In this session, we will learn what is Docker and what was the need for it. We will also take a look at the benefits of Docker, and the concept behind containerization. We will learn some core Docker concepts such as Docker images, Dockerfiles, Docker Hub, etc. I will also show the Docker commands in action in the terminal and we will also take a look at an actual Dockerfile being used in an open-source project. Finally, we will take a high-level look at the Docker architecture and understand how things work in Docker and what is the flow of commands.

6. Introduction
Solution?
Containerization: A container is a standard unit of software that
packages up code and all its dependencies so the application runs
quickly and reliably from one computing environment to another.

Docker: I will wrap your application inside a magical box and that box will
be able to run on any environment.

8. Concepts
Docker Image: It is a blueprint for the container. You can create your own
images or can use the ones created by others. You can also use existing
images as base image for your image. To build your own image, you
create a Dockerfile.

for the creation of an image.
