url_shortener

Building docker-compose based Microservices for a Flask web application

Requirements

To build a user-facing web service that takes a URL and provides a shorter URL, when possible. When resolved, that URL should redirect the user to the original URL.

The service should have a user-facing website (but the graphical design won't matter)
When given a long URL, the service should shorten it and return the shortened URL
Visiting the shortened URL should redirect the visitor to the long URL
You should provide source code as well as a link to a running instance of your service
You do, of course, not need to register a short domain name
