🐳 Docker Fundamentals Training Course (3 Days)

📌 What is Docker?

Docker is an open-source platform that enables developers to build, package, and deploy applications using containers. Containers bundle an application with its dependencies, ensuring consistency across development, testing, and production environments.

It is widely used in modern DevOps practices alongside tools like Kubernetes, Jenkins, and cloud platforms such as Amazon Web Services.
