This commit refactors the previous site.pp example.
Adds ring building types and removes the ringbuilding
file.
Remove unnessary comments.
Adds requirement that swift proxy is only configured
after the ring is built.
The previous calls to sope.lookupvar were very
dependeny on the version of puppet used.
These calls have been replaced with the more
reliable and concise has_variable? method.
This commit adds a class, defined resources and
native types that can be used together to manage
the creation, configuration, and rebalancing of
rings.
Creates the following native types:
ring_account_device
ring_container_device
ring_object_device
The implementation of these types is provided
by swift-ring-builder and most of the functionality
is provided by the parent provider (SwiftRingBuilder)
Each of the providers is hard-coded to find the
relevent ring database in /etc/swift. This directory
location can currently not be configured.
Each provider implements self.instances so the
current state can of the ring can be queried from
puppet.
These providers do not handle either the creation
or the rebalancing of the rings, they are intended
to be used in combination with defined resource types
that perform that functionality:
swift::ringbuilder::create
swift::ringbuilder::rebalance
The swift::ringbuilder class is also created as
a part of this commit. This class does the following:
- creates object, account, and container rings
(it uses the same parameters to create these rings)
- creates the rebalance defines
- sets up the following relationships:
for each ring type, create should be applied before
the native types which should refresh the rebalance
