Need Ruby help for facts (inline_template) --> <%= classes.collect { |k, v| v }.sort.join(" ") %> --> empty

[Denny Fuchs]

Hello,

for my Icinga2, I want to add all classes to vars, like described in https://goo.gl/z798HG (page 41). I added the sjoeboo/puppet-common module, which gives me all classes as a fact:

facter -p classes
["settings", "host.foo.local", "base::root::password", "icinga2::params", "icinga2", ... ]

facter -p classes  --yaml
---
  classes:
    - settings
    - host.foo.local
    - "base::root::password"
    - "icinga2::params"
    - icinga2

I tried the line:

[...]

puppet_classes => inline_template(

'<%= classes.collect { |k, v| v }.sort.join(" ") %>'

),
[...]

so that in the end...

vars.settings
vars.host.foo.local
vars.base
vars.icinga2

is generated for the Icinga2 monitoring host. But in my case, the following is generated instead:

+  vars.puppet_classes = "            "


Maybe, the howto is a bit older and the syntax was changed a bit. We use the Puppet 3.7.2-4 agent.

Any suggestions are very welcome :-)

hi,

I tried to use ".each" instead of ".collect" in the inline_template and than I get "some" output, but only a few classes and not all":

+  vars.puppet_classes = "base::root::password icinga2 icinga2::config icinga2::feature::api icinga2::feature::checker icinga2::feature::mainlog icinga2::install icinga2::params icinga2::repo icinga2::service profile::icinga2::agent settings"

instead of ~30.

strange.

In your example it looks like classes is an array not a hash.  Should be able to just do classes.join(“ “).

I tried it, as the "module" example uses only  .join. It works only for a few classes (13 in numbers):

+  vars.puppet_classes = "base::root::password host.domain.local icinga2 icinga2::config icinga2::feature::api icinga2::feature::checker icinga2::feature::mainlog icinga2::install icinga2::params icinga2::repo icinga2::service profile::icinga2::agent settings"

but

facter -p classes --yaml | wc -l
96

so I have over 90 classes which are not shown. Very strange. Is there a limit ?

hi,

what is very interesting:

If I'm go back to my old

      vars            => hiera_hash('icinga_vars', {}),

and adding to hieradata/common.yaml

  puppet_classes: "%{::classes}"

than I get back all classes, but with the "["  "]"

 vars.puppet_classes = "["settings", .... "augeas::files"]"

So, it seems, that only the classes are listed, which are from the manifest of my class "profile::icinga2::agent", which is included via "include profile::icinga2::agent" in the node manifest.

hi,

I've found the reason. The class profile::icinga2::agent must be loaded after all other classes. Than I get all classes from the node back.
