This module provides a way to install and configure Swift storage clusters using puppet. The classes documented in this file will deploy Swift using best practices for a typical deployment.

Both single host and clustered configurations are supported.

Tested Environments

  • Ubuntu 12.04; puppet 2.7.16; Swift 1.4.8




class that sets up base packages and the base /etc/swift/swift.conf.

class { 'swift':
  # shared salt used when hashing ring mappings
  swift_hash_suffix => 'shared_secret',


class that installs and configures the swift proxy server

class { 'swift::proxy':
  # specifies that account should be automatically created
  # this should be set to true when tempauth is used
  account_autocreate = true,
  proxy_local_net_ip = $ipaddress_eth1,
  #proxy_port = '11211',
  # auth type defaults to tempauth - this is the
  # only auth that has been tested
  #auth_type = 'tempauth',


class that sets up all of the configuration and dependencies for swift storage server instances

class { 'swift::storage':
  # address that swift should bind to
  storage_local_net_ip => $ipaddress_eth1,
  devices              => '/srv/node'


Defined resource type that can be used to create a swift storage server instance. In general, you do not need to explicity specify your server instances (as the swift::storage::class will create them for you)

This will configure an rsync server instance and swift storage instance to manage the all devices in the devices directory.

# the title for this server and the port where it
# will be hosted
swift::storage::server { '6010':
  # the type of device (account/object/container)
  type => 'object',
  # directory where device is mounted
  devices => '/srv/node',
  # address to bind to
  storage_local_net_ip => ''


This defined resource was created to test swift by creating loopback devices that can be used for testing

It creates a partition of size [$seek] at base_dir/[$name] using dd with [$byte_size], formats it to be an xfs filesystem which is mounted at [$mnt_base_dir]/[$name]

It then creates swift::storage::devices for each device type using the title as the 3rd digit of a four digit port number :60[digit][role] (object = 0, container = 1, account = 2)

swift::storage::loopback { '1':
  base_dir  => '/srv/loopback-device',
  mnt_base_dir => '/srv/node',
  byte_size => '1024',
  seek      => '25000',
  storage_local_net_ip => ''



class that knows how to build rings.

Creates the initial rings, collects any exported resources, and rebalances the ring if it is updated.

  class { 'swift::ringbuilder':
    part_power     => '18',
    replicas       => '3',
    min_part_hours => '1',


For an example of how to use this module to build out a single node swift cluster, you can have a look at examples/all.pp

This example can be used as follows:

puppet apply examples/all.pp

For an example of how to use this module to build out a multi node swift cluster, you can have a look at examples/site.pp. This file assumes you have a puppetmaster with storeconfigs enabled.

Please note that if you create fewer than 3 storage nodes, you will need to edit the replicas parameter of the swift::ringbuilder instance in the proxy node definition.

Once your puppetmaster is configured, you can provision your nodes with:

puppet agent -t --certname my_role

Verifying installation

This module also comes with a simple Ruby script that validates rather or not your swift cluster is functional.

The script can be run as:

ruby files/swift_tester.rb
