Disclaimer

This is not ready to be used.

This is pre-beta code that is actively being developed.

It is currently being developed against swift trunk.

I am actively seeking users who understand that this code is in a pre-alpha state. Feel free to contact me (Dan Bode) at dan < at > puppetlabs com or bodepd < on > freenode.

Any feedback greatly appreciated.

Limitations

• Only been tested for a single node swift install http://swift.openstack.org/development_saio.html

• Only been tested with tempauth

Dependencies:

• Only tested on Ubuntu Natty
• Only tested against Puppet 2.7.9
• Only verified with Swift 1.4.6

module Dependencies

• https://github.com/bodepd/puppet-ssh (this should actaully depend on https://github.com/saz/puppet-ssh and can when pull request https://github.com/saz/puppet-ssh/pull/1 is merged)
• https://github.com/bodepd/puppet-rsync (there is a pull request to merge this into the parent repo: https://github.com/bodepd/puppet-rsync)
• https://github.com/saz/puppet-memcached
• https://github.com/puppetlabs/puppetlabs-stdlib

This module is intended to complement other openstack modules and will eventually be a submodule of the openstack set of modules:

https://github.com/puppetlabs/puppetlabs-openstack

Usage:

swift:

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',
}

swift::proxy:

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 = '127.0.0.1',
  #proxy_port = '11211',
  # auth type defaults to tempauth - this is the
  # only auth that has been tested
  #auth_type = 'tempauth',
}

swift::storage

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

class { 'swift::storage':
  # address that swift should bind to
  storage_local_net_ip => '127.0.0.1'
}

swift::storage::device

defined resource type that can be used to indicate a specific device to be managed

This will configure an rsync server instance and swift storage instance to manage the device (which basically maps port to device)

# the title for this device is the port where it
# will be hosted
swift::storage::device { '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 => '127.0.0.1'
}

swift::storage::loopback

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 [$byte_size], formats it to be an xfs filesystem which is mounted at /src/node/[$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 => '127.0.0.1'

}

swift::ringbuiler

class that knows how to build rings. This only exists as a vague idea

the ring building will like be built as a combination of native types (for adding the drives) and defined types for rebalancing

Example

For an example of how to use this module to build out a single node swift cluster, you can try running puppet apply examples/site.pp (feel free to look at the code to see how to use this module)

There are a few known issues with this code:

• for some reason the ringbuilding script does not run after the manifest fails, you still need to login and run bash /etc/swift/ringbuilder.sh and start swift-proxy
• once swift is running, you can test the swift instance with the ruby script stored in files/swift_tester.rb

This example can be used as follows:

puppet apply examples/site.pp --certname pre_swift

puppet apply examples/site.pp --certname swift_all
