Subject: [PATCH] Add Dockerfile for project build

Introduced Dockerfile to manage the build process for the project, including its dependencies. This development will standardize the environment, thus making it easier for others to build and run the app. Also added necessary 'passwd' and 'group' files in 'support-files' directory for managing user details in Docker.
