Course Description

           Docker is a platform that allows developers to build, deploy, and run applications using containers. Containers are lightweight, standardized units that package an application and its dependencies, ensuring consistency across different environments. Docker streamlines the development process by enabling rapid application deployment, scaling, and versioning, while also enhancing isolation and security.
