1. Python in Netdisco - (was: Re: Issue installing latest
netdisco - poetry error) (Oliver Gorwits)
--- Begin Message ---
Hi Muris
Good question! So I guess there are a few motivations for opening up to
Python integrations.
First, as I mentioned, is that people coming to Netdisco as potential code
contributors are more familiar with Python (than Perl). So, if they ask for
a feature, we can suggest they write a patch in Python.
Second, there are new Python libraries it's very interesting to start using
- like netmiko+ntc-templates for CLI gathering data. These things don't
exist in Perl or are no longer maintained.
Third, we have to start somewhere, so just depending on Python and getting
users through installing that is a massive step. The same goes for
developers like me - getting familiar with Python, and things still to come
like Python database interface, is useful.
OK, there is not a lot implemented in Python today, but we have to start
somewhere :-). I am sure this is a better approach than going "big bang"
with Netdisco 3.x as I doubt many people would upgrade, because the
features would be essentially the same.
I accept that this has recently eroded a bit of the "very easy to install"
claim for Netdisco, but as I also said, we had similar issues early in the
2.x days and occasionally since with Perl and database libraries, and it's
just a case of tweaking docs, then we'll be back to "easy" again.
Personally I like the containers anyway (with podman) so there's almost
zero OS hacking needed.
Kind regards
Oliver.
