What is the difference between an image and a container in Docker?

An image in Docker is a static template that contains all the necessary files, libraries, and configurations to run an application. It's like a snapshot with a pre-installed environment and application.

A container is a running instance of an image, meaning the image in action. The container is isolated, has its own file space and processes, but uses the image as a base.

Example:

• An image is like a class in programming.
• A container is an object created from that class and running in the system.
