Overview
The swift module is a part of Stackforge, an effort by the Openstack infrastructure team to provide continuous integration testing and code review for Openstack and Openstack community projects not part of the core software. The module itself is used to flexibly configure and manage the object storage service for Openstack.
Module Description
The swift module is a thorough attempt to make Puppet capable of managing the entirety of swift. This includes manifests to provision such things as keystone, stroage backends, proxies, and the ring. Types are shipped as part of the swift module to assist in manipulation of configuration files. The classes in this module will deploy Swift using best practices for a typical deployment.
This module is tested in combination with other modules needed to build and leverage an entire Openstack software stack. These modules can be found, all pulled together in the openstack module. In addition, this module requires Puppet's exported resources.
Setup
What the swift module affects
- swift, the object storage service for Openstack.
Installing swift
example% puppet module install puppetlabs/swift
Beginning with swift
You much first setup exported resources.
To utilize the swift module's functionality you will need to declare multiple resources. The following is a modified excerpt from the openstack module. This is not an exhaustive list of all the components needed, we recommend you consult and understand the openstack module and the core openstack documentation.
Defining a swift storage node
class { 'swift':
swift_hash_suffix => 'swift_secret',
}
swift::storage::loopback { ['1', '2']:
require => Class['swift'],

Usage
Class: swift
Class that will set up the base packages and the base /etc/swift/swift.conf
class { 'swift': swift_hash_suffix => 'shared_secret', }
####swift_hash_suffix
The shared salt used when hashing ring mappings.
Class swift::proxy
Class that installs and configures the swift proxy server.
class { 'swift::proxy':
account_autocreate => true,
proxy_local_net_ip => $ipaddress_eth1,
port => '11211',
}
####account_autocreate
Specifies if the module should manage the automatic creation of the accounts needed for swift. This should be set to true if tempauth is also being used.
####proxy_local_net_ip
This is the ip that the proxy service will bind to when it starts.
####port
The port for which the proxy service will bind to when it starts.
Class: swift::storage
Class that sets up all of the configuration and dependencies for swift storage server instances.
class { 'swift::storage': storage_local_net_ip => $ipaddress_eth1, }
####storage_local_net_ip
This is the ip that the storage service will bind to when it starts.
Class: swift::ringbuilder
A class that knows how to build swift rings. Creates the initial ring via exported resources and rebalances the ring if it is updated.
class { 'swift::ringbuilder':
part_power => '18',
replicas => '3',
min_part_hours => '1',
}
####part_power
The number of partitions in the swift ring. (specified as the power of 2)
####replicas
The number of replicas to store.
####min_part_hours
Time before a partition can be moved.
Define: swift::storage::server
Defined resource type that can be used to create a swift storage server instance. If you keep the sever names unique it is possibly to create multiple swift servers on a single physical node.
This will configure an rsync server instance and swift storage instance to manage the all devices in the devices directory.
swift::storage::server { '6010':
type => 'object',
devices => '/srv/node',
storage_local_net_ip => '127.0.0.1'
}
####namevar
The namevar/title for this type will map to the port where the server is hosted.
####type
The type of device, e.g. account, object, or container.
####device
The directory where the physical storage device will be mounted.
####storage_local_net_ip
This is the ip that the storage service will bind to when it starts.
Define: swift::storage::loopback
This defined resource type was created to test swift by creating a loopback device that can be used a storage device in the absent of a dedicated block device.
It creates a partition of size [$seek
] at basedir/[$name
] using dd with [$byte_size
], formats is to be a xfs filesystem which is then mounted at [$mnt_base_dir
]/[$name
].
Then, it creates an instance of defined class for the xfs file system that will eventually lead the mounting of the device using the swift::storage::mount define.
swift::storage::loopback { '1':
base_dir => '/srv/loopback-device',
mnt_base_dir => '/srv/node',
byte_size => '1024',
seek => '25000',
}
####base_dir
The directory where the flat files will be stored that house the file system to be loop back mounted.
####mnt_base_dir
The directory where the flat files that store the file system to be loop back mounted are actually mounted at.
####byte_size
The byte size that dd uses when it creates the file system.
####seek
The size of the file system that will be created. Defaults to 25000.
Verifying installation
This modules ships with a simple Ruby script that validates whether or not your swift cluster is functional.
The script can be run as:
ruby $modulepath/swift/files/swift_tester.rb
Implementation
swift
swift is a combination of Puppet manifest and ruby code to delivery configuration and extra functionality through types and providers.
Limitations
- No explicit support external NAS devices (i.e. Nexenta and LFS) to offload the ring replication requirements.
Development
Developer documentation for the entire puppet-openstack project.
