Docker (company)ĭocker, Inc was co-founded in 2010 by Solomon Hykes (CTO) in San Francisco, and at that time it was called dotCloud, Inc. Quite a lot of dockers here, huh? I’m going to give you a short definition for each of the terms here so you know what they are.

docker engine (community / enterprise ).

Let’s take a moment and define some of those names to at least know which one is which. There are many “docker” names you might hear throughout the internet, and for a newbie it might be overwhelming. Okay enough with that, let’s get started! What is Docker? My advice about this article would be to read it 2 times to have your “aha moments”.

However, while reading this, if you don’t get something, or something feels vague, just keep reading, it will all make sense in the end. I’m going to go through all the concepts in a specific order so that every other topic I explain will require an understanding of the previous concepts.

and how they are implemented in docker.

what are images and containers in general.

when to use it over a virtual machine and vice versa.

how is it different from a virtual machine.

Why do I even need it, and what does all of this have to do with this blue whale after all? No, but seriously, what is this “Docker” thing? Why is everybody so excited about it? What is it even? Can you define it? is this a desktop app? CLI tool? a website? service? is this thing for production or is it a dev tool? Both? I’ve heard it has these things like “images” and “containers” and it’s like a virtual machine but not really a virtual machine. Nowadays it feels like it’s something so basic and common in the development world that if you don’t know about it, you are behind everybody else. We’re seeing it more in job requirements, and more companies are starting to incorporate it. The mental gymnastics to make this a smart move are just unreal.Docker has been a buzzword for tech people for the last several years, and the more times goes by, the more often you hear about it.

then you see things like this: where someone is spinning up individual EC2 instances instead of just paying for Docker Desktop.

I actually started paying for the $5/mo subscription for myself personally just because I do get a lot of value from it. People have been getting significant value out of Docker itself for a long time without paying anything - myself included. I, for one, am happy for Docker and them figuring out a model that allows them to stay around as a company. I suppose it is one thing if you really know what you're doing but you could easily multiply the effort for many people who either don't understand the solution being put in place or need more time to troubleshoot said solution. I've seen people in my own company spend so much time and effort to try to find Docker desktop replacements and just seeing how much time would be spent, multiplied by tens to hundreds of developers on some teams. I almost feel like no matter what tool it is they are using, especially so if it is a VM that needs any level of user management, that people will find it is pretty easy to have the user spend more time (which is money and is not "free" no matter what anyone thinks) than it would have just cost to have Docker Desktop to begin with.
