Why Docker?
---------------------------------------------

Docker creates an abstraction layer for the system.
Docker is light-weight, it only installs dependencies that are required for particular applications to run, not even the whole Operating System.
In one command you can install different versions and can remove it.
No dependency error while installing any software because it creates its’ own space and which is abstracted with other installed programs.
Benefits of Docker
---------------------------------------------

Don't worry about "It works on my machine, but not on yours"
Docker image works identical in all environment where Docker is installed
You can run various versions of same image as different containers at same time
