项目结构如下
- testapp
--- docker-compose.yml
--- dockerfile
--- src
----- index.js
----- package.json
index.js
'use strict';
const MongoClient = require('mongodb').MongoClient;
const express = require('express');
// Constants
const PORT = 8080;
// App
const app = express();
app.get('/', (req, res) => {
res.send('Hello world\n');
});
app.listen(PORT);
console.log(`Running on Port:${PORT}`);
package.json
{
"name": "testapp",
"version": "0.0.1",
"description": "Testapp",
"author": "hi there",
"main": "index.js",
"scripts": {
"start": "node index.js"
},
"dependencies": {
"express": "^4.16.4",
"mongodb": "^3.2.3"
}
}
dockerfile
FROM node:12-alpine
WORKDIR /usr/app
COPY package*.json ./
RUN npm install
COPY . .
EXPOSE 8080
docker-compose.yml
version: '3'
services:
web:
build: .
command: npm start
volumes:
- ./src:/usr/app/
- /usr/app/node_modules
ports:
- 80:8080
我已经阅读了此,但我无法解决此问题.无论我尝试使用哪个模块,我都会遇到此错误:mongodb,spdy等.在本地没有docker的情况下,testapp正常运行.但是我不知道我在用docker做错了什么.谁能帮我吗?
I have alread read this stackoverflow thread but I couldn't solve this issue. I'm getting this error no matter what module I'm trying to use: mongodb, spdy, etc. Locally without docker the testapp is working. But I don't know what I'm doing wrong with docker. Can anyone help me?
推荐答案
具有node_modules的卷文件夹映射,并确保已复制/创建了mongo文件夹
Have volume folder mapping for node_modules and ensure it has mongo folder copied / created
version: '3'
services:
web:
build: .
command: npm start
volumes:
- ./src:/usr/app/
- ./src/node_modules:/usr/app/node_modules
ports:
- 80:8080
