Containerizing a Web Application
Walk through the process of Dockerizing a typical web application, including its frontend, backend, and database components.
Containerizing Web Apps
Welcome to containerizing a web application! In this lesson, we'll walk through how to package a complete web application, including its frontend, backend, and database, into Docker containers.
This is a crucial step for modern development, enabling consistency across environments and simplifying deployment.
Web App Architecture
A typical web application usually consists of several components working together. For our example, we'll focus on a common three-tier architecture:
- Frontend: The user interface (e.g., React, Vue, Angular) that runs in the browser.
- Backend: The server-side logic (e.g., Node.js, Python Flask, Java Spring) that handles business logic and API requests.
- Database: Stores and manages application data (e.g., PostgreSQL, MySQL, MongoDB).
