This isn't Linux-specific, but it is possible to input a YANG model, and some external data, and produce a usable Python data structure. napalm-yang (https://github.com/napalm-automation/napalm-yang) is an example of doing this via NAPALM output via profiles that handle the parsing to/from device native data structures, with differing levels of support: https://napalm-yang.readthedocs.io/en/latest/root/supported_models/index.html#profiles -- Brandon Ewing (nicot...@warningg.com) pgpgnOqNxvXWD.pgp Description: PGP signature
Re: YANG daemeon for Linux
YANG is a data modelling language and not a method for configuring Linux, though it can be used as a part of one. I am unaware of any open source software that implements a complete solution for parsing the YANG into a model, allowing the manipulation of that models data, and configuring the system to match that model. clixon (www.clicon.org), and it's companion CLI tool cligen, are toolkits to provide a parts of the solution, but they require a large amount of code to be complete. clixon parses the YANG into an XML schema and provides for the manipulation of the data via RESTCONF/NETCONF. clixon also has hooks to call routines to configure the system according to the model data, but not the actual calls. the companion cligen allows you to define a CLI language to manipulate the data, but a language is not provided. disclaimer: I am a contributor to clixon/cligen, the maintainer of its FreeBSD port, and a user of this software in a commercial product.

Re: YANG daemeon for Linux
Could you define "render"? If you're looking to take a YANG model (which one?) and configure Linux kernel networking features with it, I can't recall having seen something that does this. I have been working on a side project (which I'm hoping to bring to a hackathon) to take Linux networking and map it to OpenConfig - but this is maexceptionally embryonic.

Looking for an agent on Linux that will render YANG models, so I can provision networking on Linux.
