Introduction to Containerizing Angular Applications with Docker

--- title: Angular language-specific guide linkTitle: Angular description: Containerize and develop Angular apps using Docker keywords: getting started, angular, docker, language, Dockerfile summary: | This guide explains how to containerize Angular applications using Docker. toc_min: 1 toc_max: 2 languages: [js] params: time: 20 minutes --- The Angular language-specific guide shows you how to containerize an Angular application using Docker, following best practices for creating efficient, production-ready containers. [Angular](https://angular.dev/) is a robust and widely adopted framework for building dynamic, enterprise-grade web applications. However, managing dependencies, environments, and deployments can become complex as applications scale. Docker streamlines these challenges by offering a consistent, isolated environment for development and production. > > **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 essential 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 an Angular application using Docker. - Set up a local development environment for Angular inside a container. - Run tests for your Angular application within a Docker container. - Configure a CI/CD pipeline using GitHub Actions for your containerized app. - Deploy the containerized Angular application to a local Kubernetes cluster for testing and debugging. You'll start by containerizing an existing Angular application and work your way up to production-level deployments. --- ## Prerequisites Before you begin, ensure you have a working knowledge of: - Basic understanding of [TypeScript](https://www.typescriptlang.org/) and [JavaScript](https://developer.mozilla.org/en-US/docs/Web/JavaScript). - Familiarity with [Node.js](https://nodejs.org/en) and [npm](https://docs.npmjs.com/about-npm) for managing dependencies and running scripts. - Familiarity with [Angular](https://angular.io/) fundamentals. - Understanding of core 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 Angular getting started modules, you’ll be fully prepared to containerize your own Angular application using the detailed examples and best practices outlined in this guide.

This guide provides instructions on how to containerize Angular applications using Docker, covering topics such as setting up a local development environment, running tests in a container, configuring a CI/CD pipeline with GitHub Actions, and deploying to a local Kubernetes cluster. It assumes a basic understanding of TypeScript, JavaScript, Node.js, npm, Angular, and core Docker concepts.
