What is docker

Docker is a containerization platform which we can build the applications and deploy the code.and it is an open source platform.it enables developers to package applications into the containers. Docker applications run in containers that can be used on any of the system.It is a platform for creating and managing containers that are isolated from one another but can communicate via defined channels. using docker to ship and run your containers is a low-cost way of building software more efficiently.

What is Container? 

A container is a package of software that includes everything needed to run an application.it contains all the necessary elements to run in any environment. containers virtualize the os and run from anywhere.A single container might be used to run from a small microservice or s/w process to larger application.A container is a standard unit of software that packages up code and all its dependencies so the application runs quickly. images become containers when they run on Docker Engine.
