compatibility with Puppet 8

[corporate-gadfly]

Describe the Bug

I wasn't ready to make the move to Puppet 8 yet, however, my yum repository mirror mistakenly showed puppetserver-8.0.0-1.el8.noarch.rpm and a yum update updated the puppet version.

Expected Behavior

tagmail should run with Puppet 8

Steps to Reproduce

Steps to reproduce the behavior:

1. Install Puppet 8 RPM on CentOS 8 Stream
2. Logs will show an error:

Environment

• Version 8.0.0
• Platform CentOS 8 Stream
  • mod 'puppetlabs-tagmail', '4.1.0'

Worth mentioning that no errors after downgrading puppetserver to version puppetserver-7.11.0-1.el8.noarch.rpm.

If it helps any, looks like net-smtp is no longer a default gem in Ruby 3.1.

@corporate-gadfly I came across these problems and this issue, and I found a solution.

You'll need the net-smtp gem installed a puppetserver_gem. You can do this in hiera with stdlib module.

---
classes:
- stdlib
stdlib::manage::create_resources:
  package:
    net-smtp: {ensure: installed, provider: puppetserver_gem}

Also, this requires an extra path to ruby-load-path in /etc/puppetlabs/puppetserver/conf.d/puppetserver.conf.

from:

ruby-load-path: [/opt/puppetlabs/puppet/lib/ruby/vendor_ruby]

to:

ruby-load-path: [/opt/puppetlabs/puppet/lib/ruby/vendor_ruby, /opt/puppetlabs/puppet/cache/lib]

I found this path fix via #102

I tried installing net-smtp package via gem and making the /etc/puppetlabs/puppetserver/conf.d/puppetserver.conf change but it is still failed for me after upgrading to Puppet Server 8.

What did work was getting Puppet to install via gem via a module of mine, not sure why it worked, but it did. $gemreqpacks = ['net-smtp'] package { $gemreqpacks: ensure => present, provider => 'puppetserver_gem', }
