Description

Introduction

Docker is an open-source platform that enables developers to automate the deployment, scaling, and management of applications in lightweight, portable containers. These containers encapsulate an application’s code, libraries, and dependencies, ensuring consistent execution across different environments. Docker simplifies application packaging and deployment, making it an essential tool for modern software development, particularly in DevOps practices, continuous integration/continuous deployment (CI/CD), and microservices architectures.

Prerequisites

• Basic knowledge of operating systems and virtualization concepts.
• Familiarity with command-line interfaces (CLI).
• Understanding of basic software development principles, including version control and application deployment.
• Experience with programming languages such as Python, Java, or Node.js will be helpful but not required.
