Re: [Puppet Users] how to use variables elsewhere that's defined in a define() type?
Okay, here comes the follow-up question.
I've changed the zpack_installer, which doesn't do any inline_template()
things any more, instead it looks something like this now:
define installer::zpack_installer($sure='present',
$inst='false',
$zp_ver, $zp_rep) {
}
and then:
class packages::zenpacks::core {
$zpack_list = keys($hr_zpack_core)
## $hr_zpack_core is the hash, comes from nodes.pp
installer::zpack_installer { $zpack_list:
zp_ver = inline_template(%=
@hr_zpack_core[@name]['ver'].to_s.chomp %),
zp_rep = inline_template(%=
@hr_zpack_core[@name]['rep'].to_s.chomp %),
require = Installer::Zpack_installer[ inline_template(%=
@hr_zpack_core[@name]['req'].to_s.chomp %) ],
}
}
But it's failing with: err: Failed to parse inline template: undefined
method `[]' for nil:NilClass
I think, the problem is coming from the @name bit. Is it right way of doing
it?
if I do the same thing in a ruby console, replacing @name with a 'key', I
get exactly what I expect. Any pointer??

Any pointer?? Again - my proposal is to strive for a create_resources() based solution without *any* need to resort to templating. From the data you supplied, there is just no reason for neither invoking to_s nor chomp on your hash values. -- You received this message because you are subscribed to the Google Groups Puppet Users group.

Re: [Puppet Users] how to use variables elsewhere that's defined in a define() type?
I never used the create_resources() and trying to get my head around it.
So, how do I [re]write my define() type to work with create_resources() to
do the same thing similar to this:
class packages::zenpacks::core($pkgs_hash) {
define installer::zpack_installer($sure='present',
$inst='false',
$zp_ver, $zp_rep)) {
package { $name:
ensure = $zp_ver,
require = [
Yumrepo[ $zp_rep ],
Package[ 'zenpack-tools', 'patchutils' ],
];
}
...
...
}
create_resources(installer::zpack_installer, $pkgs_hash)
}
For my purpose, I think I still need to use inline_template() for the rqed
key.
When I install the individual zenpacks, I actually need to do this to
complete the installation:
installer::zpack_installer {
'zenpack-digmonitor':
require = Installer::Zpack_installer[ 'zenpack-apachemonitor' ];
}
How do I handle that?

[Puppet Users] How to use variables elsewhere that defined in a define() type?
I have a class something like this, where I'm passing a [hiera] hash (
zpack_hash) to it:
class installer::zenpack($zpack_hash) {
define zpack_installer($sure='present', $inst='false') {
$z_pack = $installer::zenpack::zpack_hash[$name]
$zp_ver = inline_template(%= @z_pack['ver'].to_s.chomp %)
$zp_repo = inline_template(%= @z_pack['rep'].to_s.chomp %)
$zp_rqed = inline_template(%= @z_pack['req'].to_s.chomp %)
package { $name:
ensure = $sure ? { present = $zp_ver, default = $sure },
notify = Exec[ 'refresh_zenpack_daemons',
'create_default_conf' ],
require= [
File[ '/opt/zenpack/etc/global.conf' ],
Yumrepo[ $zp_repo ],
];
}
}
$my_zpack_list = keys($zpack_hash)
zpack_installer { $my_zpack_list: }
}
Later in my module, how can I use any of the variables (e.g. $zp_repo) that
are already defined in the zpack_installer? I tried something like this:
class zenoss_four::packages::zenpacks::core {
$hr_zenoss_zpack_core = hiera_hash('zenoss_four::zpack_core',
undef)
class { 'installer::zenpack':
zpack_hash = $hr_zenoss_zpack_core,
require= [
Yumrepo[
$installer::zenpack::zpack_installer::zp_repo
],
File[ '/opt/zenoss/etc/global.conf' ],
Zenoss_four::Installer::Zenpack::Zpack_installer[
$installer::zenpack::zpack_installer::zp_rqed ],
];
}
}
but that's not working; throwing in errors like:
err: Failed to apply catalog: Could not find dependency Yumrepo[undef] for
Class[Installer::Zenpack]
on the lines that marked in red. It works just fine if I comment out these
two lines. any help/suggestion from any one?

Re: [Puppet Users] how to use variables elsewhere that's defined in a define() type?
Thanks Felix, for the heads up!
I was also thinking along the line that variables define() type variables
are not accessible from elsewhere.
w.r.t. inline_templates, what else would you suggest? The hiera hash that
I'm using here is something like this:
zpack_four::zpack_core:
zenpack-apachemonitor:
ver: latest
repo: zenoss-four-%{environment}
req: zenpack-apachemonitor
zenpack-digmonitor:
ver: latest
repo: zenoss-four-%{environment}
rqed: zenpack-apachemonitor

That looks nice. Why don't you structure your define zpack_installer()
so that you can use
create_resources('zpack_installer', $hash)
As for variable value reuse - you should rethink your requirements. The
class cannot require resources it declares itself.
As for the yumrepos, that makes more sense (I guess?) but for that you
want to
1. create a custom function that consumes your hash and returns the
repo names
2. write that to a variable (which stores an array value then) so that
you can
3. require Yumrepo[$my_repo_list]
