Because of dependencies, code built on one computer may not work properly on another machine. The containerization principle helps to solve this issue. With containerization, an application is packaged and wrapped with all of its system settings and dependencies as it is built and deployed.
When you want to run the program on a different device, you can use the container, which provides a bug-free environment because all the modules and dependencies are bundled together. Docker and Kubernetes are two of the most well-known containerization environments.
