Code Issues Proposed changes

Retire Packaging Deb project repos 

This commit is part of a series to retire the Packaging Deb
project. Step 2 is to remove all content from the project
repos, replacing it with a README notification where to find
ongoing work, and how to recover the repo if needed at some
future point (as in
https://docs.openstack.org/infra/manual/drivers.html#retiring-a-project).

Basics
~~~~~~
* Our source code is hosted on `OpenStack GitHub`_, but please do not send pull
requests there.
* Please follow usual OpenStack `Gerrit Workflow`_ to submit a patch.
* Update change log in README.rst on any significant change.
* It goes without saying that any code change should by accompanied by unit
tests.
* Note the branch you're proposing changes to. ``master`` is the current focus
of development, use ``stable/VERSION`` for proposing an urgent fix, where
``VERSION`` is the current stable series. E.g. at the moment of writing the
stable branch is ``stable/1.0``.
* Please file a launchpad_ blueprint for any significant code change and a bug
for any significant bug fix.

Development Environment
~~~~~~~~~~~~~~~~~~~~~~~
First of all, install *tox* utility. It's likely to be in your distribution
repositories under name of ``python-tox``. Alternatively, you can install it
from PyPI.
Next checkout and create environments::
git clone https://github.com/openstack/ironic-inspector.git
cd ironic-inspector
tox
Repeat *tox* command each time you need to run tests. If you don't have Python
interpreter of one of supported versions (currently 2.7 and 3.4), use
``-e`` flag to select only some environments, e.g.
::
tox -e py27
.. note::
Support for Python 3 is highly experimental, stay with Python 2 for the
production environment for now.
.. note::
This command also runs tests for database migrations. By default the sqlite
backend is used. For testing with mysql or postgresql, you need to set up
a db named 'openstack_citest' with user 'openstack_citest' and password
'openstack_citest' on localhost. Use the script
``tools/test_setup.sh`` to set the database up the same way as
done in the OpenStack CI environment.
.. note::
Users of Fedora <= 23 will need to run "sudo dnf --releasever=24 update
python-virtualenv" to run unit tests
To run the functional tests, use::
tox -e func
Once you have added new state or transition into inspection state machine, you
should regenerate :ref:`State machine diagram <state_machine_diagram>` with::
tox -e genstates
Run the service with::
.tox/py27/bin/ironic-inspector --config-file example.conf
Of course you may have to modify ``example.conf`` to match your OpenStack
environment.
You can develop and test **ironic-inspector** using DevStack - see
`Deploying Ironic Inspector with DevStack`_ for the current status.
Deploying Ironic Inspector with DevStack
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
`DevStack <http://docs.openstack.org/developer/devstack/>`_ provides a way to
quickly build a full OpenStack development environment with requested
components. There is a plugin for installing **ironic-inspector** in DevStack.
Installing **ironic-inspector** requires a machine running Ubuntu 14.04 (or
later) or Fedora 23 (or later). Make sure this machine is fully up to date and
has the latest packages installed before beginning this process.
Download DevStack::
git clone https://git.openstack.org/openstack-dev/devstack.git
cd devstack
Create ``local.conf`` file with minimal settings required to
enable both the **ironic** and the **ironic-inspector**. You can start with the
`Example local.conf`_ and extend it as needed.
Example local.conf
------------------
.. literalinclude:: ../../../devstack/example.local.conf
Notes
-----
* Set IRONIC_INSPECTOR_BUILD_RAMDISK to True if you want to build ramdisk.
Default value is False and ramdisk will be downloaded instead of building.
* 1024 MiB of RAM is a minimum required for the default build of IPA based on
CoreOS. If you plan to use another operating system and build IPA with
diskimage-builder 2048 MiB is recommended.
* Network configuration is pretty sensitive, better not to touch it
without deep understanding.
* This configuration disables **horizon**, **heat**, **cinder** and
**tempest**, adjust it if you need these services.
Start the install::
./stack.sh
Usage
-----
After installation is complete, you can source ``openrc`` in your shell, and
then use the OpenStack CLI to manage your DevStack::
source openrc admin demo
Show DevStack screens::
screen -x stack
To exit screen, hit ``CTRL-a d``.
