template_variable_problems

template_variable_problems.rb

In the recipe I have:

template "/etc/zookeeper/zoo.cfg" do
  source "zoo.cfg.erb"
  mode 0644
  variables(:servers => zk_servers)
  Chef::Log.debug "6 zk_servers ==  #{zk_servers}"
end


In the zoo.cfg.erb template I have:

<% if @servers.size > 1 -%>
  <% @servers.each_with_index do |server, i| %>
server.<%= i %>=<%= server[:ipaddress] %>:<%= server[:zookeeper][:peer_port] %>:<%= server[:zookeeper][:leader_port] %>
  <% end -%>
<% else -%>
  <% server = @servers.first -%>
server=<%= server[:ipaddress] %>:<%= server[:zookeeper][:peer_port] %>:<%= server[:zookeeper][:leader_port] %>
<% end -%>

template_variable_problems_log.rb

relevant chef-client log output:


[2012-10-12T10:42:16-05:00] DEBUG: 6 zk_servers ==  [node[zookeeper1.electronicminions.com], node[zookeeper2.electronicminions.com]]



Chef::Mixin::Template::TemplateError (undefined method `size' for nil:NilClass) on line #28:

 26:
 27:
 28: <% if @servers.size > 1 -%>
 29:   <% @servers.each_with_index do |server, i| %>
 30: server.<%= i %>=<%= server[:ipaddress] %>:<%= server[:zookeeper][:peer_port] %>:<%= server[:zookeeper][:leader_port] %>



So why is @servers nil?
