Hi,
With hiera, you'll need to base all of your logic on fact values.
AFAIK, you can't directly use any regexps, but what you could do to
achieve to same goal is create a custom fact which would get assigned a
specific value if another fact matches a regexp.
Another other solution would be unconditionally include a class, and
have the logic inside that class, to include other classes based on
things like "if $::hostname =~ /^web\d+$/ { include '::foo' }".
Combine the ifs as much as you want, using intermediate booleans to
make things clearer...
HTH,
Matthias