List baremetal nodes::
openstack baremetal node list
Bring the node to manageable state::
openstack baremetal node manage <NodeID>
Inspect the node::
openstack baremetal node inspect <NodeID>
.. note::
The deploy driver used must support the inspect interface. See also the
`Ironic Python Agent
<http://docs.openstack.org/developer/ironic/drivers/ipa.html#ipa>`_.
A node can also be inspected using the following command. However, this will
not affect the provision state of the node::
openstack baremetal introspection start <NodeID>
Check inspection status::
openstack baremetal introspection status <NodeID>
Optionally, get the inspection data::
openstack baremetal introspection data save <NodeID>
Writing a Plugin
~~~~~~~~~~~~~~~~
* **ironic-inspector** allows you to hook code into the data processing chain
after introspection. Inherit ``ProcessingHook`` class defined in
ironic_inspector.plugins.base_ module and overwrite any or both of
the following methods:
``before_processing(introspection_data,**)``
called before any data processing, providing the raw data. Each plugin in
the chain can modify the data, so order in which plugins are loaded
matters here. Returns nothing.
``before_update(introspection_data,node_info,**)``
called after node is found and ports are created, but before data is
updated on a node. Please refer to the docstring for details
and examples.
You can optionally define the following attribute:
``dependencies``
a list of entry point names of the hooks this hook depends on. These
hooks are expected to be enabled before the current hook.
Make your plugin a setuptools entry point under
``ironic_inspector.hooks.processing`` namespace and enable it in the
configuration file (``processing.processing_hooks`` option).
* **ironic-inspector** allows plugins to override the action when node is not
found in node cache. Write a callable with the following signature:
``(introspection_data,**)``
called when node is not found in cache, providing the processed data.
Should return a ``NodeInfo`` class instance.
Make your plugin a setuptools entry point under
``ironic_inspector.hooks.node_not_found`` namespace and enable it in the
configuration file (``processing.node_not_found_hook`` option).
* **ironic-inspector** allows more condition types to be added for
`Introspection Rules`_. Inherit ``RuleConditionPlugin`` class defined in
ironic_inspector.plugins.base_ module and overwrite at least the following
method:
``check(node_info,field,params,**)``
called to check that condition holds for a given field. Field value is
provided as ``field`` argument, ``params`` is a dictionary defined
at the time of condition creation. Returns boolean value.
The following methods and attributes may also be overridden:
``validate(params,**)``
called to validate parameters provided during condition creating.
Default implementation requires keys listed in ``REQUIRED_PARAMS`` (and
only them).
``REQUIRED_PARAMS``
contains set of required parameters used in the default implementation
of ``validate`` method, defaults to ``value`` parameter.
``ALLOW_NONE``
if it's set to ``True``, missing fields will be passed as ``None``
values instead of failing the condition. Defaults to ``False``.
Make your plugin a setuptools entry point under
``ironic_inspector.rules.conditions`` namespace.
* **ironic-inspector** allows more action types to be added for `Introspection
Rules`_. Inherit ``RuleActionPlugin`` class defined in
ironic_inspector.plugins.base_ module and overwrite at least the following
method:
``apply(node_info,params,**)``
called to apply the action.
The following methods and attributes may also be overridden:
``validate(params,**)``
called to validate parameters provided during actions creating.
Default implementation requires keys listed in ``REQUIRED_PARAMS`` (and
only them).
``REQUIRED_PARAMS``
contains set of required parameters used in the default implementation
of ``validate`` method, defaults to no parameters.
Make your plugin a setuptools entry point under
``ironic_inspector.rules.conditions`` namespace.
.. note::
``**`` argument is needed so that we can add optional arguments without
breaking out-of-tree plugins. Please make sure to include and ignore it.

Making changes to the database
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
In order to make a change to the ironic-inspector database you must update the
database models found in ironic_inspector.db_ and then create a migration to
reflect that change.
There are two ways to create a migration which are described below, both of
these generate a new migration file. In this file there is only one function:
* ``upgrade`` - The function to run when
``ironic-inspector-dbsync upgrade`` is run, and should be populated with
code to bring the database up to its new state from the state it was in
after the last migration.
