Overview
|
|
--------
|
|
|
|
The openstack_extras 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 add useful utilities for
|
|
composing and deploying OpenStack with the Openstack puppet modules.
|
|
|
|
Module Description
|
|
------------------
|
|
|
|
The openstack_extras module is intended to provide useful utilities to help
|
|
with OpenStack deployments, including composition classes, HA utilities,
|
|
monitoring functionality, and so on.
|
|
|
|
This module combines other modules in order to build and leverage an entire
|
|
OpenStack software stack. This module replaces functionality from the
|
|
deprecated [stackforge/puppet-openstack module](https://github.com/stackforge/puppet-openstack).
|
|
|
|
Setup
|
|
-----
|
|
|
|
### Installing openstack_extras
|
|
|
|
example% puppet module install puppetlabs/openstack_extras
|
|
|
|
### Beginning with openstack_extras
|
|
|
|
Instructions for beginning with openstack_extras will be added later.
|
|
|
|
Implementation
|
|
--------------
|
|
|
|
### openstack_extras
|
|
|
|
openstack_extras is a combination of Puppet manifest and ruby code to delivery
|
|
configuration and extra functionality through types and providers.
|
|
|
|
**HA configuration for Openstack services**
|
|
|
|
This module allows to configure Openstack services in HA. Please refer to the [ha-guide](http://docs.openstack.org/high-availability-guide/content/index.html) for details.
|
|
If you have a Corosync with Pacemaker cluster with several nodes joined, you may want to use an HA service provider which allows you to create the pacemaker resources for Openstack services and run them in HA mode.
|
|
The example HA service configuration for keystone service:
|
|
|
|
```puppet
|
|
openstack_extras::pacemaker::service { 'openstack-keystone' :
|
|
ensure => present,
|
|
metadata => {},
|
|
ms_metadata => {},
|
|
operations => {},
|
|
parameters => {},
|
|
primitive_class => 'systemd',
|
|
primitive_provider => false,
|
|
primitive_type => 'openstack-keystone',
|
|
use_handler => false,
|
|
clone => true,
|
|
require => Package['openstack-keystone']
|
|
}
|
|
```
|
|
This example will create a pacemaker clone resource named `p_openstack-keystone-clone` and will start it with the help of systemd.
|
|
|
|
And this example will create a resource `p_cinder-api-clone` for Cinder API service with the given OCF script template from some `cluster` module:
|
|
|
|
```puppet
|
|
$metadata = {
|
|
'resource-stickiness' => '1'
|
|
}
|
|
$operations = {
|
|
'monitor' => {
|
|
'interval' => '20',
|
|
'timeout' => '30',
|
|
},
|
|
'start' => {
|
|
'timeout' => '60',
|
|
},
|
|
'stop' => {
|
|
'timeout' => '60',
|
|
},
|
|
}
|
|
$ms_metadata = {
|
|
'interleave' => true,
|
|
}
|
|
|
|
openstack_extras::pacemaker::service { 'cinder-api' :
|
|
primitive_type => 'cinder-api',
|
|
metadata => $metadata,
|
|
ms_metadata => $ms_metadata,
|
|
operations => $operations,
|
|
clone => true,
|
|
ocf_script_template => 'cluster/cinder_api.ocf.erb',
|
|
}
|
|
|
|
```
