🔑 Key Concepts & Definitions

• Docker: An open-source platform that automates the deployment, scaling, and management of containerized applications, functioning as an engine to run containers on various operating systems.
• Container: A lightweight, standalone, and executable software package that includes an application and all its dependencies, providing isolated environments for running applications.
• Image: A read-only template used to create containers, composed of multiple layers, serving as a blueprint for containers.
• Containerization: The process of packaging applications and their dependencies into containers, enabling consistent execution across different environments without the need for full virtualization.
• Docker Engine: The core component that runs and manages containers, handling image building, container execution, and resource allocation.
• Docker Registry: A storage and distribution system for Docker images, with Docker Hub being the most popular public registry.