For further information on creating a migration, refer to
`Create a Migration Script`_ from the alembic documentation.
Autogenerate
------------
This is the simplest way to create a migration. Alembic will compare the models
to an up to date database, and then attempt to write a migration based on the
differences. This should generate correct migrations in most cases however
there are some cases when it can not detect some changes and may require
manual modification, see `What does Autogenerate Detect (and what does it not
detect?)`_ from the alembic documentation.
::
ironic-inspector-dbsync upgrade
ironic-inspector-dbsync revision -m "A short description" --autogenerate
Manual
------
This will generate an empty migration file, with the correct revision
information already included. However the upgrade function is left empty
and must be manually populated in order to perform the correct actions on
the database::
ironic-inspector-dbsync revision -m "A short description"

Implementing PXE Filter Drivers
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Background
----------
**inspector** in-band introspection PXE-boots the Ironic Python Agent "live"
image, to inspect the baremetal server. **ironic** also PXE-boots IPA to
perform tasks on a node, such as deploying an image. **ironic** uses
**neutron** to provide DHCP, however **neutron** does not provide DHCP for
unknown MAC addresses so **inspector** has to use its own DHCP/TFTP stack for
discovery and inspection.
When **ironic** and **inspector** are operating in the same L2 network, there
is a potential for the two DHCPs to race, which could result in a node being
deployed by **ironic** being PXE booted by **inspector**.
To prevent DHCP races between the **inspector** DHCP and **ironic** DHCP,
**inspector** has to be able to filter which nodes can get a DHCP lease from
the **inspector** DHCP server. These filters can then be used to prevent
node's enrolled in **ironic** inventory from being PXE-booted unless they are
explicitly moved into the ``inspected`` state.
Filter Interface
----------------
.. py:currentmodule:: ironic_inspector.pxe_filter.interface
The contract between **inspector** and a PXE filter driver is described in the
:class:`FilterDriver` interface. The methods a driver has to implement are:
* :meth:`~FilterDriver.init_filter` called on the service start to initialize
internal driver state
* :meth:`~FilterDriver.sync` called both periodically and when a node starts or
finishes introspection to white or blacklist its ports MAC addresses in the
driver
* :meth:`~FilterDriver.tear_down_filter` called on service exit to reset the
internal driver state
.. py:currentmodule:: ironic_inspector.pxe_filter.base
The driver-specific configuration is suggested to be parsed during
instantiation. There's also a convenience generic interface implementation
:class:`BaseFilter` that provides base locking and initialization
implementation. If required, a driver can opt-out from the periodic
synchronization by overriding the :meth:`~BaseFilter.get_periodic_sync_task`.

Hardware introspection for OpenStack Bare Metal
===============================================
Introduction
============
.. image:: http://governance.openstack.org/badges/ironic-inspector.svg
:target: http://governance.openstack.org/reference/tags/index.html
This is an auxiliary service for discovering hardware properties for a
node managed by `Ironic`_. Hardware introspection or hardware
properties discovery is a process of getting hardware parameters required for
scheduling from a bare metal node, given it's power management credentials
(e.g. IPMI address, user name and password).

Upgrade Guide
-------------
The `release notes <http://docs.openstack.org/releasenotes/ironic-inspector/>`_
should always be read carefully when upgrading the ironic-inspector service.
Starting with the Mitaka series, specific upgrade steps and considerations are
well-documented in the release notes.
Upgrades are only supported one series at a time, or within a series.
Only offline (with downtime) upgrades are currently supported.
When upgrading ironic-inspector, the following steps should always be taken:
* Update ironic-inspector code, without restarting the service yet.
* Stop the ironic-inspector service.
* Run database migrations::
ironic-inspector-dbsync --config-file <PATH-TO-INSPECTOR.CONF> upgrade
* Start the ironic-inspector service.
* Upgrade the ironic-python-agent image used for introspection.
.. note::
There is no implicit upgrade order between ironic and ironic-inspector,
unless the `release notes`_ say otherwise.

Install Guide
=============
Install from PyPI_ (you may want to use virtualenv to isolate your
environment)::
pip install ironic-inspector
Also there is a `DevStack <http://docs.openstack.org/developer/devstack/>`_
plugin for **ironic-inspector** - see :ref:`contributing_link` for the
current status.
