Formulas are collections of Salt States that have been pre-written by other Salt users and contain generic parameter fields. Formulas allow for reliable reproduction of a specific configuration. Formulas can be installed from RPM packages or an external git repository.

Formulas work best for large, non-trivial, configurations. For trivial tasks, use a state rather than a formula.

Formula data can be managed using the XMLRPC API.

Formulas and states both act as a kind of configuration documentation. When you have written and stored the configuration, they provide a snapshot of your infrastructure.

You can use pre-written formulas as a starting point for your own custom formulas. Pre-written formulas are available from

You can use the Uyuni Web UI to apply pre-existing Uyuni formulas. For more information on the standard formulas available, see salt:salt-formulas-standard.adoc.

Alternatively, you can write your own custom formulas. For more information on custom formulas, see salt:salt-formulas-custom.adoc.
