I created a test.pp file and put in it a defined type that basically creates a file at /tmp/asdf. I ran puppet apply test.pp and verified that the file got created. However, when I go to puppet resource -t, I don't see that type listed, and I also don't see it when I try:
puppet resource hello_define
Error: Could not run: Could not find type hello_define
I loosely followed this guide:
The puppet resource tool doesn't work with defined types, but only built-in types and custom (Ruby) types that have a properly implemented self.instances method. Have a look at this thread for instance: ref. HTH.
