Custom facts per node.. only via /etc/facter/facts.d/fact_xyz.txt per node?

[Hubert Schmoll]

Hello everyone,

here's what i wanna accomplish: 

i am havin 4 so called servergroups

- ci

- dev

- stage

- production

and i want them to have specific facts depending on the group they are in. 

so in every node i created a file /etc/facter/facts.d/servergroup.txt, containing e.g.

servergroup=stage 

where then a 

facter -d servergroup in the clienthost

gives me an:

stage 

on puppet master, my hiera.yaml looks like this:

:hierarchy:

  - "servergroup/%{::servergroup}"

  - "nodes/%{::clientcert}"

  - common

and i've got on my hieradata a folder servergroup with an file stage.yaml, which, then again, holds:

message: '***           Preparing STAGE environment           ***'

repo_stage_enabled: '1'

repo_prod_enabled:  '0'

nrpe_allowed_hosts: '192.168.3.4'

my module which installes a nrpe uses then these values. like:

$nrpe_allowed_hosts     = hiera('nrpe_allowed_hosts')

so far this works, every stage node gets this values, productive of ci nodes get different values. all good.

What  i do not like is that i have on each node to create the file "/etc/facter/facts.d/servergroup.txt".

I'd rather like to have this information which servergroup each node belongs on my puppetmaster. 

Any ideas? Use ENC? Create kinda custom facts on the puppet master ?

Thanks and best regards

Hubert

An ENC can be used to insert a sort of "Puppet Master defined Fact" (which is actually a top scope variable/parameter) before catalog compilation. Note that this will never appear in "facter -p" on the Agents, because it's not really a Fact.

Code:

https://gist.github.com/lukebigum/20231e70545a298b7dc5

And the data file looks like:

[root@master ~]# head -n10 /etc/puppet/roles.yaml
#Managed by Puppet
---
host.example.com:
parameters:
role: woof
server.example.com:
parameters:
role: cows