Finally, some distributions (e.g. Fedora) provide **ironic-inspector**
packaged, some of them - under its old name *ironic-discoverd*.
There are several projects you can use to set up **ironic-inspector** in
production. `puppet-ironic
<http://git.openstack.org/cgit/openstack/puppet-ironic/>`_ provides Puppet
manifests, while `bifrost <http://docs.openstack.org/developer/bifrost/>`_
provides an Ansible-based standalone installer. Refer to Configuration_
if you plan on installing **ironic-inspector** manually.
.. _PyPI: https://pypi.python.org/pypi/ironic-inspector
.. note::
Please beware of :ref:`possible DNS issues <ubuntu-dns>` when installing
**ironic-inspector** on Ubuntu.
Version Support Matrix
----------------------
**ironic-inspector** currently requires the Bare Metal API version
``1.11`` to be provided by **ironic**. This version is available starting
with the Liberty release of **ironic**.
Here is a mapping between the ironic versions and the supported
ironic-inspector versions. The Standalone column shows which
ironic-inspector versions can be used in standalone mode with each
ironic version. The Inspection Interface column shows which
ironic-inspector versions can be used with the inspection interface in
each version of **ironic**.
============== ============ ====================
Ironic Version Standalone Inspection Interface
============== ============ ====================
Juno 1.0 N/A
Kilo 1.0 - 2.2 1.0 - 1.1
Liberty 1.1 - 2.2.7 2.0 - 2.2.7
Mitaka 2.3 - 3.X 2.3 - 3.X
Newton 3.3 - 4.X 3.3 - 4.X
Ocata+ 5.0 - 5.X 5.0 - 5.X
============== ============ ====================
.. note::
``3.X`` means there are no specific plans to deprecate support for this
ironic version. This does not imply that it will be supported forever.
Configuration
-------------
Copy ``example.conf`` to some permanent place
(e.g. ``/etc/ironic-inspector/inspector.conf``).
Fill in these minimum configuration values:
* The ``keystone_authtoken`` section - credentials to use when checking user
authentication.
* The ``ironic`` section - credentials to use when accessing **ironic**
API.
* ``connection`` in the ``database`` section - SQLAlchemy connection string
for the database.
* ``dnsmasq_interface`` in the ``firewall`` section - interface on which
``dnsmasq`` (or another DHCP service) listens for PXE boot requests
(defaults to ``br-ctlplane`` which is a sane default for **tripleo**-based
installations but is unlikely to work for other cases).
See comments inside `example.conf
<https://github.com/openstack/ironic-inspector/blob/master/example.conf>`_
for other possible configuration options.
.. note::
Configuration file contains a password and thus should be owned by ``root``
and should have access rights like ``0600``.
Here is an example *inspector.conf* (adapted from a gate run)::
[DEFAULT]
debug = false
rootwrap_config = /etc/ironic-inspector/rootwrap.conf
[database]
connection = mysql+pymysql://root:<PASSWORD>@127.0.0.1/ironic_inspector?charset=utf8
[firewall]
dnsmasq_interface = br-ctlplane
[ironic]
os_region = RegionOne
project_name = service
password = <PASSWORD>
username = ironic-inspector
auth_url = http://127.0.0.1/identity
auth_type = password
[keystone_authtoken]
auth_uri = http://127.0.0.1/identity
project_name = service
password = <PASSWORD>
username = ironic-inspector
auth_url = http://127.0.0.1/identity_v2_admin
auth_type = password
[processing]
ramdisk_logs_dir = /var/log/ironic-inspector/ramdisk
store_data = swift
[swift]
os_region = RegionOne
project_name = service
password = <PASSWORD>
username = ironic-inspector
auth_url = http://127.0.0.1/identity
auth_type = password
.. note::
Set ``debug = true`` if you want to see complete logs.
**ironic-inspector** requires root rights for managing ``iptables``. It
gets them by running ``ironic-inspector-rootwrap`` utility with ``sudo``.
