Question

我无法解决MongoParseError。

首先我尝试过

mongoose.connect(`mongodb://${process.env.DB_USER}:${process.env.DB_PASSWORD}@db:27017/${process.env.DB_NAME}`, {useNewUrlParser: true});

使我最终遇到此错误

MongoParseError: Unescaped slash in userinfo section

然后我逃脱了所有的斜线

mongoose.connect(`mongodb:\\/\\/${process.env.DB_USER}:${process.env.DB_PASSWORD}@db:27017\\/${process.env.DB_NAME}`, {useNewUrlParser: true});

我最终遇到了无法解决的错误

MongoParseError: Invalid connection string

这是我的index.js

'use strict';

const mongoose = require('mongoose');
mongoose.connect(`mongodb:\\/\\/${process.env.DB_USER}:${process.env.DB_PASSWORD}@db:27017\\/${process.env.DB_NAME}`, {useNewUrlParser: true});

var db = mongoose.connection;
db.on('error', console.error.bind(console, 'connection error:'));
db.once('open', function() {
  console.log('ok');
});

const express = require('express');

// Constants
const PORT = 8080;
const HOST = 'localhost';


var kittySchema = new mongoose.Schema({
  name: String
});

var Kitten = mongoose.model('Kitten', kittySchema);

var silence = new Kitten({ name: 'Test1234' });


// App
const app = express();
app.get('/', (req, res) => {
  res.send(silence.name);
});

app.listen(PORT);
console.log(`Running on http://${HOST}:${PORT}`);

这是docker-compose.yml

version: '3.7'
services:
  web:
    build: .
    command: npm start
    volumes:
      - ./src:/usr/app/
      - ./src/node_modules:/usr/app/node_modules
    ports:
      - 80:8080
    environment:
      DB_NAME: websitedb
      DB_USER: /run/secrets/db_user
      DB_PASSWORD: /run/secrets/db_password
    secrets:
      - db_user
      - db_password
  db:
    image: mongo:latest
    volumes:
      - ./mongo-init.js:/docker-entrypoint-initdb.d/mongo-init.js:ro
    ports:
      - "27017:27017"
    environment:
      MONGO_INITDB_DATABASE: websitedb
      MONGO_INITDB_ROOT_USERNAME_FILE: /run/secrets/db_user
      MONGO_INITDB_ROOT_PASSWORD_FILE: /run/secrets/db_password
    secrets:
      - db_user
      - db_password
volumes:
  mongo:
secrets:
  db_user:
    file: ./db_user.txt
  db_password:
    file: ./db_password.txt

谁能告诉我我在做什么错？

翻阅guide on managing secrets in docker compose，似乎所有秘密都作为安装在/run/secrets/SECRET_NAME中的文件传递到了容器中，建议将路径作为环境变量传递给该文件，然后在您的应用中读取文件：

部署时，Docker会在服务中的/ run / secrets /下挂载文件。这些文件永远不会保留在磁盘中，而是在内存中进行管理。

每个服务都使用环境变量来指定服务应在哪里寻找该秘密数据。

您已将这些机密的路径作为process.env.DB_USER传递，但是要获取实际机密，您需要读取文件：

const fs = require('fs');
const mongoose = require('mongoose');

let dbUser = fs.readFileSync(process.env.DB_USER);
let dbPassword = fs.readFileSync(process.env.DB_PASSWORD);

mongoose.connect(`mongodb://${dbUser}:${dbPassword}@db:27017/${process.env.DB_NAME}`, {useNewUrlParser: true});
