Containerization Class – 5 February

Task: Running Java Application Using Docker

Objective

To create a Docker image for a Java application and execute it using Docker commands.

Description

In this experiment, a Java program was containerized using Docker. A Dockerfile was created to automate the build and execution process. The image was built and run using different Docker commands, including interactive mode for debugging.
