This value is a way for an operator to signal Ironic whether they have an infrastructure for unmanaged inspection. Previously, unmanaged inspection was considered to be always supported. With this change, the inspector-based inspection works as previously, while the new built-in inspection defaults to only managed inspection. Change-Id: I4a9125881dc5822656efde1346807c3dd749973e

Managed and unmanaged inspection
|
|
================================
|
|
|
|
In-band inspection can be *managed* or *unmanaged*. This document explains the
|
|
difference between these two concepts and applies both to the built-in in-band
|
|
inspection and to :doc:`/admin/inspection/inspector`.
|
|
|
|
Managed inspection
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Inspection is *managed* when the Bare Metal conductor fully configures the node
|
|
for inspection, including setting boot device, boot mode and power state. This
|
|
is the only way to conduct inspection using :ref:`redfish-virtual-media` or
|
|
with :doc:`/admin/dhcp-less`. This mode is engaged automatically when the node
|
|
has sufficient information to configure boot (e.g. ports in case of iPXE).
|
|
|
|
There are a few configuration options that tune managed inspection, the most
|
|
important is ``extra_kernel_params``, which allows adding kernel parameters for
|
|
inspection specifically. This is where you can configure
|
|
:ironic-python-agent-doc:`inspection collectors and other parameters
|
|
<admin/how_it_works.html#inspection>`, for example:
|
|
|
|
.. code-block:: ini
|
|
|
|
[inspector]
|
|
extra_kernel_params = ipa-inspection-collectors=default,logs ipa-collect-lldp=1
|
|
|
|
For the callback URL the ironic-inspector endpoint from the service catalog is
|
|
used. If you want to override the endpoint for callback only, set the following
|
|
option:
|
|
|
|
.. code-block:: ini
|
|
|
|
[inspector]
|
|
callback_endpoint_override = https://example.com/baremetal-introspection/v1/continue
|
|
|
|
For the built-in inspection, the bare metal API endpoint can be overriden
|
|
instead:
|
|
|
|
.. code-block:: ini
|
|
|
|
[service_catalog]
|
|
endpoint_override = https://example.com/baremetal
|
|
|
|
.. _unmanaged-inspection:
|
|
|
|
Unmanaged inspection
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Under *unmanaged* inspection we understand in-band inspection where the boot
|
|
configuration (iPXE scripts, DHCP options, etc) is not provided
|
|
by the Bare Metal service. In this case, the node is simply set to boot from
|
|
network and powered on. The operator is responsible for the correct network
|
|
boot configuration, e.g. as explained in :ref:`configure-unmanaged-inspection`.
|
|
|
|
Unmanaged inspection was the only inspection mode before the Ussuri release,
|
|
and it is still used when the node's boot cannot be configured by the
|
|
conductor. The options described above do not affect unmanaged inspection.
|
|
|
|
Because of the complex installation and operation requirements, unmanaged
|
|
inspection is disabled by default. To enable it, set ``require_managed_boot``
|
|
to ``False``:
|
|
|
|
.. code-block:: ini
|
|
|
|
[inspector]
|
|
require_managed_boot = False
