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',
}
```
