• What is Docker?

What is Docker ?

• There are two ways of looking at Docker. The
  first approach involves seeing Docker containers
  as really lightweight virtual machines, while the
  second approach is to see Docker as a software
  packaging and delivery platform.
• This latter approach has proven a lot more
  helpful to human developers and resulted in
  widespread adoption of the technology.

Overview of Docker Containers

• Traditionally, cloud service providers used
  virtual machines to isolate running applications
  from one another.
• A hypervisor, or host operating system, provides
  virtual CPU, memory and other resources to many
  guest operating systems.
• Each guest OS works as if it is running on an
  actual physical hardware and it is, ideally,
  unaware of other guests running on the same
  physical server.
• However there are several problems with
  virtualization. First, the provisioning of
  resources takes time. Each virtual disk image is
  large and bulky and getting a VM ready for use
  can take up to a minute.
• Second and a more important issue system
  resources are used inefficiently. OS kernels are
  control freaks that want to manage everything
  thats supposedly available to them

Docker as a Developers Tool

• One of the problems developers often deal with is
  the difference between the production server,
  where the applications run, and their own dev
  machines (usually laptops and workstations),
  where applications are developed.
• Lets imagine you have Windows 10 running on
  your desktop but you want to write applications
  for Ubuntu 18.04. Maybe you are using Python v3.6
  to write your application, while the Ubuntu
  server is still running at 3.4.

Docker Overview
There are just too many variables to take into
account and so we use Docker to abstract that
complexity away. Docker can be installed on any
OS even Windows and Mac OS X are well-supported.
So you can package your code into a Docker
image, Run and test it locally using Docker to
guaranteed that the containers that were created
from that Docker image will behave the same way
in production.
