Dashi_v2

An MVP attempt to create network device discovery and poller written in Python3 and using native or widely supported and known libraries. For the time being, only Cisco IOS(XE) is supported, although it was a personal choise so nothing is stopping you extending this functionality (please refer to Scrapli documentation for supported platforms: https://github.com/carlmontanari/scrapli - big thanks to: @carlmontanari).

Create Django user:

docker exec -it dashi_v2 /opt/venv/bin/python3 /opt/dashi_v2/manage.py createsuperuser
Username: your_username
Email address: your_email
Password: **************
Password (again): **************
Superuser created successfully.
