What is docker and why do we use it for containerising applications

Question

Accepted Answer

Docker is a platform for developing, shipping, and running applications in containers.

Docker allows applications to be isolated in containers, making them portable and easy to deploy across different environments.
Containers share the host OS kernel but run as isolated processes, providing lightweight and efficient virtualization.
Docker simplifies the process of packaging applications and their dependencies, ensuring consistency in development and production environments.
It enables developers to build, ship, and run applications quickly and reliably, improving collaboration and deployment speed.
Example: Using Docker to containerize a web application allows developers to easily replicate the environment on different servers or machines.
