Dockerize repository for easy deployment

[swhasans]

• We need to Dockerize our repository so that it can be easily deployed to different environments. This will make the deployment process smoother and faster, as we won't have to manually set up each environment.

• To achieve this, we need to create a Dockerfile and define the necessary dependencies and configurations. We should also create a docker-compose file to manage multiple containers and set up the environment.

• The work for this task will be done on the task/dockerize-repo branch. Once the work is completed, it should be reviewed and merged into the main branch.

Tasks:

• Create a Dockerfile for the application.
• Build the Docker image from the Dockerfile.
• Test the Docker image locally to ensure it is running correctly.
• Push the Docker image to a Docker registry (e.g. Docker Hub).
• Create a docker-compose.yml file to orchestrate the application and its dependencies (e.g. MongoDB).
• Test the application using the docker-compose setup.
• Update the README.md file with instructions on how to run the application using Docker and docker-compose.
