通过 docker 连接时 Mongodb 身份验证失败

Question

version: '3.8' 

services:
  mongodb:
    image: mongo
    container_name: mongodb-server
    environment:
      - MONGO_INITDB_ROOT_USERNAME=athul
      - MONGO_INITDB_ROOT_PASSWORD=athul
    volumes:
      - ~/mongo/data:/data/db
    networks:
      - backend-ecom
  
  backendapi:
    image: athulmekkoth/backend:v3
    container_name: backend-server 
    ports:
      - "5000:5000"  
    networks:
      - backend-ecom  
    env_file:
      - .env
    depends_on:
      - mongodb

networks:
  backend-ecom:
    driver: bridge

嘿，这一切都是我的 docker compose 文件，当我尝试连接到 Mongodb 时，我收到错误如下

MongoServerError: not authorized on test to execute command { find: "users", filter: { email: "[email protected]" }, projection: {}, limit: 1, singleBatch: true, batchSize: 1, lsid: { id: UUID("335d544a-5e1c-427e-b6ac-a961a3bf4726") }, $db: "test" }

我通过

连接到mongodb

const connect=()=>{
mongoose.connect(`mongodb://athul:athul@mongodb-server:27017/test`).then(() => {
    console.log("connected to db");
})
.catch((err) => {
    console.log("not connected to db", err);
});

}

请忽略我直接在连接字符串中使用密码和用户名的方式。任何帮助将不胜感激，谢谢

默认情况下，MongoDB root 用户只能访问管理数据库。因此，如果您需要访问测试数据库，您需要创建一个用户并授予测试数据库的权限。

所以：

1. 登录MongoDB

docker exec -it mongodb-server mongo -u athul -p athul --authenticationDatabase admin

2. 创建一个有权访问测试数据库的用户：

db = db.getSiblingDB("test");
db.createUser({
    user: "athul",
    pwd: "athul",
    roles: [{ role: "readWrite", db: "test" }]
});

3. 更新您的 docker-compose 文件（更改凭据并添加 init 脚本）
