exec and variables

[Helmut Schneider]

Hi,

I want to exec something with a variable. If found the following link
and tried to implement:

https://stackoverflow.com/questions/33557093/puppet-notify-a-class-with-parameters

file { "${apacheConfPath}/conf-available/${file}":
mode => '0640',
owner => $rootUID,
group => $rootGID,
source =>
"puppet:///modules/my_apache/${operatingsystem}/${apacheConfPath}/conf.d/${file}",
# notify => a2enmod["$file"],
# notify => a2enmod['99-status.conf'],
}
exec { "a2enconf_${title}":
path => '/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin',
refreshonly => true,
command => "a2enconf ${title}",
# subscribe => File['99-status.conf'],
subscribe => File["$file"],
}

Error: Failed to apply catalog: Could not find dependency
File[99-status.conf] for Exec[a2enconf_my_apache::config_files] at
/etc/puppetlabs/code/modules/my_apache/manifests/config_files.pp:130

Can someone point me to the right direction?

Thank you!

Sure. When you make a reference (the upper case File syntax), it has to point to a thing that exists. The reference is a resource type (File) and a resource title (99-status.conf), but you've not defined a resource with that title. Basically, it's like making a symlink to a file that doesn't exist. To fix it, you just need to change your code so the reference and the resource title agree on a title.

Read more about relationships at https://puppet.com/docs/puppet/5.5/lang_relationships.html and about the reference syntax at https://puppet.com/docs/puppet/5.5/lang_data_resource_reference.html

That helped, thanks:

$filesConfd0640 = [
"99-status.conf",
]
$filesConfd0640.each |String $file| {

file { "${apacheConfPath}/conf-available/${file}":
mode => '0640',
owner => $rootUID,
group => $rootGID,

content => epp("${module_name}/etc/apache2/conf.d/${file}.epp",
{ apacheCfg => $apacheCfg, apacheConfPath => $apacheConfPath }),
notify => Exec['/usr/local/bin/apache.sh -c restart']
}
exec { "a2enconf ${file}":

path => '/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin',
refreshonly => true,

command => "a2enconf ${file}",
subscribe => File["${apacheConfPath}/conf-available/${file}"],
}
}
