[React.js](https://react.dev/) is a widely used library for building interactive user interfaces. However, managing dependencies, environments, and deployments efficiently can be complex. Docker simplifies this process by providing a consistent and containerized environment. > > **Acknowledgment** > > Docker extends its sincere gratitude to [Kristiyan Velkov](https://www.linkedin.com/in/kristiyan-velkov-763130b3/) for authoring this guide. As a Docker Captain and experienced Front-end engineer, his expertise in Docker, DevOps, and modern web development has made this resource invaluable for the community, helping developers navigate and optimize their Docker workflows. --- ## What will you learn? In this guide, you will learn how to: - Containerize and run a React.js application using Docker. - Set up a local development environment for React.js inside a container. - Run tests for your React.js application within a Docker container. - Configure a CI/CD pipeline using GitHub Actions for your containerized app. - Deploy the containerized React.js application to a local Kubernetes cluster for testing and debugging. To begin, you’ll start by containerizing an existing React.js application. --- ## Prerequisites Before you begin, make sure you're familiar with the following: - Basic understanding of [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript) or [TypeScript](https://www.typescriptlang.org/). - Basic knowledge of [Node.js](https://nodejs.org/en) and [npm](https://docs.npmjs.com/about-npm) for managing dependencies and running scripts. - Familiarity with [React.js](https://react.dev/) fundamentals. - Understanding of Docker concepts such as images, containers, and Dockerfiles. If you're new to Docker, start with the [Docker basics](/get-started/docker-concepts/the-basics/what-is-a-container.md) guide. Once you've completed the React.js getting started modules, you’ll be ready to containerize your own React.js application using the examples and instructions provided in this guide.
