Puppet erb hostname returns servername

Question

I want to put the node name in a template. I was expecting the variable @hostname to do so but I get the servername instead.

The master node is a debian wheezy with puppet 3.7.5-1puppetlabs1, the node is wheezy with puppet 2.7.23-1~deb7u3.

I tried this template:

hostname=<%= @hostname %>
fqdn=<%= @fqdn %>
servername=<%= @servername %>

I go to the node and I type:

# puppet agent --test

And that is what is generated:

hostname=puppet

fqdn=enquestes.my.domain
servername=puppet.my.domain

I was expecting hostname would return enquestes, and that is what I understand reading this other question:

puppet node hostname

So I wonder if there is something messed up somewhere. Notice the extra newline after the ''puppet'' hostname. It was not in the template but it gets written in the output. I tried also with:

inline_template('<%= hostname %>')

But it returns puppet instead of the node hostname as I expected.

If I go to the node and I type this:

$ facter | grep -i hostname

I get the expected hostname enquestes. So I wonder maybe I missed something and this is the expected behaviour or is there something wrong in my node or master ?

Thank you for your time.

I found in the manifest I had this from a previous try $hostname = generate('/usr/bin/env','/bin/hostname'). I didn't know it was going in the template. I just commented it and now I get an empty hostname when I run puppet agent. I was exepecting now to get the node name — Francesc Guasch, Apr 15 '15 at 08:50
Perhaps you're obliterating the variable value in some other scope as well? — Felix Frank, Apr 15 '15 at 09:12
Good point, then it should be in one manifests or template ? I tried grep -i hostname * and it shows nothing. — Francesc Guasch, Apr 15 '15 at 13:08
After 24 hours it works as expected. I guess the @hostname was kept in memory or cached somehow. — Francesc Guasch, Apr 16 '15 at 10:01
