 Docker: What is Docker images?

              In simple words, a Docker image is like a snapshot or a blueprint of your entire application and its dependencies. It's a single file that contains all the necessary components to run your software, such as the code, libraries, configurations, and even the operating system.

Imagine an image as a ready-to-use package that holds everything needed to set up and run your application. It's like a recipe that you can use to create multiple identical servings of your software.

With Docker images, you can easily share your application with others, ensuring that everyone uses the exact same setup. It saves you from the headache of dealing with different environments and ensures that your application works consistently, no matter where it's deployed.

In a nutshell, Docker images simplify the process of packaging and distributing your software, making it more convenient and reliable for software developers and system administrators.
