Nornir inventory file creation

[suhaibasaeed]

Clab currently auto generates an Ansible inventory file which can be used with Nornir via the nornir-ansible plugin. This creates an extra dependency upon this python library. If clab was able to auto-create a Nornir hosts.yaml inventory file it would mean the default SimpleInventory plugin could be used which is already included in the Nornir core package thus removing any dependencies.

Creating this issue to track this new feature request that I will attempt myself and raise a PR for.

Is there a contributing guide or the like available?

No dev/contributing guide, unfortunately.
But the inventory creation is just a matter of exercising a Go template against the containerlab data.
For example, here is where it all starts for the ansible inventory

containerlab/clab/inventory.go
