#confine(hash) ⇒ void

This method returns an undefined value.

Confines a provider to be suitable only under the given conditions. The hash describes a confine using mapping from symbols to values or predicate code.

  • fact_name => value of fact (or array of facts)

  • `:exists` => the path to an existing file

  • `:true` => a predicate code block returning true

  • `:false` => a predicate code block returning false

  • `:feature` => name of system feature that must be present

  • `:any` => an array of expressions that will be ORed together

Examples:

confine :operatingsystem => [:redhat, :fedora]
confine :true { ... }
