This issue will mention, the deployment steps that need to be taken for production release.

Use of nginx server for deployment with docker environment

1. Create an nginx container
2. Configure it as entry point for public access
3. Create production build from using npm and point it to Nginx server

Initially flask app was running in development env and same was deployed in production. As per recommendation, we should implement gunicorn which support wsgi interface. When app was running with default flask server, it shutdown automatically. Need to check similar behaviour for gunicorn

[Crispae]

With gunicorn, application run as daemon works fine. No issue of automatic shutdown
