How would I represent an undef in hiera such that a class parameter will be populated as undef? Like this, but in hiera:
#class testing::cwood1 ( $param1 = undef ) { class testing::cwood1 ( $param1 ) { if str2bool($param1) { notify { 'mn': message => "param1 is ${param1}" } } } I'm dealing with a config file template where most options are always turned off. I'm also trying to get our puppet agent runs to fail with catalog compilation errors if they can't look up a hiera value, so there are no default values in the class parameters. (Exploring if catalog compilation failure is safer than the possibility of populating a config with default values.) If I could list a bunch of obvious 'undef' style items in hiera that might be handier than listing 'false', given that the meaning of 'configitem=false' is different in this config than an absent configitem. Details: In the node yaml doing ~ or null both give me the same result. testing::cwood1::param1: ~ But that parameter isn't looked up. Feb 9 10:18:55 pt1 puppet-agent[22696]: Could not retrieve catalog from remote server: Error 400 on SERVER: Must pass param1 to Class[Testing::Cwood1] at /etc/puppet/environments/production/modules/testing/manifests/init.pp:3 on node pt1.hostopia.com I've checked that the yaml is readable by ruby and the appropriate key shows up with pp as "testing::cwood1::param1"=>nil} so not sure what is up here. When I use the empty string in the yaml the puppet catalog applies but I do not see anything in the log (so the class parameter was accepted). testing::cwood1::param1: '' Not really sure if I'm just mucking about with edge cases and should special-case my template or what.
