Ironic-Python-Agent (agent)
|
|

---------------------------
|
|
||||||
|
|
||||||
Ironic-Python-Agent is an agent that handles *ironic* bare metal
|
|
||||||
nodes in various actions such as inspection and deployment of such
|
|
||||||
nodes, and runs processes inside of a ramdisk.
|
|
||||||

Boot interfaces
|

|
===============
|

|
|
||||||
|
The boot interface manages booting of both the deploy ramdisk and the user
|
||||||
|
instances on the bare metal node.
|
||||||
|
|
||||||
|
The `PXE boot`_ interface is generic and works with all hardware that supports
|
||||||
|
booting from network. Alternatively, several vendors provide *virtual media*
|
||||||
|
implementations of the boot interface. They work by pushing an ISO image to
|
||||||
|
the node's `management controller`_, and do not require either PXE or iPXE.
|
||||||
|
Check your driver documentation at :doc:`../drivers` for details.
|
||||||
|
|
||||||
|
.. _pxe-boot:
|
||||||
|
|
||||||
|
PXE boot
|
||||||
|
--------
|
||||||
|
|
||||||
|
The ``pxe`` boot interface uses PXE_ or iPXE_ to deliver the target
|
||||||
|
kernel/ramdisk pair. PXE uses relatively slow and unreliable TFTP protocol
|
||||||
|
for transfer, while iPXE uses HTTP. The downside of iPXE is that it's less
|
||||||
|
common, and usually requires bootstrapping using PXE first.
|
||||||
|
|
||||||
|
The ``pxe`` boot interface works by preparing a PXE/iPXE environment for a
|
||||||
|
node on the file system, then instructing the DHCP provider (for example,
|
||||||
|
the Networking service) to boot the node from it. See
|
||||||
|
:ref:`iscsi-deploy-example` and :ref:`direct-deploy-example` for a better
|
||||||
|
understanding of the whole deployment process.
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
Both PXE and iPXE are configured differently, when UEFI boot is used
|
||||||
|
instead of conventional BIOS boot. This is particularly important for CPU
|
||||||
|
architectures that do not have BIOS support at all.
|
||||||
|
|
||||||
|
The ``pxe`` boot interface is used by default for many hardware types,
|
||||||
|
including ``ipmi``, and for all classic drivers with names starting with
|
||||||
|
``pxe_``. Some hardware types, notably ``ilo`` and ``irmc`` have their
|
||||||
|
specific implementations of the PXE boot interface.
|
||||||
|
|
||||||
|
Additional configuration is required for this boot interface - see
|
||||||
|
:doc:`/install/configure-pxe` for details.

Deploy Interfaces
|
||||||
|
=================
|
||||||
|
|
||||||
|
A *deploy* interface plays a critical role in the provisioning process. It
|
||||||
|
orchestrates the whole deployment and defines how the image gets transferred
|
||||||
|
to the target disk.
|
||||||
|
|
||||||
|
.. _iscsi-deploy:
|
||||||
|
|
||||||
|
iSCSI deploy
|
||||||
|
============
|
||||||
|
|
||||||
|
With ``iscsi`` deploy interface (and also ``oneview-iscsi``, specific to the
|
||||||
|
``oneview`` hardware type) the deploy ramdisk publishes the node's hard drive
|
||||||
|
as an iSCSI_ share. The ironic-conductor then copies the image to this share.
|
||||||
|
See :ref:`iSCSI deploy diagram <iscsi-deploy-example>` for a detailed
|
||||||
|
explanation of how this deploy interface works.
|
||||||
|
|
||||||
|
This interface is used by default, if enabled (see
|
||||||
|
:ref:`enable-hardware-interfaces`). You can specify it explicitly
|
||||||
|
when creating or updating a node::
|
||||||
|
|
||||||
|
openstack baremetal node create --driver ipmi --deploy-interface iscsi
|
||||||
|
openstack baremetal node set <NODE> --deploy-interface iscsi
|
||||||
|
|
||||||
|
The ``iscsi`` deploy interface is also used in all of the *classic drivers*
|
||||||
|
with names starting with ``pxe_`` (except for ``pxe_agent_cimc``)
|
||||||
|
and ``iscsi_``.
|
||||||

||||||

|

|
|
||||||
|
.. _direct-deploy:
|
||||||
|
|
||||||
|
Direct deploy
|
||||||
|
=============
|
||||||
|
|
||||||
|
With ``direct`` deploy interface (and also ``oneview-direct``, specific to the
|
||||||
|
``oneview`` hardware type), the deploy ramdisk fetches the image from an
|
||||||
|
HTTP location. It can be an object storage (swift or RadosGW) temporary URL or
|
||||||
|
a user-provided HTTP URL. The deploy ramdisk then copies the image to the
|
||||||
|
target disk. See :ref:`direct deploy diagram <direct-deploy-example>` for
|
||||||
|
a detailed explanation of how this deploy interface works.
|
||||||
|
|
||||||
|
You can specify this deploy interface when creating or updating a node::
|
||||||
|
|
||||||
|
openstack baremetal node create --driver ipmi --deploy-interface direct
|
||||||
|
openstack baremetal node set <NODE> --deploy-interface direct
|
||||||
|
|
||||||
|
The ``direct`` deploy interface is also used in all *classic drivers*
|
||||||
|
whose names include ``agent``.
|
||||||
|
|
||||||
|
.. note::
|
||||||
|
For historical reasons the ``direct`` deploy interface is sometimes called
|
||||||
|
``agent``, and some *classic drivers* using it are called ``agent_*``.
|
||||||
|
This is because before the Kilo release **ironic-python-agent** used to
|
||||||
|
only support this deploy interface.

Alternatively, several vendors provide *virtual media* implementations of the

boot interface. They work by pushing an ISO image to the node's `management
