Overview
--------
The trove module is a part of [OpenStack](https://github.com/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.
Module Description
------------------
Setup
-----
**What the trove module affects:**
* [Trove](http://docs.openstack.org/developer/trove/), the database service for OpenStack.
### Installing trove
puppet module install openstack/trove
Implementation
--------------
### trove
trove is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
### Types
#### trove_config
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.
```puppet
trove_config { 'DEFAULT/backlog' :
value => 4096,
}
```
This will write `backlog=4096` in the `[DEFAULT]` section.
##### name
Section/setting name to manage from `trove.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>`
#### trove_conductor_config
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.
```puppet
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.
##### name
Section/setting name to manage from `trove.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>`
#### trove_guestagent_config
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.
```puppet
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.
##### name
Section/setting name to manage from `trove.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>`
#### trove_taskmanager_config
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.
```puppet
trove_taskmanager_config { 'DEFAULT/network_driver' :
value => trove.network.neutron.NeutronDriver,
}
```
This will write `network_driver=trove.network.neutron.NeutronDriver` in the `[DEFAULT]` section.
##### name
Section/setting name to manage from `trove.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
-----------
Security
--------
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.
Beaker-Rspec
------------
This module has beaker-rspec tests
To run:
``shell
bundle install
bundle exec rspec spec/acceptance
``
