It also manages such things as creating, removing images, fetching images from the registry of choice, creating, restarting, removing containers and many other things.

Were seeing it more in job requirements, and more companies are starting to incorporate it.

Nowadays it feels like its something so basic and common in the development world that if you dont know about it, you are behind everybody else.

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 Ive heard it has these things like images and containers and its like a virtual machine but not really a virtual machine.

Why do I even need it, and what does all of this have to do with this blue whale after all In this article Ill try to explain: what exactly is docker why you might need it which problems is it trying to solve how is it different from a virtual machine when to use it over a virtual machine and vice versa what are images and containers in general and how they are implemented in docker.

Im 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.

However, while reading this, if you dont get something, or something feels vague, just keep reading, it will all make sense in the end.

My advice about this article would be to read it 2 times to have your aha moments.

Lets take a moment and define some of those names to at least know which one is which.

Docker, Inc docker engine (community enterprise ) docker for Mac docker for windows docker client docker host docker server docker hub docker registry docker compose docker swarm docker machine docker daemon Quite a lot of dockers here, huh Im going to give you a short definition for each of the terms here so you know what they are.

Docker (company) Docker, Inc was co-founded in 2010 by Solomon Hykes (CTO) in San Francisco, and at that time it was called dotCloud, Inc.

In March of 2013 at PyCon, Solomon revealed a new product by dotCloud, Inc called docker.

The motivation as he describes it in his talk (the first ever talk where docker was mentioned) was that people have been very interested in Linux containers and how they could build something with them, but the problem was that Linux containers were very complicated.

At dotCloud, Inc they decided to simplify usage of Linux containers and make them accessible for everybody, so the software docker was born.

They spun off their PaaS business to another company and the rest is history.

For us, we are primarily interested in docker software, not in the company itself, but I think its good to know a little bit of history behind it.

Docker (software) Docker is available in 2 editions: Docker community edition (CE) and Docker enterprise edition (EE).

For development environment and small teams, CE is the way to go, so in this article we wont cover EE.

Docker software consists of 2 separate programs, that is docker engine, also known as docker daemon (because it is, in fact, a daemon, running in the background ) and docker client.

Engine Daemon Docker engine is what actually enables Linux containers to work its the brain of docker so to speak.

Docker engine is responsible for running processes in isolated environments.

For each process, it generates a new Linux container, allocates a new filesystem for it, allocates a network interface, sets an IP for it, sets NAT for it and then runs processes inside of it.
