This simple Web App will read your Nornirs hosts.yaml inventory file and will render the results in a user friendly HTML Table.
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.
The code allows for further customization as well as add more features. Knowledge of Nornir, Flask and HTML/JavaScript is required.
Clone the repository into your Workstation:
git clone https://github.com/veprimk/nornir_flask.git
cd nornir_flask/
python3.8 -m venv venv
source venv/bin/activate
pip install -r requirements.txt
chmod 777 start_app.sh
./start_app.sh
Create environment:
create_environment.bat
Install dependencies
pip install -r requirements.txt
Start APP
start_app.bat
Each device is an anchored link which has been crafted to pass the device name as a parameter to the Flask url route decorator which then passes further to the function which calls Nornir get_facts function.
Results then are again rendered in the HTML Table:
Create or edit a Nornir Inventory based on the given example in hosts.yaml and groups.yaml files and then simply start the application.
The hosts.yaml file contains the details to IOS XE on CSR1000V Always-On which is available from DevNet Sandbox and that can be used to test the application.
