Project folder ke andar ek file banaye:

Dockerfile FROM node:20

WORKDIR /app

COPY package*.json ./

RUN npm install

COPY . .

EXPOSE 3000

CMD ["node", "server.js"]

Agar aapka main file app.js hai toh:

CMD ["node", "app.js"]

STEP 2 — Create .dockerignore

Isse unnecessary files Docker image me copy nahi hoti.

.dockerignore node_modules npm-debug.log .env Dockerfile docker-compose.yml

STEP 3 — Build the Docker Image

Terminal me project folder me jao:

docker build -t mynodeapp .

✅ STEP 4 — Run the Docker Container docker run -p 3000:3000 mynodeapp

Now open browser:

👉 http://localhost:3000

Your Node.js app is running inside Docker!

💠 BONUS: Docker + MongoDB (docker-compose)

Agar Node app MongoDB bhi use karta hai, toh best way hai docker-compose use karna.

docker-compose.yml version: '3.8'

services: app: build: . ports: - "3000:3000" environment: - MONGO_URL=mongodb://mongo:27017/mydb depends_on: - mongo

mongo: image: mongo ports: - "27017:27017"

Run:

docker-compose up --build
