How to get an array index in erb template in puppet

Question

I need to be able to generate following content of the file (for zookeeper installation):

server.1=$zk.server1.full.hostname:2888:3888
server.2=$zk.server2.full.hostname:2888:3888
server.3=$zk.server3.full.hostname:2888:3888

when I have an array of server hostnames (example shows # of servers = 3). I tried something like following:

<% @regionserver_list.each do |this_server| -%>
server.  =<%= this_server %>:2888:3888
<% end -%>

That seems not correct as and I am struggling with getting an array index (need to start from 1). The point here is that the list of servers will be variable so I cannot use workaround with putting fixed template here for time being. I am stuck on this, can someone help?

Thx

This works:

<% @quorumserver_list.to_enum.with_index(1).each do |this_server, idx| -%>
<%= "server.#{idx}=#{this_server}:2888:3888" %>
<% end -%>
