[Docker] Addition of Dockerfile and Compose

[arya2004]

Description

The backend server has been successfully set up using Express.js. The next step in our development process is to containerize the application using Docker. This will allow the application to run in a consistent environment across different machines.

Task Details

1. Set up Docker for the Project:

   • Create a Dockerfile for the Express.js server.
   • Ensure that all necessary dependencies and configurations are included in the Dockerfile (e.g., Node.js version, environment variables, port configurations).

2. Docker Compose (Optional):

   • If required, create a docker-compose.yml file to simplify the process of running the application, especially if additional services are planned in the future.

3. Environment Variables:

   • Ensure that any required environment variables are handled securely within the Docker setup, either through Docker Compose or a .env file (not included in the image for security reasons).

4. Testing the Docker Setup:

   • Test the Docker setup to ensure that the application can be built and run correctly inside the container.
   • Make sure the necessary ports are exposed for the application to be accessible (e.g., port 3000 for an Express server).

5. Documentation:

   • Add necessary documentation or comments explaining how to build and run the Docker container, including any environment variable configurations.

Acceptance Criteria

• [ ] A working Dockerfile that builds the Express.js application and installs all required dependencies.
• [ ] The application runs successfully within the Docker container and is accessible on the specified port.
• [ ] Environment variables are securely handled in the Docker setup.
• [ ] Clear instructions or comments explaining the Docker setup, including how to build and run the container.

Additional Notes

• Refer to the official Docker Documentation for help with Docker setup.
