Introspection naturally happens in large bulks, after which it's inactive. Small pool for DHCP addresses means that we'll have conflicts due to how dnsmasq distributes them by default - using hashing. This change tells dnsmasq to allocate IP addresses sequentially instead to avoid these conflicts. The drawback of this option is that long-running clients may switch IP addresses if their lease expires. This is not a concern for short introspection process.

Overview
The ironic module is a part of OpenStack, an effort by the OpenStack infrastructure team to provide continuous integration testing and code review for OpenStack and OpenStack community projects as part of the core software. The module itself is used to flexibly configure and manage the baremetal service for OpenStack.
Module Description
Setup
What the ironic module affects:
- Ironic, the baremetal service for OpenStack.
Installing Ironic
puppet module install openstack/ironic
Beginning with ironic
To utilize the ironic module's functionality you will need to declare multiple resources. This is not an exhaustive list of all the components needed. We recommend that you consult and understand the core openstack documentation to assist you in understanding the available deployment options.
# enable Ironic resources
class { '::ironic':
rabbit_userid => 'ironic',
rabbit_password => 'an_even_bigger_secret',
rabbit_host => '127.0.0.1',
database_connection => 'mysql://ironic:a_big_secret@127.0.0.1/ironic?charset=utf8',
}
class { '::ironic::db::mysql':
password => 'a_big_secret',
}
class { '::ironic::keystone::auth':
password => 'a_big_secret',
}
class { '::ironic::client': }
class { '::ironic::conductor': }
class { '::ironic::api':
admin_password => 'a_big_secret',
}
class { '::ironic::drivers::ipmi': }
# alternatively, you can deploy Ironic with Bifrost. It's a collection of Ansible playbooks to configure
# and install Ironic in a stand-alone fashion (for more information visit http://git.openstack.org/openstack/bifrost)
class { 'ironic::bifrost':
ironic_db_password => 'a_big_secret',
mysql_password => 'yet_another_big_secret',
baremetal_json_hosts => hiera('your_hiera_var_containing_bm_json_hosts'),
}
Examples of usage also can be found in the examples directory.
Implementation
puppet-ironic
puppet-ironic is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
Types
ironic_config
The ironic_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/ironic/ironic.conf file.
ironic_config { 'DEFAULT/verbose' :
value => true,
}
This will write verbose=true in the [DEFAULT] section.
name
Section/setting name to manage from ironic.conf
value
The value of the setting to be defined.
secret
Whether to hide the value from Puppet logs. Defaults to false.
ensure_absent_val
If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>
Limitations
Beaker-Rspec
This module has beaker-rspec tests
To run:
shell bundle install bundle exec rspec spec/acceptance
