[TanmoySG]

Containerize wunderidentityprovider using Docker for easy of use and portability. Further, the Azure Deployment will be torndown and replaced with docker container that can run in the development environment of other services to test integration with wIP.

[Checkpoints]

• [x] Add Dockerfile, define Proper Steps in to Dockerize
• [x] Add docker-compose.yml for better usage using docker-compose up
• [x] Add port mapping and volume mapping
• [x] Add Containerize and Publish Pipeline using GitHub Actions and Github Package Registry
• [x] Add Instructions to Run in README.md
• [x] Replace Manual Demo Section with Docker Usage
• [x] Move Manual Demo to a README of its own. (Track in separate issue)

if __name__ == '__main__':
    app.run(debug=True, host='0.0.0.0')

Use host in app.run() to use the container

expose 5000

run using docker run -p 5000:5000 container-name

and test using curl 1xx.xxx.xxx:wxyz 1xx.xxx.xxx:wxyz being the IP, may also use localhost:5000

Works on Codespaces and Local - tested ✅
