Creating a Docker container for the NestJS application involves packaging the application and its dependencies into a Docker image

Describe the solution you'd like

• Create a Dockerfile in the root directory of the NestJS application
• Build a Docker image from the Dockerfile
• Run a Docker container from the Docker image & ensure the application is accessible from the outside
