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
|
|

|
|
# (boolean value)
|
|

|
|
scheduler_use_baremetal_filters=True

|
|
|
|
# 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
