웹 어플리케이션 도커 빌드

 

node.js 데모 서버 생성

// index.js
const express = require('express');
const app = express();
const port = 3000;

app.get('/', (req, res) => res.send('Hello form Node.js Server'));

app.listen(port, () => console.log(`Example app listening at http://localhost:${port}`));

 

express 모듈 추가

// package.json
{
  "name": "eks",
  "version": "1.0.0",
  "description": "",
  "main": "index.js",
  "scripts": {
    "test": "echo \"Error: no test specified\" && exit 1"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "express": "^4.17.1"
  }
}

 

Dockerfile 생성

FROM node:10

WORKDIR /usr/src/app
COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 3000
CMD [ "node", "index.js" ]

 

빌드