To allow it, copy file ``rootwrap.conf`` and directory ``rootwrap.d`` to the
configuration directory (e.g. ``/etc/ironic-inspector/``) and create file
``/etc/sudoers.d/ironic-inspector-rootwrap`` with the following content::
Defaults:stack !requiretty
stack ALL=(root) NOPASSWD: /usr/bin/ironic-inspector-rootwrap /etc/ironic-inspector/rootwrap.conf *
.. DANGER::
Be very careful about typos in ``/etc/sudoers.d/ironic-inspector-rootwrap``
as any typo will break sudo for **ALL** users on the system. Especially,
make sure there is a new line at the end of this file.
.. note::
``rootwrap.conf`` and all files in ``rootwrap.d`` must be writeable
only by root.
.. note::
If you store ``rootwrap.d`` in a different location, make sure to update
the *filters_path* option in ``rootwrap.conf`` to reflect the change.
If your ``rootwrap.conf`` is in a different location, then you need
to update the *rootwrap_config* option in ``ironic-inspector.conf``
to point to that location.
Replace ``stack`` with whatever user you'll be using to run
**ironic-inspector**.
Configuring IPA
~~~~~~~~~~~~~~~
ironic-python-agent_ is a ramdisk developed for **ironic** and support
for **ironic-inspector** was added during the Liberty cycle. This is the
default ramdisk starting with the Mitaka release.
.. note::
You need at least 1.5 GiB of RAM on the machines to use IPA built with
diskimage-builder_ and at least 384 MiB to use the *TinyIPA*.
To build an **ironic-python-agent** ramdisk, do the following:
* Get the new enough version of diskimage-builder_::
sudo pip install -U "diskimage-builder>=1.1.2"
* Build the ramdisk::
disk-image-create ironic-agent fedora -o ironic-agent
.. note::
Replace "fedora" with your distribution of choice.
* Use the resulting files ``ironic-agent.kernel`` and
``ironic-agent.initramfs`` in the following instructions to set PXE or iPXE.
Alternatively, you can download a `prebuilt TinyIPA image
<http://tarballs.openstack.org/ironic-python-agent/tinyipa/files/>`_ or use
the `other builders
<http://docs.openstack.org/developer/ironic-python-agent/#image-builders>`_.
.. _diskimage-builder: https://docs.openstack.org/developer/diskimage-builder/
.. _ironic-python-agent: https://docs.openstack.org/developer/ironic-python-agent/
Configuring PXE
~~~~~~~~~~~~~~~
For the PXE boot environment, you'll need:
* TFTP server running and accessible (see below for using *dnsmasq*).
Ensure ``pxelinux.0`` is present in the TFTP root.
Copy ``ironic-agent.kernel`` and ``ironic-agent.initramfs`` to the TFTP
root as well.
* Next, setup ``$TFTPROOT/pxelinux.cfg/default`` as follows::
default introspect
label introspect
kernel ironic-agent.kernel
append initrd=ironic-agent.initramfs ipa-inspection-callback-url=http://{IP}:5050/v1/continue systemd.journald.forward_to_console=yes
ipappend 3
Replace ``{IP}`` with IP of the machine (do not use loopback interface, it
will be accessed by ramdisk on a booting machine).
.. note::
While ``systemd.journald.forward_to_console=yes`` is not actually
required, it will substantially simplify debugging if something
goes wrong. You can also enable IPA debug logging by appending
``ipa-debug=1``.
IPA is pluggable: you can insert introspection plugins called
*collectors* into it. For example, to enable a very handy ``logs`` collector
(sending ramdisk logs to **ironic-inspector**), modify the ``append``
line in ``$TFTPROOT/pxelinux.cfg/default``::
append initrd=ironic-agent.initramfs ipa-inspection-callback-url=http://{IP}:5050/v1/continue ipa-inspection-collectors=default,logs systemd.journald.forward_to_console=yes
.. note::
You probably want to always keep the ``default`` collector, as it provides
the basic information required for introspection.
