[Puppet Users] erb logic with a hiera value
so I've set a hiera key, and trying to display some different data in motd
depending on if the value of said key is true or false… it gets set
accordingly.. but my motd template doesn't seem to be properly reacting when
the value of it changes..
it's as if the variable never matches true
not sure what I'm doing wrong here…. I SUSPECT 'true' isn't being perceived as
such somehow…
Can anyone spot what I'm missing?
bash-3.2$ cat /etc/puppetlabs/puppet/modules/core/manifests/values.pp

module.

$foostatus = hiera('core_values_foo')
}

core_values_foo: - true
bash-3.2$ cat hieradata//common.yaml

This is the problem - you're trying to compare a boolean value of true to a
string value of 'true'. Just do something like:
% if foostatus -%
That should work for you :)
| foo is true |
`'
% else -%
| foo is not true |
`'
% end-%
%= foostatus %

Thanks Gary, I knew it was something simple. Appreciate the help % if foostatus == true -% This is the problem - you're trying to compare a boolean value of true to a string value of 'true'.
