The trove 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 database service for OpenStack.
What the trove module affects:
- trove, the database service for OpenStack.
puppet module install openstack/trove
trove is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
The trove_config provider is a child of the ini_setting provider. It allows one to write an entry in the /etc/trove/trove.conf file.
trove_config { 'DEFAULT/backlog' :
value => 4096,
}This will write backlog=4096 in the [DEFAULT] section.
Section/setting name to manage from trove.conf
The value of the setting to be defined.
Whether to hide the value from Puppet logs. Defaults to false.
If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>
The trove_conductor_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/trove/trove-conductor.conf file.
trove_conductor_config { 'DEFAULT/auth_url' :
value => http://localhost:5000/v2.0,
}This will write auth_url=http://localhost:5000/v2.0 in the [DEFAULT] section.
Section/setting name to manage from trove.conf
The value of the setting to be defined.
Whether to hide the value from Puppet logs. Defaults to false.
If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>
The trove_guestagent_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/trove/trove-guestagent.conf file.
trove_guestagent_config { 'DEFAULT/trove_auth_url' :
value => http://localhost:5000/v2.0,
}This will write trove_auth_url=http://localhost:5000/v2.0 in the [DEFAULT] section.
Section/setting name to manage from trove.conf
The value of the setting to be defined.
Whether to hide the value from Puppet logs. Defaults to false.
If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>
The trove_taskmanager_config provider is a children of the ini_setting provider. It allows one to write an entry in the /etc/trove/trove-taskmanager.conf file.
trove_taskmanager_config { 'DEFAULT/network_driver' :
value => trove.network.neutron.NeutronDriver,
}This will write network_driver=trove.network.neutron.NeutronDriver in the [DEFAULT] section.
Section/setting name to manage from trove.conf
The value of the setting to be defined.
Whether to hide the value from Puppet logs. Defaults to false.
If value is equal to ensure_absent_val then the resource will behave as if ensure => absent was specified. Defaults to <SERVICE DEFAULT>
For security reasons, a separate in-cloud RabbitMQ cluster should be set up for trove to use. The reason for this is that the guest agent needs to communicate with RabbitMQ, so it is not advisable to give instances access to the same RabbitMQ server that the core OpenStack services are using for communication.
Please note that puppet-trove cannot check if this rule is being followed, so it is the deployer's responsibility to do it.
