Multi-tenancy in the Bare Metal service
|
|
=======================================
|
|
|
|
Overview
|
|
========
|
|
|
|
It is possible to use dedicated tenant networks for provisioned nodes, which
|
|
extends the current Bare Metal service capabilities of providing flat networks.
|
|
This works in conjunction with the Networking service to allow provisioning of
|
|
nodes in a separate provisioning network. The result of this is that multiple
|
|
tenants can use nodes in an isolated fashion. However, this configuration does
|
|
not support trunk ports belonging to multiple networks.
|
|
|
|
Concepts
|
|
========
|
|
|
|
Network interfaces
|
|
------------------
|
|
|
|
Network interface is one of the driver interfaces that manages network
|
|
switching for nodes. There are 3 network interfaces available in
|
|
the Bare Metal service:
|
|
|
|
- ``noop`` interface is used for standalone deployments, and does not perform
|
|
any network switching;
|
|
|
|
- ``flat`` interface places all provisioned nodes and nodes being deployed into
|
|
a single layer 2 network, separated from the cleaning network;
|
|
|
|
- ``neutron`` interface provides tenant-defined networking by integrating with
|
|
the Networking service, while also separating tenant networks from the
|
|
provisioning and cleaning provider networks.
|
|
|
|
Local link connection
|
|
---------------------
|
|
|
|
The Bare Metal service allows ``local_link_connection`` information to be
|
|
associated with Bare Metal ports. This information is provided to the
|
|
Networking service's ML2 driver when a Virtual Interface (VIF) is attached. The
|
|
ML2 driver uses the information to plug the specified port to the tenant
|
|
network.
|
|
|
|
.. list-table:: ``local_link_connection`` fields
|
|
:header-rows: 1
|
|
|
|
* - Field
|
|
- Description
|
|
* - ``switch_id``
|
|
- Required. Identifies a switch and can be a MAC address or an
|
|
OpenFlow-based ``datapath_id``.
|
|
* - ``port_id``
|
|
- Required. Port ID on the switch, for example, Gig0/1.
|
|
* - ``switch_info``
|
|
- Optional. Used to distinguish different switch models or other
|
|
vendor-specific identifier. Some ML2 plugins may require this
|
|
field.

|
Physical networks
|
|
-----------------
|
|
|
|
A Bare Metal port may be associated with a physical network using its
|
|
``physical_network`` field. The Bare Metal service uses this information when
|
|
mapping between virtual ports in the Networking service and physical ports and
|
|
port groups in the Bare Metal service. A port's physical network field is
|
|
optional, and if not set then any virtual port may be mapped to that port,
|
|
provided that no free Bare Metal port with a suitable physical network
|
|
assignment exists.
|
|
|
|
The physical network of a port group is defined by the physical network of its
|
|
constituent ports. The Bare Metal service ensures that all ports in a port
|
|
group have the same value in their physical network field.
|
|
|
|
When attaching a virtual interface (VIF) to a node, the following ordered
|
|
criteria are used to select a suitable unattached port or port group:
|
|
|
|
* Require ports or port groups to not have a physical network or to have a
|
|
physical network that matches one of the VIF's allowed physical networks.
|
|
* Prefer ports and port groups that have a physical network to ports and
|
|
port groups that do not have a physical network.
|
|
* Prefer port groups to ports. Prefer ports with PXE enabled.
|
|
|
|
Configuring the Bare Metal service
|
|
==================================
|
|
|
|
See the :ref:`configure-tenant-networks` section in the installation guide for
|
|
the Bare Metal service.
|
|
|
|
Configuring nodes
|
|
=================
|
|
|
|
#. Ensure that your python-ironicclient version and requested API version
|
|
are sufficient for your requirements.
|
|
|
|
* Multi-tenancy support was added in API version 1.20, and is supported by
|
|
python-ironicclient version 1.5.0 or higher.
|
|
|
|
* Physical network support for ironic ports was added in API version 1.34,
|
|
and is supported by python-ironicclient version 1.15.0 or higher.
|
|
|
|
The following examples assume you are using python-ironicclient version
|
|
1.15.0 or higher.
|
|
|
|
Export the following variable::
|
|
|
|
export OS_BAREMETAL_API_VERSION=<API version>
|
|
|
|
#. The node's ``network_interface`` field should be set to a valid network
|
|
interface. Valid interfaces are listed in the
|
|
``[DEFAULT]/enabled_network_interfaces`` configuration option in the
|
|
ironic-conductor's configuration file. Set it to ``neutron`` to use the
|
|
Networking service's ML2 driver::
|
|
|
|
openstack baremetal node create --network-interface neutron --driver ipmi
|
|
|
|
.. note::
|
|
If the ``[DEFAULT]/default_network_interface`` configuration option is
|
|
set, the ``--network-interface`` option does not need to be specified
|
|
when creating the node.
|
|
|
|
#. To update an existing node's network interface to ``neutron``, use the
|
|
following commands::
|
|
|
|
openstack baremetal node set $NODE_UUID_OR_NAME \
|
|
--network-interface neutron
|
|
|
|
#. Create a port as follows::
|
|
|
|
openstack baremetal port create $HW_MAC_ADDRESS --node $NODE_UUID \
|
|
--local-link-connection switch_id=$SWITCH_MAC_ADDRESS \
|
|
--local-link-connection switch_info=$SWITCH_HOSTNAME \
|
|
--local-link-connection port_id=$SWITCH_PORT \
|
|
--pxe-enabled true \
|
|
--physical-network physnet1
|
|
|
|
#. Check the port configuration::
|
|
|
|
openstack baremetal port show $PORT_UUID
|
|
|
|
After these steps, the provisioning of the created node will happen in the
|
|
provisioning network, and then the node will be moved to the tenant network
|
|
that was requested.
