Hi Andy,
When trying to implement something like Craig Dunn's roles and profiles
pattern with hiera I ended up with:
:hierarchy:
- %{hostname}
- roles/%{role}
- profiles/%{software1}
- profiles/%{software2}
- profiles/%{software3}
- profiles/%{software4}
- profiles/%{software5}
- common
so that I could specify multiple profiles for each role using custom facts
- for example:
system::fact { 'software': [ 'tomcat','activemq'] }
What I'd really like to be able to match a regex like:
- profiles/%{software\d+}
having the elements in the hierarchy treated as a regex before they're
evaluated as a string.
- Keith
