openstack tests/site.pp fails to apply - Error: Duplicate declaration: Database_user[@localhost] is already declared

[snowch]

I'm following the instructions on https://forge.puppetlabs.com/puppetlabs/openstack

$ yum -y install puppet

$ puppet module install puppetlabs/keystone
$ puppet module install puppetlabs/openstack

# apply the fix from https://bugs.launchpad.net/puppet-openstack/+bug/1263292

$ puppet apply /etc/puppet/modules/openstack/tests/site.pp --certname openstack_all

The error I get is as follows:

Error: Duplicate declaration: Database_user[@localhost] is already declared in file /etc/puppet/modules/mysql/manifests/server/account_security.pp at line 13; cannot redeclare on node openstack_all
Error: Duplicate declaration: Database_user[@localhost] is already declared in file /etc/puppet/modules/mysql/manifests/server/account_security.pp at line 13; cannot redeclare on node openstack_all

Here's the problem:

The problem isn't in openstack. It's on puppetlabs-mysql.

my machine fqdn is localhost.localdomain and hostname is localhost

In puppetlabs-mysql you have the following code in account_security.pp:

database_user { [ "root@${::fqdn}", 'root@127.0.0.1', 'root@::1',
                    "@${::fqdn}", '@localhost', '@%' ]:
    ensure => 'absent',
    require => Class['mysql::config'],
  }
  if ($::fqdn != $::hostname) {
    database_user { ["root@${::hostname}", "@${::hostname}"]:
      ensure => 'absent',
      require => Class['mysql::config'],
    }
  }

So, in database_user { ...} he's adding @localhost, and in the if, he's adding @${::hostname} which is also localhost.

Possible solutions:

1: change install_modules.sh to switch back to 0.5.0 version (by the way, latest version is 2.1!!!
2: change your hostname to something else than localhost
3: alter the if ($::fqdn != $::hostname) to something like if ($::fqdn != $::hostname && $::hostname != 'localhost')
