无法使用 docker compose 运行 mongoexpress

Question

这是我关于 Node js 和 docker 的第一篇文章，所以请耐心等待。我正在使用 docker-compose 运行 mongo 和 mongo Express 容器，但 mongo Express 没有运行。当我在没有 docker-compose 的情况下运行 mongo 和 mongo Express 时，它工作得很好。所以，我认为我在 docker-compose 或 Node js 代码中遇到了一些问题

\n

docker-compose.yaml

\n

version: '3'\nservices:\n  mongodb:\n    image: mongo\n    ports:\n      - 27017:27017\n    environment:\n      - MONGO_INITDB_ROOT_USERNAME=admin\n      - MONGO_INITDB_ROOT_PASSWORD=password\n  mongo-express:\n    image: mongo-express\n    ports:\n      - 8080:8081\n    environment:\n      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin\n      - ME_CONFIG_MONGODB_ADMINPASSWORD=password\n      - ME_CONFIG_MONGODB_SERVER=mongodb\n

\n

服务器.js

\n

let express = require('express');\nlet path = require('path');\nlet fs = require('fs');\nlet MongoClient = require('mongodb').MongoClient;\nlet bodyParser = require('body-parser');\nlet app = express();\n\napp.use(bodyParser.urlencoded({\n  extended: true\n}));\napp.use(bodyParser.json());\n\napp.get('/', function (req, res) {\n    res.sendFile(path.join(__dirname, "index.html"));\n  });\n\napp.get('/profile-picture', function (req, res) {\n  let img = fs.readFileSync(path.join(__dirname, "images/profile-1.jpg"));\n  res.writeHead(200, {'Content-Type': 'image/jpg' });\n  res.end(img, 'binary');\n});\n\n// use when starting application locally\nlet mongoUrlLocal = "mongodb://admin:password@localhost:27017";\n\n// use when starting application as docker container\nlet mongoUrlDocker = "mongodb://admin:password@mongodb";\n\n// pass these options to mongo client connect request to avoid DeprecationWarning for current Server Discovery and Monitoring engine\nlet mongoClientOptions = { useNewUrlParser: true, useUnifiedTopology: true };\n\n// "user-account" in demo with docker. "my-db" in demo with docker-compose\nlet databaseName = "my-db";\n\napp.post('/update-profile', function (req, res) {\n  let userObj = req.body;\n\n  MongoClient.connect(mongoUrlLocal, mongoClientOptions, function (err, client) {\n    if (err) throw err;\n\n    let db = client.db(databaseName);\n    userObj['userid'] = 1;\n\n    let myquery = { userid: 1 };\n    let newvalues = { $set: userObj };\n\n    db.collection("users").updateOne(myquery, newvalues, {upsert: true}, function(err, res) {\n      if (err) throw err;\n      client.close();\n    });\n\n  });\n  // Send response\n  res.send(userObj);\n});\n\napp.get('/get-profile', function (req, res) {\n  let response = {};\n  // Connect to the db\n  MongoClient.connect(mongoUrlLocal, mongoClientOptions, function (err, client) {\n    if (err) throw err;\n\n    let db = client.db(databaseName);\n\n    let myquery = { userid: 1 };\n\n    db.collection("users").findOne(myquery, function (err, result) {\n      if (err) throw err;\n      response = result;\n      client.close();\n\n      // Send response\n      res.send(response ? response : {});\n    });\n  });\n});\n\napp.listen(3000, function () {\n  console.log("app listening on port 3000!");\n});\n

\n

如果我运行docker ps我只能看到 mongo 正在运行

\n

\n

当我使用以下命令运行 docker-compose 时，我会看到此日志，我怀疑存在问题。任何帮助表示赞赏

docker-compose -f docker-compose.yaml up
