2 min readApr 21, 2021

Hello everyone, this is the first introduction part of the zero to hero guide of Docker training. This guide will be split into many parts for the ease of understanding and not to complicate things. This guide will be a beginner friendly and brain friendly guide, you have nothing to worry about anything. I will cover almost everything in Docker in this series.

Prerequisites: You should be breathing now and must have some basic knowledge about Linux commands. Yes, as simple as that.

I will be using Ubuntu as my bare metal OS, I suggest you to use any Linux based kernel to continue this. If you are using Linux, you will be more than enough to start with(If not, use virtual box and fire up a Linux OS in that). Okay, without any further ado, lets jump into it.

Let’s address the elephant in the room first!

What the heck is Docker? Why should we learn it?

Everything we see on this Internet space is a program that is running on top of an OS in a cloud server running somewhere in the world. That is if we want to run anything that we have build, we want an OS. So in this competition world time is money , the more time we consume the more delay we have to bear in the release cycle of our product, it will affect the company survival rate in the market. Simple put faster we come up with an idea , the faster we launch the product/service in the market, we will survive. As we said we need an OS to run a program, typically installing a OS and booting up will take almost 30 min to an hour, and if we want to do things faster we can’t waste time on things like that. This is where Docker come into play, with Docker we can install any operating system in a matter of seconds!! yes, you heared it right. That is the beauty of Docker. You will get your environment ready in seconds and can run any program.

If you are someone who want to work in the DevOps, learning docker is a must.
