Problem using hiera variable in templates

[Christian Charpentier]

Hi,

I'm trying to use variables stored in hiera files in module templates. I read it's better to avoid to use hiera function in templates so i tried to get the hiera value in the config.pp manifest with a local variable.
Then to use the local variable in the template, but it doesn't work.

common.yaml

    $accounts_conf_filename                = hiera('accounts_conf_filename')
    $accounts_conf_balancer_filename  = hiera('accounts_conf_balancer_filename')
    $crt_filename                                 = hiera('certificate_filename')
    $key_filename                                = hiera('key_filename')

    }
 
    file {"/etc/httpd/conf.d/$accounts_conf_balancer_filename":
        ensure   => file,

    file {'/etc/pki/tls/private/$key_filename':
        ensure   => file,
        content  => template("/etc/puppet/hieradata/$key_filename"),
    }

}

accounts.victorbuckservices.com.conf.erb

<VirtualHost accounts.dev.victorbuckservices.com:80>
   ServerName <% ServerName =  scope.lookupvar('apache::config::servername') %>
    ServerAdmin <% ServerAdmin = scope.lookupvar('apache::config::serveradmin') %>

I also tried syntax as follow:
ServerName <%= scope.function_hiera('ServerName') %>
ServerName <%= @servername %>

But i doesn't works neither.


Any idea or suggestion to make this right?

Cheers,
Christian

It was due to some kind of syntax error (= missing) :
<%=  scope.lookupvar('apache::config::servername') %>
