nornir_flask (Simple NetApp)

This simple Web App will read your Nornirs hosts.yaml inventory file and will render the results in a user friendly HTML Table.

Use Case Description

This would be a good use case for automation engineers to develop a customer care (user) friendly application which can be used to check devices by simply clicking through hyperlinks instead of having to log in into network devices.
In return they will be able to easily and quickly find network device information.

Configuration

The code allows for further customization as well as add more features. Knowledge of Nornir, Flask and HTML/JavaScript is required.
