Further troubleshooting proved this to be simple ignorance on the data
structure coming from foreman. The correct syntax is below, where the
static 'host' hash needed to be part of the variable. It might be helpful
to add to the blog post or create more formal documentation with examples
for the ruby-challenged folks 
<% i=0 -%>
<% nodearray.each do |vhash| %>
server.<%= i %>=<%= vhash['host']['name'] %>:2388:3888
<% i=i+1 -%>
<% end -%>
