What is Docker?
Docker is an open-source platform designed to help developers build, ship, and run applications inside containers.
A container is a lightweight, standalone, and executable package that includes everything an application needs to run—code, runtime, libraries, dependencies, and configurations—all bundled together.
Why Use Docker?
Here are some key benefits:
Consistency Across Environments: “It works on my machine” is no longer an excuse.
Speed & Efficiency: Containers start in seconds, not minutes.
Portability: Run your container anywhere—on a laptop, server, or cloud.
Isolation: Containers keep apps and services isolated from one another.
Simplified CI/CD: Perfect for automating testing, deployment, and rollback processes
