Hi Henrik, first of all, thanks for your answer.

Then: notify {"test $name" : message => "static_served: ${apache[static_served]}", } produces: defined 'message' as 'static_served: [static]' *I need to enclose the hash in curly braces otherwise it shows the whole hash like:* defined 'message' as 'Message {enable => true, servername => application, static_served => [static]}[static_served]' You give the reduce an array with a hash in it, and you then append to > that array with an array containing a hash.

That's what I need (if I have not missunderstood it) to pass tot he proxy_pass parameter in the apache forge module: proxy_pass => [ { 'path' => '/a', 'url' => 'http://backend-a/' }, { 'path' => '/b', 'url' => 'http://backend-b/' }, ] [...] > > I make this an array using any2array (array un puppet 5) so I can still > > call the reduce function:: > > > > $var=(Array("${apache['static_served']}")) > > > > so the /reduce /line now looks like: > > > You are asking Array to create an array out of a string.

This is indeed confusing as you have already gone off the road. > So, at the end it was as simple as calling the reduce function like: $apache['static_served'].reduce (I as using a more larger hiera data and, in the very first application, the static_serverd array was empty, so reduce was failling all the time cause the array was empty... Damn!! now the code looks like: if $apache['static_served'] { $_proxy_pass = $apache['static_served'].reduce([ { 'path' => '/', 'url' => "http://localhost:${port}/"; } ]) |$memo, $value| { $memo + [ { 'path' => "/$value/", 'url' => '!' } ] } }else{ $_proxy_pass = [ { 'path' => '/', 'url' => "http://localhost:${port}/"; } ] } notify { "PROXY: $name" : message => $_proxy_pass, } But the reduce is now not working: Notice: {"path"=>"/", "url"=>"http://localhost:56902/"} Notify[PROXY: application]/message: defined 'message' as { 'path' => '/', 'url' => 'http://localhost:56902/' } what am I doing wrong now? BTW, I find the hash notation/manipulation a little confusing... According to https://puppet.com/docs/puppet/5.4/lang_data_hash.html it must be as simple as: $key[$value] And quotes should be used in "keys" when they are strings, but in the above example: $var = Array($apache['static_served']) you are quoting the $value when it's a array and not a string... what is the generic rule for quoting in hashes?
