We are looking to provision ironic services in our existing IceHouse implementation, which has all of the various resources on separate computing entities (keystone, glance, nova scheduler, nova compute, cinder, neutron).
Before we make changes to our existing infrastructure, in reading the documentation here: http://docs.openstack.org/developer/ironic/deploy/install-guide.html (http://docs.openstack.org/developer/i...) We have a few questions. In the section entitled “Configure Compute Service to use the Bare Metal Service”, we see that after we’ve setup the database and the ironic bare metal services, we need to reconfigure the Nova Manager and Compute Nodes. Our questions are:

  1. Will this change affect the operation of existing services in our existing openstack setup?

  2. Do we need to make these changes to all of the Nova compute nodes?

  3. Could we just setup one or 2 nodes to act as ironic-conductors?

  4. Does the ironic-conductor run on its own resource, on the nova compute and Manager nodes, or on all 3?

via IRC, <rloo> gave the following answer: To be clear, with the changes to use Ironic, the OpenStack cluster will not be able to provision both VMs and baremetal. so 1. it'll only affect the nova/compute service. 2. yes. but you don't need many compute nodes. or at least, not to try out ironic. 3. well, depends on your load but I'm assuming you just want to try things out. 4. ironic-conductor can run on its own resource,, or you can have it run on compute node. regardless, the ironic code needs to be installed on compute nodes to get the nova-ironic-driver.
