add prometheus::server:purge_rules parameter to enable purging in ${config_dir}/rules file resource?

[slvr32]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 7.x
• Ruby: 1.8.x
• Distribution: Oracle Linux
• Module version: 11.2.0

How to reproduce (e.g Puppet code you use)

Create a file resource for $prometheus::server::config_dir/rules in a puppet profile

What are you seeing

notice the file resource conflict with the forge prometheus module

What behaviour did you expect instead

It would be nice to have a prometheus::server::purge_rules toggle for the ${config_dir}/rules file resource, to facilitate purging of old/unmanaged .rules files for a prometheus instance, so that that toggle could be used in the ${config_dir}/rules file resource in server.pp

Output log

Any additional information you'd like to impart

I figured out a solution with a tidy resource, using the following in a related puppet manifest

I have a bit of custom logic to create .rules files in the prometheus::config_dir/rules directory, but a tidy resource following the .rules files creation worked as I was hoping, not deleting .rules files that were already managed by puppet.

$config_dir = lookup('prometheus::config_dir')

tidy { "${config_dir}/rules":
  matches => '*.rules',
  recurse   => true,
}
