If you can centralize all the information, you can do something like this:
vars:
'asdf[somehost]' string => '1.2.3.4';
'asdf[anotherhost]' string => '1.2.3.5';
'ip_address' slist => getindices('asdf');
classes:
'webapp' expression => isvariable("asdf[${sys.host}]");
files:
revproxy::
'/some/file'
edit_line => SomeEdit(${ip_address});
This does not repeat any piece of information.
If you can't centralize the data, you will need to run cf-serverd on
all hosts and look into the peer-to-peer functionality of features
like the remotescalar() special function:
