Dockerizing Any Application Using Dockerfile - Full Step by Step Process to make docker image:

What is the Dockerfile?
Dockerfiles are instructions. They contains all of the commands used to build an image.

Docker images consist of read-only layers.
Each represents a Dockerfile instruction.
Layers are stacked.
Each layer is a result of the changes from the previous layer.
Images are built using the docker image build command.

Basic Linux Shell Scripting:

What is Shell?
The shell executes a program in response to its prompt. When you give a command, the shell searches for the program, and then executes it. For example, when you give the command ls, the shell searches for the utility/program named ls, and then runs it in the shell. The arguments and the options that you provide with the utilities can impact the result that you get. The shell is also known as a CLI, or command line interface.

Types of shells:
Primaryly there is two types of shell:
Bourne shell − If you are using a Bourne-type shell, the $ character is the default prompt. 
It has sub categories: Bourne shell (sh), Korn shell (ksh), Bourne Again shell (bash), POSIX shell (sh)
