2What 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.
3Overview 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

5Docker 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.
6Docker 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.
