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. (http://yaml.org/type/null.html)
