if you're using hiera, why not something like:
foo_data_webfarm_http_servers:
foo1.example.com: {
ip: '1.2.3.4',
port: '80',
}
foo2.example.com: {
ip: '2.3.4.5',
port: '80',
}
foo_data_webfarm_https_servers:
foo1.example.com: {
ip: '1.2.3.4',
port: '443',
}
foo2.example.com: {
ip: '2.3.4.5',
port: '443',
}
class foo::data {
include foo::params
file { 'foo.conf':
path => '/etc/foo.conf',
ensure => 'file',
content => template(foo_conf.erb),
mode => '0555',
}
class foo::params {
$webfarm_http_servers = hiera('foo_data_webfarm_http_servers', '')
$webfarm_https_servers = hiera('foo_data_webfarm_https_servers', '')
}
foo_conf.erb
<% http_servers = scope.lookupvar('foo::params::webfarm_http_servers')
https_servers = scope.lookupvar('foo::params::webfarm_https_servers')
-%>
#
# http servers
<% http_servers.each_pair do |key, hash| -%>
#<%=key%>
IPADDR= <%=hash['ip'] %>
PORT= <%=hash['port'] %>
<% end%>
#
# https servers
<% https_servers.each_pair do |key, hash| -%>
#<%=key%>
IPADDR= <%=hash['ip'] %>
PORT= <%=hash['port'] %>
<% end%>
<% end%>
