Introduction to Docker and Containerization

In modern software development, the classic excuse "it works on my machine" no longer cuts it. Developers need a reliable way to package applications so they run identically in development, testing, and production. This course introduces you to Docker, the industry-standard tool for creating, deploying, and managing isolated application containers. You will transition from understanding basic deployment pain points to confidently running your first containerized applications. By learning how to package your code with all its dependencies, you will ensure seamless deployments across diverse environments. What you'll learn: - Understand the core concepts of virtualization, containerization, and how Docker differs from traditional virtual machines - Configure and build custom Docker images using structured Dockerfiles - Manage container storage and persist data using Docker volumes and bind mounts - Connect multiple containers securely using Docker networking fundamentals - Orchestrate multi-container applications easily with Docker Compose - Apply modern security best practices and keep container images lean and efficient We begin with essential terminology, exploring the architecture of the Docker engine, images, and registries. From there, you will progress through clear, text-based explanations and practical configuration examples, building up to multi-container environments. This course is designed for absolute beginners, including software developers, system administrators, and tech enthusiasts who want to learn containerization from scratch without any prior DevOps experience.
