How to Dockerize a React app

A very simple and short guide to dockerize a React app.

Create a new React app

$ npx create-react-app dockerized-react-app

Cd into your project

$ cd dockerized-react-app

Create a file named Dockerfile

FROM node:alpine

WORKDIR '/app'

COPY ./package.json ./

RUN npm install

COPY . .

CMD ["npm", "run", "start"]

Create a docker-compose file docker-compose.yml

version: '3'

services:

  app:
    container_name: my-dockerized-react-app
    build:
      context: .
      dockerfile: Dockerfile
    volumes:
      - '.:/app'
      - '/app/node_modules'
    ports:
      - 3000:3000

Build your container

$ docker-compose up -d --build

Go to http://localhost:3000/
