pupept environment filter

[Gustavo]

Hi,

In old mcollective, we used puppet environment filters, because we generated facts.yaml with an ERB template using scope.to_hash, and could type, i.e.:

   mco find -F environment=dev 

Now with choria, I've noticed that generated-facts.yaml doesn't include puppet environment, because it is not a fact.

What is the recommended way to achieve this with choria? I'm thinking about a custom fact wich returns the configured puppet environment of the node.

Thanks!

A custom fact might be your only option yes I am afraid, its a bit out of our control

Heed this warning when setting up your fact:

https://puppet.com/docs/puppet/6.4/lang_facts_and_builtin_vars.html#server-facts

Overriding  $::environment may have unintended consequences. 

Also if you are using an external ENC and that is configured to control the environment that your clients are in then your cached fact can only be accurate to your puppet run interval rather than the choria facts.yaml generation interval. (Hope that makes sense)

Cheers

Matt

Thanks Matt, R.I.

I suspected that risk, we’ll assume it because we are in full control of the nodes and don’t use ENC. Another option is to modify the facts.yaml generator script to make it extensible with custom logic, but it sounds cumbersome.

Yeah - for sure at that point we're just generating a new type of facts :P might as well use the actual fact system.
