無法使用 docker 創建 mongo 數據庫

Question

我在使用 docker-compose 命令創建 mongo 數據庫時遇到問題。 Docker 桌面告訴我一切都已啟動並正在運行，包括數據庫，但我得到的只是標准的“管理員、配置、本地”而不是我想要創建的數據庫。 這是我的 docker-compose.yaml

version: '3'

services:

  app:
    build: ./
    entrypoint: ./.docker/entrypoint.sh
    ports:
    - 3000:3000
    volumes:
    - .:/home/node/app
    depends_on:
    - db

  db:
    image: mongo:4.4.4
    restart: always
    volumes:
      - ./.docker/dbdata:/data/db
      - ./.docker/mongo:/docker-entrypoint-initdb.d
    environment:
      - MONGO_INITDB_ROOT_USERNAME=root
      - MONGO_INITDB_ROOT_PASSWORD=root
      - MONGO_INITDB_DATABASE=nest
  
  mongo-express:
    image: mongo-express
    restart: always
    ports:
      - 8081:8081
    environment:
      - ME_CONFIG_MONGODB_SERVER=db
      - ME_CONFIG_MONGODB_AUTH_USERNAME=root
      - ME_CONFIG_MONGODB_AUTH_PASSWORD=root
      - ME_CONFIG_MONGODB_ADMINUSERNAME=root
      - ME_CONFIG_MONGODB_ADMINPASSWORD=root
    depends_on:
    - db

我在 .docker/mongo 中的 init.js

db.routes.insertMany([
  {
    _id: "1",
    title: "Primeiro",
    startPosition: {lat: -15.82594, lng: -47.92923},
    endPosition: {lat: -15.82942, lng: -47.92765},
  },
  {
    _id: "2",
    title: "Segundo",
    startPosition: {lat: -15.82449, lng: -47.92756},
    endPosition: {lat: -15.82776, lng: -47.92621},
  },
  {
    _id: "3",
    title: "Terceiro",
    startPosition: {lat: -15.82331, lng: -47.92588},
    endPosition: {lat: -15.82758, lng: -47.92532},
  }
]);

和我的 dockerfile

FROM node:14.18.1-alpine

RUN apk add --no-cache bash

RUN npm install -g @nestjs/cli

USER node

WORKDIR /home/node/app

這是我在使用 mongodb、nest app 和 mongo express 運行嵌套容器時從 docker 得到的“錯誤”日志（實際上還有很多，但由於某種原因一直認為它是垃圾郵件。

about to fork child process, waiting until server is ready for connections.

"user" : "root",

"roles" : [

{

"role" : "root",

"db" : "admin"

}

]

}

這就是運行 docker-compose ps 顯示的內容

這是我的 docker 桌面顯示的

MongoDB 容器僅在不存在數據庫時才創建數據庫。 您可能已經有了一個，這就是為什么沒有創建新數據庫並且沒有運行初始化腳本的原因。

刪除主機上./.docker/dbdata的內容。 然后使用 docker-compose 啟動容器，Mongo 應該會為您創建數據庫。
