You can then deploy the container on any machine that has Docker installed, and your application will run without any issues. Docker containers are lightweight, portable, and self-sufficient, meaning they contain all the necessary components of an application, including code, libraries, and dependencies, without needing to rely on the host operating system. However, when you try to deploy the application on a different machine, you realize that the machine does not have the same libraries and dependencies installed, and your application fails to run. You have written code in Java/Python and have installed several libraries and dependencies to run the application. Let's say you are a developer working on a web application.
