Affected Puppet, Ruby, OS and module versions/distributions

Puppet: 4.10.12

Distribution: CentOS 7.6.1810
Module version: 9.1.0

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

  class { 'rabbitmq':
    ssl                      => true,
    ssl_port                 => 5671,
    ssl_cacert               => '/etc/ssl/certs/ca-bundle.crt',
    ssl_cert                 => "/etc/ssl/_.${::location}.crt",
    ssl_key                  => "/etc/ssl/_.${::location}.key",
    ssl_verify               => 'verify_peer',
    ssl_fail_if_no_peer_cert => false,
    management_ssl           => false,
    environment_variables => {
      'RABBITMQ_USE_LONGNAME' => 'true',
    }

...

{
  rabbitmq_user { 'dev':
    password => $rabbitmq_user_password,
    provider => 'rabbitmqctl',
    tags     => 'monitoring',
  }

  rabbitmq_vhost { 'dev':
    ensure   => present,
    provider => 'rabbitmqctl',
  }
  rabbitmq_user_permissions { ['dev@dev', 'admin@dev', "${bsg_rabbit::monitor_user}@dev"]:
    configure_permission => '.*',
    read_permission      => '.*',
    write_permission     => '.*',
  }
}

What are you seeing

Error: Failed to apply catalog: Cannot parse invalid user line: warning: the VM is running with native name encoding of latin1 which may cause Elixir to malfunction as it expects utf8. Please ensure your locale is set to UTF-8 (which can be verified by running "locale" in your shell)

What behaviour did you expect instead

vhosts/users created if needed

I've tried to run the commands that appear to be failing from the command line, but I'm having trouble getting the syntax correct. Here's what I've tried:

/sbin/rabbitmqctl eval 'rabbit_access_control:check_user_pass_login(list_to_binary("dev"),list_to_binary("dev"))'
Error (argument validation): "syntax error before: "
Arguments given:
	eval rabbit_access_control:check_user_pass_login(list_to_binary("dev"),list_to_binary("dev"))

It's because Rabbitmq's client tools seem to have problems with the language being set a certain way at the system level. While this really is more of a system config issue, we did add a workaround to set LC_ALL to en_US.UTF-8 by default:

puppet-rabbitmq/data/common.yaml

Lines 82 to 83 in 75574b8

    
           rabbitmq::environment_variables: 
        
             'LC_ALL': 'en_US.UTF-8'

#694
rabbitmq/rabbitmq-server#1572

Since you're overriding this, you can either reconfigure your language settings system-wide, or add the value above to environment_variables instead of overriding it. We tried to take a relatively conservative approach to setting this, so that users could override it if they needed to.

Thanks! I set it at both the system-wide level and included it in the environment stanza just to be safe and that seems to have worked.
