search facts by regex

[Alex Bogatu]

Hello!
I spent the last couple of days trying to find a good way to search facts specific to some node based on ragex. For example, in my puppet manifest i need a way to check if there are facts whose names (not values) match a specific regex.  Is there anyone who had this problem before? I know that it might be done using inline ruby code, but i wonder if there is no other solution.

See here:
https://docs.puppetlabs.com/puppet/latest/reference/lang_facts_and_builtin_vars.html#the-factsfactname-hash

Then using the standard lib function keys() on $facts to get an array of
the keys. You can then use the in operator to search.
Alternatively use the standard lib function has_key($facts).

If you are using parser=future you can also iterate over the hash's keys
and values directly.
