🚀 How to Dockerize a React App with NGINX for CI/CD Pipelines | GitLab CI/CD Series Ep. 6

Welcome to Episode 6 of our GitLab CI/CD Series, where we dive deep into dockerizing a React application to run on a NGINX web server inside a Docker container! This is a crucial step as we build the foundation for automating our deployment pipeline using GitLab CI/CD in future episodes.
If you've ever wondered how to efficiently deploy a React app in a production-ready environment, Dockerizing it with NGINX is the perfect solution! In this video, we’ll walk you through the entire process from start to finish, setting up your app to be easily deployed in Docker containers.
In this episode, you’ll learn:
How to Set Up Docker: Install and configure Docker on your local machine.
Creating a Dockerfile for React: Step-by-step guide on writing a Dockerfile to build and serve your React app in a container.
Using NGINX to Serve React: Why NGINX is a great choice for serving static files and how to configure it properly to serve the production build of your React app.
Optimizing the Docker Container for Production: Tips for optimizing your Docker image, improving performance, and reducing the size of your container.
Building & Running the Docker Container: See how to build your Docker image and run your container locally to verify everything works as expected.
Preparing for CI/CD Integration: This dockerized app will serve as the base for automating your deployment pipeline in the next episode using GitLab CI/CD.
By the end of this tutorial, you’ll have a React app running inside a Docker container with NGINX as the web server, ready for integration into your CI/CD pipeline. This sets the stage for the next episode, where we’ll automate the deployment and delivery process using GitLab CI. 🚀
Why Dockerize a React App with NGINX?
When you use Docker to containerize your app, you create a self-contained environment where your app and its dependencies are bundled together. This means you can run the app anywhere without worrying about compatibility issues. By pairing Docker with NGINX, you can serve your React app as static files in a highly efficient and scalable manner. NGINX is an industry-standard web server known for its high performance, which makes it perfect for production environments.
This tutorial is a perfect fit for:
Frontend developers looking to understand Docker and NGINX deployment.
DevOps enthusiasts who want to build efficient CI/CD pipelines.
React developers preparing their apps for production and automation with GitLab CI.
Here's the step-by-step breakdown:
1. Dockerizing the React App:
Setting up Docker: Install Docker and make sure it's working.
Create the React build: We’ll run npm run build to create a production build of your React app.
Writing the Dockerfile: Learn how to write a Dockerfile that will:
Use an official Node.js image to build the React app.
Copy the build output into an NGINX server to serve it as a static site.
2. NGINX Setup for React:
Configure NGINX: We’ll configure NGINX to point to the build folder of your React app, ensuring it serves the files correctly.
Adjust NGINX settings: Learn how to modify the NGINX configuration for optimal performance, including caching, routing, and error handling.
3. Build and Run the Docker Container:
Build the Docker image: Run docker build to create the image.
Run the container locally: Learn how to run your Docker container and access the React app via a web browser to ensure everything is working.
4. Preparing for GitLab CI/CD:
The final Dockerized app will be used in the next episode to show how to automate deployments with GitLab CI/CD pipelines. This is a key milestone in setting up a fully automated deployment pipeline for your React app.
