MongoDB-Docker - 如何将项目插入 mongo-express

Question

我正在尝试使用

mongo

和

mongo-express

进行简单的 docker-compose，并尝试使用 Python 脚本插入文档。该项目已成功添加到

mongodb

，但未在

mongo-express

中显示。请帮助我。

compose.yaml

version: '3.0'
services: 
  mongodb:
    image: mongo
    container_name: mongodb
    ports:
      - "27017:27017"

  mongo-express:
    image: mongo-express
    environment:
      - ME_CONFIG_MONGODB_SERVER=mongodb
      - ME_CONFIG_MONGODB_PORT=27017
    container_name: mongo-express
    ports: 
      - "8080:8081"

测试.py

from pymongo import MongoClient

# Connect to MongoDB
client = MongoClient('mongodb://localhost:27017')

# Connect to database
db = client['testing']

# Connect to collection
collection = db['testcollection']

# Insert document
try:
    collection.insert_one({"name": "John Doe", "age": 100})
    print("test complete")
except:
    print("there was an error")
else:
    print("Finished")

我对此失去了理智。

您可以进入 MongoDB 容器并使用 MongoDB shell 检查数据是否位于正确的数据库和集合中：

docker exec -it mongodb mongo
use testing
db.testcollection.find().pretty()

这将向您显示测试集合中的文档。
