[quinnjr]

Affected Puppet, Ruby, OS and module versions/distributions

• Puppet: 6.28.0
• Ruby: 2.7.0p0
• Distribution: Ubuntu 20.04
• Module version: v4.3.0

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

define dsi::nginx::vhosts::rails(
  $app_name             =   $title,
  $server_name          =   [$app_name],
  $www_root             =   "/var/www/${app_name}/current/public",
  Nginx::UpstreamMemberServer $upstream_sockets     =   "unix:///var/www/${app_name}/shared/tmp/sockets/puma.socket",
  $ssl                  =   false,
  $ssl_cert_path        =   "/etc/ssl/${app_name}.bundle.crt",
  $ssl_key_path         =   "/etc/ssl/${app_name}.key",
  $read_timeout         =   90,
) {

  validate_string($app_name)
  validate_array($server_name)
  validate_string($www_root)
  validate_bool($ssl)
  validate_string($ssl_cert_path)
  validate_string($ssl_key_path)

  nginx::resource::upstream { "${app_name}_socket":
    ensure        => present,
    members    => {
      'puma' =>  {
        server => $upstream_sockets
      }
    },
    queue_timeout => '10s'
  }

What are you seeing

Pattern matching for a valid Unix socket is not being accepted by the module.

What behaviour did you expect instead

I expect a valid Unix socket to be matched

Output log

Error: Could not retrieve catalog from remote server: Error 500 on SERVER: Server Error: Evaluation Error: Error while evaluating a Resource Statement, Dsi::Nginx::Vhosts::Rails[itglue]: parameter 'upstream_sockets' expects a match for Pattern[/^unix:\/([^\/\0]+\/*)[^:]*$/], got 'unix:///var/www/itglue/shared/tmp/sockets/puma.socket' (file: /etc/puppet/modules/itglue/manifests/webserverenv.pp, line: 15) on node itg-oregon-qa-web-i-0d81b7f5e83463752.itglue.com

Any additional information you'd like to impart

Pattern matching on /^unix:[\/]{3}[\w\d\/\-\_\.]+$/ works as expected
