Using Foreman global variables as class parameters

Support
1

Hello,

My name is Daniel and I am in the middle of integrating Foreman in our
company infrastructure. Until now, it is a very smooth process and working
quite well. But I think I might have some misunderstandings when I want to
use Foreman global variables in class parameters:

  1. Foreman, I have a global parameter set myparam -> testvalue_from_foreman
    2 In puppet: notify{'Test', name => $::myparem} -> testvalue_from_foreman

so this is working quite well.

But how do I use global variables in class parameters?

  1. In Foreman, override the class parameter, type string - 'localparam'
    with: $::myparam
  2. In puppet, notify{'Test', name => $localparam} -> $::myparam

How do I get the $::myparam expanded? I already tried in foreman:
"${::myparam}", but I suppose my value is passed to pupped as
'$::myparam'…

Thanks!
Daniel

Hello Daniel,

Foreman allows you to also override the puppet class parameters using smart class params (inside the puppet class edit form).
For more information, take a look at this section of the manual:
http://theforeman.org/manuals/1.8/index.html#4.2.5ParameterizedClasses

How do I get the $::myparam expanded? I already tried in foreman:

Indeed, I read this before posting. However, further testing shows I most
likely misunderstand the 'string' type or it is broken.

Example:
I set a class parameter 'ssl_ca_bundle' as sting, value:
'puppet:///mbox_files/mbox-ssl/ca-bundle-client.crt'

I get:
Error: Failed to apply catalog: Parameter source failed on
File[/etc/pki/tls/certs/ca-bundle-client.crt]: Could not understand source
'puppet:///mbox_files/mbox-ssl/ca-bundle-client.crt': bad URI(is not URI?):
'puppet:///mbox_files/mbox-ssl/ca-bundle-client.crt' at
/etc/puppet/environments/puppettest/modules/confluence/manifests/init.pp:76

Or, using as value a global parameter like ${$::g_ssl_key}
Error: Failed to apply catalog: Parameter source failed on
File[/etc/pki/tls/private/m-box.de.key]: Could not understand source
${$::g_ssl_key}: bad URI(is not URI?): $%7B$::g_ssl_key%7D at
/etc/puppet/environments/puppettest/modules/confluence/manifests/init.pp:67

I work around this by using the array type. For instance,
['puppet:///mbox_files/mbox-ssl/ca-bundle-client.crt'] or
[$::g_ssl_key]

The foreman docs do not go in further detail, but I expected the 'sting'
type to be passed like this to puppet: "value" or even 'value'. Internally
it seems to be escaped for some reason beyond me.
$%7B$::g_ssl_key%7D

Thanks!
