Containerizing your apps using Docker

Most people are familiar with Virtual Machines (VM). A VM is a program that runs like a separate computer within a computer. A physical computer can run multiple VMs, allowing it the ability to emulate different operating systems all running at the same time. VMs allow developers to run their apps in a totally isolated environment, ensuring that their apps would be able to run without problems regardless of the configurations of the host computer.

A Docker container works very much like a VM. However, a Docker container does not require a full instance of the OS (which is needed by a VM). And unlike a VM, a Docker container shares the host system’s kernel with other containers, and it offers OS-level virtualization. In this half-day course, you will experience Docker hands-on. You will learn how to create Docker containers from Docker Images hosted on the Docker Hub. You will also learn how to customize your own Docker Image for your own development purposes.
