Querying nested facts with puppetdb

[Tim Skirvin]

I've historically done a lot of puppetdb queries based on legacy
system facts that are going away in puppet 8, e.g.:

https://[server]:8081/pdb/query/v4/facts/lsbmajdistrelease/8

Is there a puppetdb endpoint or trick that I can use to do the
same thing in the new way, with say, os.release.major?

This seems like it will be an important part of retiring legacy,
non-nested facts.

The Inventory endpoint supports querying based on dotted fact paths for both projected values and query filters.

A similar PQL query to what you describe would look like

inventory[certname, facts.os.release.major] {

  facts.os.release.major = "8"
