Hi there,
Some information is missing, sorry for that, this is the correct yaml:
nodes:
host1:
ip: xxx.xxx.xxx
cdir: bbb.bbb.bbb
interface: aaa
host2:
ip: yyy.yyy.yyy
cdir: bbb.bbb.bbb
interface: aaa
This yaml is declarated on a Foreman, we use Foreman like Hiera, and it
uses for a template:
<%= @nodes[0][name] %> IPaddr2::<%= @nodes[0]['ip'] %>/<%= @nodes[0]['cidr']
%>/<%= @nodes[0]['interface'] -%>
And its defined on a manifest:
class heartbeat {
template_resources => 'site/heartbeat/resources.erb'
}
I only need the first element to apply, in this case. Thanks for the fast
answer.
Cheers
