Duration : 3 Days

What You Will Learn:

The purpose of this course is to teach you the life cycle of the container and the various stages of development. By installing Docker on various platforms.

You 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. You will also learn how to debug your containers by building an HTTP server image, run as a service, and connect to it. Together with learning how to create a swarm and prepare your containers for production.
