Ok, thanks. 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

Yes, exaclty. 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/' },
]

Ah, ok, cause I'm passing the first element of the array and not the array
to the Array function? and this is becasue of the quoting, right?
You probably wanted

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?
Hope this helps you get back on track.
