Overview
|
|
--------
|
|
|
|
The nova module is a part of [OpenStack](https://opendev.org/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 its self is used to flexibly configure and manage the compute service for OpenStack.
|
|
|
|
Module Description
|
|
------------------
|
|
|
|
The nova module is a thorough attempt to make Puppet capable of managing the entirety of nova. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to nova, and database connections. Types are shipped as part of the nova module to assist in manipulation of configuration files.
|
|
|
|
This module is tested in combination with other modules needed to build and leverage an entire OpenStack software stack.
|
|
|
|
Setup
|
|
-----
|
|
|
|
**What the nova module affects:**
|
|
|
|
* [Nova](https://docs.openstack.org/nova/latest/), the compute service for OpenStack.
|
|
|
|
### Installing nova
|
|
|
|
puppet module install openstack/nova
|
|
|
|
### Beginning with nova
|
|
|
|
To utilize the nova module's functionality you will need to declare multiple resources. This is not an exhaustive list of all the components needed, we recommend you consult and understand the [core openstack](https://docs.openstack.org) documentation.
|
|
|
|
```puppet
|
|
class { 'nova':
|
|
database_connection => 'mysql://nova:a_big_secret@127.0.0.1/nova?charset=utf8',
|
|
api_database_connection => 'mysql://nova:a_big_secret@127.0.0.1/nova_api?charset=utf8',
|
|
default_transport_url => 'rabbit://nova:an_even_bigger_secret@127.0.0.1:5672/nova',
|
|
glance_api_servers => 'localhost:9292',
|
|
}
|
|
|
|
class { 'nova::compute':
|
|
enabled => true,
|
|
vnc_enabled => true,
|
|
}
|
|
|
|
class { 'nova::compute::libvirt':
|
|
migration_support => true,
|
|
}
|
|
```
|
|
|
|
Implementation
|
|
--------------
|
|
|
|
### nova
|
|
|
|
nova is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
|
|
|
|
### Types
|
|
|
|
#### nova_config
|
|
|
|
The `nova_config` provider is a children of the ini_setting provider. It allows one to write an entry in the `/etc/nova/nova.conf` file.
|
|
|
|
```puppet
|
|
nova_config { 'DEFAULT/glance_api_servers' :
|
|
value => 'http://localhost:9292',
|
|
}
|
|
```
|
|
|
|
This will write 'http://localhost:9292' in the `[DEFAULT]` section.
|
|
|
|
##### name
|
|
|
|
Section/setting name to manage from `nova.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
|
|
-----------
|
|
|
|
* Supports libvirt, xenserver and vmware compute drivers.
|
|
* Tested on EL and Debian derivatives.
|
|
|
|
Development
|

Beaker-Rspec
|
|
------------
|
|
|
|
This module has beaker-rspec tests
|
|
|
|
To run the tests on the default vagrant node:
|
|
|
|
```shell
|
|
bundle install
|
|
bundle exec rspec spec/acceptance
|
|
```
|
|
|
|
