Dockerizing a React Task: A Hands-On DevOps Implementation

Source: Dev.to | Dec 20, 2025 (UTC)

In this article, I’ll walk through how I built a Dockerized React Task Manager from scratch, emphasizing real-world DevOps practices like containerization, multi-stage builds, and production-ready deployment.

1. Project Overview

Build a React-based Task Manager to track tasks in real time.

Containerize the frontend using Docker and serve it with Nginx.

Set up a backend API placeholder for future integration.

Implement multi-container orchestration using Docker Compose.

This project serves as both a DevOps practice exercise and a production-ready application template.

3. Setting Up the React Environment

I use vite for React
cd frontend
npm create vite@latest . -- --template react
npm install
npm run dev

• Verified the React app works locally.
• Initially displayed default Vite UI with counter and logos

4. Containarized the frontend

# Build stage FROM node:20-alpine AS build WORKDIR /app COPY package*.json ./ RUN npm install COPY . . RUN npm run build # Production stage FROM nginx:alpine COPY nginx.conf /etc/nginx/conf.d/default.conf COPY --from=build /app/dist /usr/share/nginx/html EXPOSE 80 CMD ["nginx", "-g", "daemon off;"]
