Kubernetes vs. Docker

• Kubernetes vs. Docker is a phrase that you hear
  more and more these days as Kubernetes becomes
  ever more popular as a container orchestration
  solution.
• However, Kubernetes vs. Docker is also a
  somewhat misleading phrase. When you break it
  down, these words dont mean what many people
  intend them to mean, because Docker and
  Kubernetes arent direct competitors.
• Docker is a containerization platform, and
  Kubernetes is a container orchestrator for
  container platforms like Docker.

Containerization and Docker

• It is impossible to talk about Docker without
  first exploring containers. Containers solve a
  critical issue in the life of application
  development.
• When developers are writing code they are working
  on their own local development environment. When
  they are ready to move that code to production
  this is where problems arise.
• Containers solved this critical issue of
  portability allowing you to separate code from
  the underlying infrastructure it is running on.
  Developers could package up their application,
  including all of the bins and libraries it needs
  to run correctly, into a small container image.

What is Docker?

• Docker is currently the most popular container
  platform. Docker appeared on the market at the
  right time, and was open source from the
  beginning, which likely led to its current market
  domination. 30 of enterprises currently use
  Docker in their AWS environment and that number
  continues to grow. 
• The Docker File defines everything needed to run
  the image including the OS network
  specifications, and file locations. Now that you
  have a Docker file, you can build a Docker Image
  which is the portable, static component that gets
  run on the Docker Engine.

Advantages of Containers

• Containers have an extremely small footprint.
  The container just needs its application and a
  definition of all of the bins and libraries it
  requires to run.
• Unlike VMs which each have a complete copy of a
  guest operating system, container isolation is
  done on the kernel level without the need for a
  guest operating system. 
• Allowing for applications to become encapsulated
  in self-contained environments allows for quicker
  deployments, closer parity between development
  environments, and infinite scalability.
