Overview
The cinder 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 its self is used to flexibly configure and manage the block storage service for OpenStack.
Module Description
The cinder module is a thorough attempt to make Puppet capable of managing the entirety of cinder. This includes manifests to provision such things as keystone endpoints, RPC configurations specific to cinder, and database connections. Types are shipped as part of the cinder 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 cinder module affects
- Cinder, the block storage service for OpenStack.
Installing cinder
puppet module install openstack/cinder
Beginning with cinder
To utilize the cinder 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 documentation.
Define a cinder control node
class { 'cinder':
database_connection => 'mysql://cinder:secret_block_password@openstack-controller.example.com/cinder',
default_transport_url => 'rabbit://cinder:secret_password@openstack-controller.example.com:5672',
}
class { 'cinder::api':
keystone_password => $keystone_password,
keystone_user => $keystone_user,
keystone_auth_uri => $keystone_auth_uri,
service_port => $keystone_service_port,
package_ensure => $cinder_api_package_ensure,
bind_host => $cinder_bind_host,
enabled => $cinder_api_enabled,
}
class { 'cinder::scheduler': }
Define a cinder storage node
class { 'cinder':
database_connection => 'mysql://cinder:secret_block_password@openstack-controller.example.com/cinder',
default_transport_url => 'rabbit://cinder:secret_password@openstack-controller.example.com:5672',
}
class { 'cinder::volume': }
cinder::backend::iscsi {
'iscsi_example':
target_ip_address => '10.0.0.2',
}
**Define a cinder storage node with multiple backends **
class { 'cinder':
database_connection => 'mysql://cinder:secret_block_password@openstack-controller.example.com/cinder',
default_transport_url => 'rabbit://cinder:secret_password@openstack-controller.example.com:5672',
}
class { 'cinder::volume': }
cinder::backend::iscsi {'iscsi1':
target_ip_address => '10.0.0.2',
}
cinder::backend::iscsi {'iscsi2':
target_ip_address => '10.0.0.3',
}
cinder::backend::iscsi {'iscsi3':
target_ip_address => '10.0.0.4',
volume_backend_name => 'iscsi',
}
cinder::backend::iscsi {'iscsi4':
target_ip_address => '10.0.0.5',
volume_backend_name => 'iscsi',
}
cinder::backend::rbd {'rbd-images':
rbd_pool => 'images',
rbd_user => 'images',
}
cinder_type {'iscsi':
ensure => present,
properties => ['volume_backend_name=iscsi,iscsi1,iscsi2'],
}
cinder_type {'rbd-images':
ensure => present,
properties => ['volume_backend_name=rbd-images'],
}
class { 'cinder::backends':
enabled_backends => ['iscsi1', 'iscsi2', 'rbd-images']
}
Note: that the name passed to any backend resource must be unique across all backends otherwise a duplicate resource will be defined.
** Using cinder_type **
Cinder allows for the usage of type to set extended information that can be
used for various reasons. We have resource provider for cinder_type
and if you want create some cinder type, you should set ensure to absent.
Properties field is optional and should be an array. All items of array
should match pattern key=value1[,value2 ...]. In case when you want to
delete some type - set ensure to absent.
Implementation
cinder
cinder is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
Types
cinder_config
The cinder_config
provider is a children of the ini_setting provider.
It allows one to write an entry in the /etc/cinder/cinder.conf
file.
cinder_config { 'DEFAULT/api_paste_config' :
value => '/etc/cinder/api-paste.ini',
}
This will write api_paste_config=/etc/cinder/api-paste.ini
in the [DEFAULT]
section.
name
Section/setting name to manage from cinder.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
- Setup of storage nodes is limited to Linux and LVM, i.e. Puppet won't configure a Nexenta appliance but nova can be configured to use the Nexenta driver with Class['cinder::volume::nexenta'].
Development
Developer documentation for the entire puppet-openstack project.
