这是我在 node js 和 docker 中的第一篇文章，所以请多多包涵。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，它运行良好。所以，我认为我在 docker-compose 或节点 js 代码中遇到了一些问题

docker-compose.yaml

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

服务器.js

let express = require('express');
let path = require('path');
let fs = require('fs');
let MongoClient = require('mongodb').MongoClient;
let bodyParser = require('body-parser');
let app = express();

app.use(bodyParser.urlencoded({
  extended: true
}));
app.use(bodyParser.json());

app.get('/', function (req, res) {
    res.sendFile(path.join(__dirname, "index.html"));
  });

app.get('/profile-picture', function (req, res) {
  let img = fs.readFileSync(path.join(__dirname, "images/profile-1.jpg"));
  res.writeHead(200, {'Content-Type': 'image/jpg' });
  res.end(img, 'binary');
});

// use when starting application locally
let mongoUrlLocal = "mongodb://admin:password@localhost:27017";

// use when starting application as docker container
let mongoUrlDocker = "mongodb://admin:password@mongodb";

// pass these options to mongo client connect request to avoid DeprecationWarning for current Server Discovery and Monitoring engine
let mongoClientOptions = { useNewUrlParser: true, useUnifiedTopology: true };

// "user-account" in demo with docker. "my-db" in demo with docker-compose
let databaseName = "my-db";

app.post('/update-profile', function (req, res) {
  let userObj = req.body;

  MongoClient.connect(mongoUrlLocal, mongoClientOptions, function (err, client) {
    if (err) throw err;

    let db = client.db(databaseName);
    userObj['userid'] = 1;

    let myquery = { userid: 1 };
    let newvalues = { $set: userObj };

    db.collection("users").updateOne(myquery, newvalues, {upsert: true}, function(err, res) {
      if (err) throw err;
      client.close();
    });

  });
  // Send response
  res.send(userObj);
});

app.get('/get-profile', function (req, res) {
  let response = {};
  // Connect to the db
  MongoClient.connect(mongoUrlLocal, mongoClientOptions, function (err, client) {
    if (err) throw err;

    let db = client.db(databaseName);

    let myquery = { userid: 1 };

    db.collection("users").findOne(myquery, function (err, result) {
      if (err) throw err;
      response = result;
      client.close();

      // Send response
      res.send(response ? response : {});
    });
  });
});

app.listen(3000, function () {
  console.log("app listening on port 3000!");
});

如果我运行docker ps我只能看到 mongo 正在运行

CONTAINER ID   IMAGE     COMMAND                  CREATED          STATUS          PORTS                                           NAMES

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

添加restart: unless-stopped作品，但这似乎不是根本原因，阅读此内容后 - https://docs.docker.com/compose/startup-order/，我认为问题在于 mongo-express 取决于 mongo 服务，所以理想情况下它应该在 mongo 运行后启动，但似乎没有针对此问题的优雅解决方案，该depends_on选项将有助于减少问题，但无法完全解决。

检查depends_on选项的限制（或设计），https://docs.docker.com/compose/compose-file/compose-file-v3/#depends_on

引用

在启动 web 之前，depends_on 不会等待 db 和 redis “准备好” - 仅在它们启动之前。如果您需要等待服务准备好，请参阅控制启动顺序以获取有关此问题的更多信息以及解决该问题的策略。

问题似乎是您已经配置了网络。在快速服务器中，它试图连接到在其自己的本地主机上运行的 Mongo 实例（容器的 127.0.0.1 不是您的本地机器）。由于没有 MongoDB 实例在您的快速服务上运行，ECONNREFUSED因此会引发（错误连接被拒绝）。我们需要做的是将 DB 容器放在可从 express 服务访问的网络上并连接到它。您可以在此处的文档中找到有关使用 docker-compose 联网的更多信息。

在这种情况下，我发现最容易做的事情，特别是对于本地开发，是将两个服务“链接”在一起，如下所示：

version: '3'
services:
  mongodb:
    image: mongo
    ports:
      - 27017:27017
    environment:
      - MONGO_INITDB_ROOT_USERNAME=admin
      - MONGO_INITDB_ROOT_PASSWORD=password

  mongo-express:
    image: mongo-express
    ports:
      - 8080:8081
    environment:
      - ME_CONFIG_MONGODB_ADMINUSERNAME=admin
      - ME_CONFIG_MONGODB_ADMINPASSWORD=password
      - ME_CONFIG_MONGODB_SERVER=mongodb
    links: 
        - mongodb:mongodb

然后更改mongoUrlLocal为mongodb://admin:password@mongodb:27017. 请在此处查看文档以获取更多信息。实际上，这会在mongo-express服务中创建一个指向服务的伪 DNS 记录，mongodb因此每当您尝试连接到“mongodb”地址时，您就是在连接到运行数据库的容器。请注意，这仅适用于链接服务，因此您无法从本地计算机连接到“mongodb”。

此外，我建议您执行的操作还有用于数据库连接的环境变量。目前我看到你有ME_CONFIG_MONGODB_SERVER哪些没有使用，mongoUrlLocal并且mongoUrlDocker. 我认为process.env从 docker-compose 文件中提取连接字符串信息然后传递环境变量可能会更好。

例如这样的事情：

const dbServer = process.env.ME_CONFIG_MONGODB_SERVER;
const dbPassword = process.env.ME_CONFIG_MONGODB_ADMINPASSWORD;
const dbUserName = process.env.ME_CONFIG_MONGODB_ADMINUSERNAME;
const dbPort = process.env.ME_CONFIG_MONGODB_PORT;

let mongoUrl = `mongodb://${dbUserName}:${dbPassword}@${dbServer}:${dbPort}`;

好吧，这里的问题显然是 mongo-express 确实在 mongo 尚未准备好时启动了，所以它（mongo-express）无法连接，并保持在失败状态。

  • 使用restart: unless-stopped是一种解决方案，但为此目的并不干净。

要走的路是添加对 mongo-express 的依赖。它应该在 mongo 完成启动后启动，并实现此用途：

depends_on:
      - mongodb
