In I228216a0b55ff2d384b281d9ad2a61b93d58dab9 we split
out just the Controller software config in an effort
to provide hooks for alternate implementations (puppet).
This sort of worked but caused quirky ordering issues
with signal handling. It also causes problems for Tuskar
which would prefer to think of these nested stacks and
not have us split out just the software configs like this.
This patch moves all the controller related stuff for
our two implementations:
controller.yaml: is used by os-apply-config (uses the
tripleo-image-elements)
controller-puppet.yaml: uses stackforge puppet-* modules for
configuration
By duplicating the entire controller in this manner we make
it much easier to create dependencies and implement proper
signal handling. The only (temporary) downside is the duplication
of parameters most of which will eventually go away when we move towards
using the global parameters via Heat environment files instead.

This patch provides an alternate implementation of
the OS::TripleO::Controller::SoftwareConfig which uses Puppet
to drive the configuration. Using this it is possible
to create a fully functional overcloud controller instance
which has the controller node configured via Puppet
stackforge modules. Initially this includes only the
following services:
MySQL
RabbitMQ
Keepalived/HAProxy (HA is not yet fully supported however)
Nova
Neutron
Keystone
Glance (file backend)
Cinder
Using these services it is possible to run devtest_overcloud.sh
to completion. The idea is that we can quickly add more
services once we have CI in place.
In order to test this you'll want to build your images
with these elements:
os-net-config
heat-config-puppet
puppet-modules
hiera
None of the OpenStack specific TripleO elements
should be used with this approach (the nova/neutron
elements were NOT used to build the controller image).
Also, rather than use neutron-openvswitch-agent to configure
low level networking it is recommended that os-net-config
by configured directly via heat modeling rather than
parameter passing to init-neutron-ovs. This allows us to
configure the physical network while avoiding the coupling to
the neutron-openvswitch-element that our standard
parameter driven networking currently uses. (We still need
to move init-neutron-ovs so that it isn't coupled and/or deprecate
its use entirely because the heat drive stuff is more flexible.)
Packages may optionally be pre-installed via DIB using the
-p option (-p openstack-neutron,openstack-nova) etc.

This patch provides an alternate implementation of
the OS::TripleO::Compute::SoftwareConfig which uses Puppet
to drive the configuration. Using this it is possible
to create a fully functional overcloud compute instance
which has the compute node configured via Puppet
stackforge modules. This includes all the Nova, Neutron,
and Ceilometer configuration required to make things work.
In order to test this you'll want to build your images
with these elements:
os-net-config
heat-config-puppet
puppet-modules
hiera

should be used with this approach (the nova/neutron/ceilometer
