Hi all, I'm using puppet 5.3.
I'd like to build proxy_pass array of hashes using the *reduce *puppet built-in function <https://puppet.com/docs/puppet/5.5/function.html#reduce>and picking the values from a nested hash in hiera. I first played a little bit with the reduce function: $dirs = ['static','media','photos'] $proxy = $dirs.reduce([ { 'path' => '/', 'url' => "http://localhost: ${port}/" } ]) |$memo, $value| { $memo + [ { 'path' => "/$value/", 'url' => '!' } ] } notify { "MemoOut: $proxy" : ;} If I puppet apply the above code the output looks like: Notice: MemoOut: [{path => /, url => http://localhost:189/}, {path => /static/, url => !}, {path => /media/, url => !}, {path => /photos/, url => !}] Notice: /Stage[main]/Main/Node[default]/Notify[MemoOut: [{path => /, url => http://localhost:189/}, {path => /static/, url => !}, {path => /media/, url => !}, {path => /photos/, url => !}]]/message: defined 'message' as 'MemoOut: [{path => /, url => http://localhost:189/}, {path => /static/, url => !}, {path => /media/, url => !}, {path => /photos/, url => !}]' *To my eyes this is an array of hashes, and that's what I need to pass to the apache vhost define.* So, now I want to pick the array (list of directories) from a nested hash in hiera that look like: application: apache: enable: true servername: application static_served: - static I have a define that picks the above hash.... The array with the list of directories becomes "${apache['static_served']}" inside teh define. I can print it using notice ${apache['static_served']}": Notice: static_served: application [static] This looks like an array but *is_array *says that this is *not *an array anymore. And this is my first question, why it is not an array anymore? 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: $_proxy_pass = $var.reduce([ { 'path' => '/', 'url' => "http://localhost: ${port}/" } ]) |$memo, $value| { $memo + [ { 'path' => "/$value/", 'url' => '!' } ] } And here is where everythiong starts to make even less sense: If I print the output (using notice $_proxy_pass and ) and I get a weird output: Notice: /Stage[main]/.../Python::Virtualenv[application]/Notify[PROXY_PASS: [{path => /, url => http://local host:11080/}, {path => /[/, url => !}, {path => /s/, url => !}, {path => /t/, url => !}, {path => /a/, url => !}, {path => /t/, url => !}, {path => /i/, url => !}, {path => /c/, url => !}, {path => /]/, url => !}]]/message: defined 'message' as 'PROXY_PASS: [{path => /, url => http://localhost:11080/}, {path => /[/, url => ! }, {path => /s/, url => !}, {path => /t/, url => !}, {path => /a/, url => !}, {path => /t/, url => !}, {path => /i/, url => !}, {path => /c/, url => !}, {path => / ]/, url => !}]' reduce is taking all letters from "static" instead of 'static" as the first (an uniqe) element from the array.... Later, in my code, I configure the proxy_pass in the apache:vhost like: apache::vhost { "${apache['servername']}": [...] proxy_pass => "$_proxy_pass", [...] But, in the apache file, the proxy pass parameters looks like ProxyPass path url ProxyPassReverse path url ProxyPass path url ProxyPassReverse path url [...] So it's picking the keys from the hashes in the above array of hashes and not the values. I don't understand what is going on. Any help will be appreciated. Best, Arnau -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
