Docker

What is Docker

Docker is a tool used to create, run, and manage applications in containers
It helps to run applications in isolated environments

Why Docker

works on any system
lightweight compared to virtual machines
fast deployment
easy to scale

Docker vs Virtual Machine

Docker:
uses containers
lightweight
shares host OS
Virtual Machine:
uses full OS
heavy
slower

simple:
Docker = lightweight container
VM = full system

Container

container is a running instance of an image
it contains everything needed to run the application

Image

image is a blueprint of a container
used to create containers
