Michael Davies 55064d99b9 Update ironic config docs for keystone v3
Ironic's installation guide specifies keystone v2 authentication,
which is now deprecated. This patch updates the example to make it
v3 compliant.

Configure Compute to use the Bare Metal service
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
The Compute service needs to be configured to use the Bare Metal service's
driver. The configuration file for the Compute service is typically located at
``/etc/nova/nova.conf``.
.. note::
This configuration file must be modified on the Compute service's
controller nodes and compute nodes.
#. Change these configuration options in the ``default`` section, as follows:
.. code-block:: ini
[default]
# Driver to use for controlling virtualization. Options
# include: libvirt.LibvirtDriver, xenapi.XenAPIDriver,
# fake.FakeDriver, baremetal.BareMetalDriver,
# vmwareapi.VMwareESXDriver, vmwareapi.VMwareVCDriver (string
# value)
#compute_driver=<None>
compute_driver=ironic.IronicDriver
# Firewall driver (defaults to hypervisor specific iptables
# driver) (string value)
#firewall_driver=<None>
firewall_driver=nova.virt.firewall.NoopFirewallDriver
# The scheduler host manager class to use (string value)
#scheduler_host_manager=host_manager
scheduler_host_manager=ironic_host_manager
# Virtual ram to physical ram allocation ratio which affects
# all ram filters. This configuration specifies a global ratio
# for RamFilter. For AggregateRamFilter, it will fall back to
# this configuration value if no per-aggregate setting found.
# (floating point value)
#ram_allocation_ratio=1.5
ram_allocation_ratio=1.0
# Amount of disk in MB to reserve for the host (integer value)
#reserved_host_disk_mb=0
reserved_host_memory_mb=0
# Flag to decide whether to use baremetal_scheduler_default_filters or not.
# (boolean value)
#scheduler_use_baremetal_filters=False
scheduler_use_baremetal_filters=True
# Determines if the Scheduler tracks changes to instances to help with
# its filtering decisions (boolean value)
#scheduler_tracks_instance_changes=True
scheduler_tracks_instance_changes=False
# New instances will be scheduled on a host chosen randomly from a subset
# of the N best hosts, where N is the value set by this option. Valid
# values are 1 or greater. Any value less than one will be treated as 1.
# For ironic, this should be set to a number >= the number of ironic nodes
# to more evenly distribute instances across the nodes.
#scheduler_host_subset_size=1
scheduler_host_subset_size=9999999
#. Change these configuration options in the ``ironic`` section.
Replace:
- ``IRONIC_PASSWORD`` with the password you chose for the ``ironic``
user in the Identity Service
- ``IRONIC_NODE`` with the hostname or IP address of the ironic-api node
- ``IDENTITY_IP`` with the IP of the Identity server
.. code-block:: ini
[ironic]
# Ironic authentication type
auth_type=password
# Keystone API endpoint
auth_url=http://IDENTITY_IP:35357/v3
# Ironic keystone project name
project_name=service
# Ironic keystone admin name
username=ironic
# Ironic keystone admin password
password=IRONIC_PASSWORD
# Ironic keystone project domain
# or set project_domain_id
project_domain_name=Default
# Ironic keystone user domain
# or set user_domain_id
user_domain_name=Default
#. On the Compute service's controller nodes, restart the ``nova-scheduler``
process:
.. code-block:: console
Fedora/RHEL7/CentOS7:
sudo systemctl restart openstack-nova-scheduler
Ubuntu:
sudo service nova-scheduler restart
#. On the Compute service's compute nodes, restart the ``nova-compute``
process:
.. code-block:: console
Fedora/RHEL7/CentOS7:
sudo systemctl restart openstack-nova-compute
Ubuntu:
sudo service nova-compute restart
