Overview

This course introduces Docker as a way to package and run applications in isolated containers, separating them from the underlying infrastructure. It moves from core concepts through to building and running your own Docker image.

Who it's for

Beginners with no prior Docker experience who want to understand containerization before using it in real development or testing workflows.

Key takeaways

What Docker is and why it speeds up shipping, testing, and deploying code
The difference between Docker and a virtual machine
Building a basic image using a Dockerfile, and the distinction between an image and a container
The difference between CMD and ENTRYPOINT in a Dockerfile
A practical example: containerizing the Selenium robot framework

The course progresses from basics to an intermediate hands-on example, giving beginners a concrete containerization project to reference.

About this course

Docker is an open platform for developing, shipping, and running applications. Docker enables you to separate your applications from your infrastructure so you can deliver software quickly. With Docker, you can manage your infrastructure in the same ways you manage your applications. By taking advantage of Docker’s methodologies for shipping, testing, and deploying code quickly, you can significantly reduce the delay between writing code and running it in production.

Docker provides the ability to package and run an application in a loosely isolated environment called a container. The isolation and security allow you to run many containers simultaneously on a given host. Containers are lightweight and contain everything needed to run the application, so you do not need to rely on what is currently installed on the host. You can easily share containers while you work, and be sure that everyone you share with gets the same container that works in the same way.

In this course you will learn what is Docker, Why Docker? i.e. basics of docker

Later we will see how to create a basic image using Dockerfile (intermediate)

Finally you will be able to containerize a docker image.

There are important topics where we covered the difference between

Docker and Virtual Machine

CMD and ENTRYPOINT

IMAGE and Container

Finally we will see what is Dockerfile? How to create an image based on the Dockerfile.

We will also learn how to containerize the selenium robot framework using Dockerfile.
