Code Issues Proposed changes

Add HTTP versions of network boot interfaces

Browse Source 
This change adds two network boot interfaces, ``http`` and
``http-ipxe``. These interfaces are based upon the underlying PXE
boot interface code in ironic, and where this differs is it signals
to Ironic that we must do the boot loader needful in terms of telling
DHCP to send a URL instead of a filename and IP address for PXE
as a starting point.

The naming of the interfaces focuses more on the transport mechanism
and then specific style. Very similar to existing ``pxe`` and ``ipxe``
interface modeling, except in the ``ipxe`` case, it is more a specific
loader and mechanism to be utilized.

HTTP Boot
---------
The ``http`` and ``http-ipxe`` boot interfaces are based upon the Ironic
implementation of the ``pxe`` and ``ipxe`` boot interfaces, respectively,
and utilize HTTP in the transmission of the location to start the
boot sequence from. These interfaces are specific to UEFI as they are rooted
in the UEFI standard v2.5's support for booting from an HTTP URL.
One caveat to keep in mind is that these interfaces require hardware support
and the ability to signal to the remote BMC that the node should boot
utilizing ``UEFIHTTP``. If a hardware type does not support that as an option,
we will fallback and request ``PXE`` boot, but that realistically may only
work if the firmware on the machine is smart enough to check and evaluate
for an HTTP Boot URL instead of a PXE boot server and file name.
It should be noted, that these boot interfaces are available for the vendor
independent, generic hardware types of ``ipmi`` and ``redfish``. Hardware
vendors typically only include additional interfaces after they have performed
their own verification and qualification testing.

Configuring PXE and iPXE
Configuring Network Boot
========================
Ironic's primary means of booting hardware to perform actions or work on a
baremetal node is to perform network booting. Traditionally, this has meant
the use of Preboot Execution Environment, or PXE. This support and
and functionality has evolve as time has gone on to include support for not
just the ``pxe`` ``boot_interface`` in concert with hardware vendor specific
variations, but also a distinct ``ipxe`` setting for ``boot_interface`` with
default values to enable use of `iPXE <https://ipxe.org/>`_.
As time passed, ``http`` and ``http-ipxe`` values were also added as valid
``boot_interface`` options which may be used, which are functionally identical
in behavior to ``pxe`` and ``ipxe``, except HTTP is used as the transport
mechanism. Not all hardware supports HTTPBoot, as it is often referred.
.. note::
Support for HTTPBoot interfaces was added during the 2024.1 development
cycle. Prior versions of Ironic does not contain the ``http`` and
``http-ipxe`` boot interfaces.

Finally, put ``ironic-python-agent.kernel`` and
``ironic-python-agent.initramfs`` to ``/httpboot``.
HTTPBoot
--------
HTTPBoot interfaces in Ironic are built upon the underlying network boot
substrate. This means much of the configuration in the ``[pxe]`` and
``[deploy]`` impacts the use of HTTPBoot, except when Ironic is setting
DHCP parameters, it populates a HTTP(S) URL to the DHCP server, which is
then transmitted to the client attempting to Network Boot. In large part,
this is because HTTPBoot is an evolution of PXE Boot technique and
technology.
This means a TFTP server is *not* required, but the HTTP server is
required as if your utilizing iPXE. This is largely because iPXE
has traditionally been leveraged by Operators to limit the TFTP
packets being transmitted via UDP across a network.
One aspect to keep in mind, is HTTPBoot is relatively new when compared
to PXE boot, and not all bootloaders may support HTTPBoot, as the underlying
UEFI standard upon which it was largely based, UEFI v2.5, was published in
2015.
Ironic contains two distinct flavors of HTTPBoot, largely based
upon what configuration defaults are used in terms of boot loader, templates,
and overall mechanism style.
* ``http`` is the boot interface based upon the ``pxe`` boot interface.
This is the interface you would want to use if you had, for example, a
signed GRUB2 bootloader chain to utilize. In this case it is up to the
boot loader to understand how to extract and run with the URL, and then
retrieves any additional configuration loader files and configuration
templates created on disk.
* ``http-ipxe`` is the boot interface based upon the ``ipxe`` boot interface.
This interface signals to the client to utilize the configured iPXE loader
binary over HTTP, and then the boot sequence proceeds with the pattern and
capabilities of iPXE.
To enable the boot interfaces, you will need to add them to your
``[DEFAULT]enabled_boot_interfaces`` configuration entry.

features:
- |
Adds a ``http`` boot interface, based upon the ``pxe`` boot interface
which informs the DHCP server of an HTTP URL to boot the machine from,
and then requests the BMC boot the machine in UEFI HTTP mode.
- |
Adds a ``http-ipxe`` boot interface, based upon the ``ipxe`` boot interface
which informs the DHCP server of an HTTP URL to boot the machine from,
and then requests the BMC boot the machine in UEFI HTTP mode.
issues:
- |
Testing of the ``http`` boot interface with Ubuntu 22.04 provided Grub2
yielded some intermittent failures which appear to be more environmental
in nature as the signed Shim loader would start, then load the GRUB
loader, and then some of the expected files might be attempted to be
accessed, and then fail due to an apparent transfer timeout. Consultation
with some grub developers concur this is likely environmental, meaning
the specific grub build or CI performance related. If you encounter any
issues, please do not hestitate to reach out to the Ironic developer
community.
