What is a Container? A container is a lightweight, standalone package that bundles an application's code together with all the specific libraries, configurations, and dependencies required to run it. How does it work? • It shares the host operating system's kernel instead of creating a full virtual OS. • It uses "isolation" to run the app in a private space where it cannot see or interfere with other apps. • Since it doesn't boot an entire OS, it starts instantly and uses very little memory. Problem solved: It solves the "it works on my machine" issue. It ensures the software runs exactly the same way, regardless of whether it is on a developer's laptop or a production server. Use Case: If your app needs Python 3.10 but the server only has Python 2.7, the container carries its own 3.10 version inside. The app runs perfectly without needing any changes to the server's settings.
