Open source Puppet documentation

Before requesting a catalog for a managed node, or compiling one with puppet apply, Puppet collects system information, called facts, by using the Facter tool. The facts are assigned as values to variables that you can use anywhere in your manifests. Puppet also sets some additional special variables, called built-in variables, which behave a lot like facts.

Puppet code can access the following facts when compiling a catalog: To see the fact values for a node, run facter -p on the command line, or browse facts on node detail pages in the Puppet Enterprise console. You can also use the PuppetDB API to explore or build tools to search and report on your infrastructure's facts.

Puppet honors fact values of of any data type. It does not convert Boolean, numeric, or structured facts to strings.
