Docker is the hottest infrastructure technology to hit the tech world in a long time.  The appeal of Docker is that it allows the infrastructure team to utilize the capacity of the servers to near full capacity.  Docker is a container.  A container is like a micro virtualization minus the operating system.  It only contains enough infrastructure to host an app, without the fat.  Hence the term container is used to describe it.



Here are the steps to install Docker on a Ubuntu Server:

1.  Open the Ubuntu terminal, then type the following command to switch to the super user:
     sudo su



2.  Now get the latest update for Ubuntu by typing apt-get update

3.  To install Docker type the following command in the terminal
     apt-get install -y docker.io


4.  Once the installation is complete type service docker status












Now we have Docker installed and running on Ubuntu.  It was pretty simple wasn't it?
