Docker is a containerization platform that allows you to package your application and its dependencies into a single image. This makes deploying your application to any environment easy, regardless of the underlying infrastructure. Kubernetes is an open-source system for automating the deployment, scaling, and management of containerized applications. It provides a way to orchestrate multiple containers running on a cluster of hosts. This Docker and Kubernetes training course teaches students how to use these technologies to create and deploy applications quickly and easily.
