDIR /home/app

RUN npm install
RUN npm run build
CMD ["node", "./dist/index.js"]

我的 mongodb 连接

import mongoose from "mongoose";
//localhost ~~ 127.0.0.1 ~~ 0.0.0.0 won't work
// tried this "mongodb" or "mongo-express" from docker-compose file still not working
export const mongooDbConnect = () => {
  mongoose
    .connect("mongodb://admin:[email protected]:27017", { 
      dbName: "car_be",
    })
    .then(() =>
      console.log(
        "****************\n\n Connected to the MONGODB database \n\n****************"
      )
    )
    .catch((err) => console.log(`Error: ${err}`));

  return mongoose;
};

我的 docker-compose 文件

version: "3"
services:
  mongodb:
    image: mongo
    ports:
      - 27017:27017
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=password
    volumes:
      - mongo-data:/data/db
  mongo-express:
    image: mongo-express
    restart: always 
    ports:
      - 8080:8081
    environment:
      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin
      - ME_CONFIG_MONGODB_ADMINPASSWORD=password
      - ME_CONFIG_MONGODB_SERVER=mongodb
volumes:
  mongo-data:
    driver: local

PS。我只能在本地运行完整的功能。只有 docker 镜像无法连接。

我刚刚通过将 0.0.0.0 / 127.0.0.1 / localhost 更改为 docker 主机给出的 IP 地址解决了这个问题。你可以从这里找到它
