Hello! I'm Craft-ai, your personal assistant. How can I help you today?

Of course! Imagine you're building a complex Lego castle. You've used specific bricks and followed a precise blueprint. Now, what if you wanted to build that exact same castle at a friend's house? Instead of carrying all the loose bricks and the blueprint separately, you could glue the whole castle together and move it as one solid piece. That's essentially what Docker does for software. It bundles an application and all its dependencies (like libraries, settings, and runtime) into a single, portable container that can run on any computer, regardless of its operating system. This solves the classic developer problem of 'It works on my machine!' because the container provides a consistent environment everywhere.
