Docker Fundamentals Course Outline
Overview
You will learn the difference between the container and the virtual machine. This course will take you through the life cycle of the container and the various stages of development. Moreover, this course will train you to install Docker on various platforms, will create your first container, image, push and pull to the registry hub, will learn how to install your own local registry, volumes, container networking, orchestrating containers, and will learn how to debug your containers. You will build an HTTP server image, run as a service, and connect to it. Also, Finally, you will learn how to create
a swarm and prepare your containers for production.