* You need PXE boot server (e.g. *dnsmasq*) running on **the same** machine as
**ironic-inspector**. Don't do any firewall configuration:
**ironic-inspector** will handle it for you. In **ironic-inspector**
configuration file set ``dnsmasq_interface`` to the interface your
PXE boot server listens on. Here is an example *dnsmasq.conf*::
port=0
interface={INTERFACE}
bind-interfaces
dhcp-range={DHCP IP RANGE, e.g. 192.168.0.50,192.168.0.150}
enable-tftp
tftp-root={TFTP ROOT, e.g. /tftpboot}
dhcp-boot=pxelinux.0
dhcp-sequential-ip
.. note::
``dhcp-sequential-ip`` is used because otherwise a lot of nodes booting
simultaneously cause conflicts - the same IP address is suggested to
several nodes.
Configuring iPXE
~~~~~~~~~~~~~~~~
iPXE allows better scaling as it primarily uses the HTTP protocol instead of
slow and unreliable TFTP. You still need a TFTP server as a fallback for
nodes not supporting iPXE. To use iPXE, you'll need:
* TFTP server running and accessible (see above for using *dnsmasq*).
Ensure ``undionly.kpxe`` is present in the TFTP root. If any of your nodes
boot with UEFI, you'll also need ``ipxe.efi`` there.
* You also need an HTTP server capable of serving static files.
Copy ``ironic-agent.kernel`` and ``ironic-agent.initramfs`` there.
* Create a file called ``inspector.ipxe`` in the HTTP root (you can name and
place it differently, just don't forget to adjust the *dnsmasq.conf* example
below)::
#!ipxe
:retry_dhcp
dhcp || goto retry_dhcp
:retry_boot
imgfree
kernel --timeout 30000 http://{IP}:8088/ironic-agent.kernel ipa-inspection-callback-url=http://{IP}>:5050/v1/continue systemd.journald.forward_to_console=yes BOOTIF=${mac} initrd=agent.ramdisk || goto retry_boot
initrd --timeout 30000 http://{IP}:8088/ironic-agent.ramdisk || goto retry_boot
boot
.. note::
Older versions of the iPXE ROM tend to misbehave on unreliable network
connection, thus we use the timeout option with retries.
Just like with PXE, you can customize the list of collectors by appending
the ``ipa-inspector-collectors`` kernel option. For example::
ipa-inspection-collectors=default,logs,extra_hardware
* Just as with PXE, you'll need a PXE boot server. The configuration, however,
will be different. Here is an example *dnsmasq.conf*::
port=0
interface={INTERFACE}
bind-interfaces
dhcp-range={DHCP IP RANGE, e.g. 192.168.0.50,192.168.0.150}
enable-tftp
tftp-root={TFTP ROOT, e.g. /tftpboot}
dhcp-sequential-ip
dhcp-match=ipxe,175
dhcp-match=set:efi,option:client-arch,7
dhcp-boot=tag:ipxe,http://{IP}:8088/inspector.ipxe
dhcp-boot=tag:efi,ipxe.efi
dhcp-boot=undionly.kpxe,localhost.localdomain,{IP}
First, we configure the same common parameters as with PXE. Then we define
``ipxe`` and ``efi`` tags. Nodes already supporting iPXE are ordered to
download and execute ``inspector.ipxe``. Nodes without iPXE booted with UEFI
will get ``ipxe.efi`` firmware to execute, while the remaining will get
``undionly.kpxe``.
Managing the **ironic-inspector** Database
------------------------------------------
**ironic-inspector** provides a command line client for managing its
database. This client can be used for upgrading, and downgrading the database
using `alembic <https://alembic.readthedocs.org/>`_ migrations.
If this is your first time running **ironic-inspector** to migrate the
database, simply run:
::
ironic-inspector-dbsync --config-file /etc/ironic-inspector/inspector.conf upgrade
If you have previously run a version of **ironic-inspector** earlier than
2.2.0, the safest thing is to delete the existing SQLite database and run
``upgrade`` as shown above. However, if you want to save the existing
database, to ensure your database will work with the migrations, you'll need to
run an extra step before upgrading the database. You only need to do this the
first time running version 2.2.0 or later.
If you are upgrading from **ironic-inspector** version 2.1.0 or lower:
::
ironic-inspector-dbsync --config-file /etc/ironic-inspector/inspector.conf stamp --revision 578f84f38d
ironic-inspector-dbsync --config-file /etc/ironic-inspector/inspector.conf upgrade
If you are upgrading from a git master install of the **ironic-inspector**
after :ref:`rules <introspection_rules>` were introduced:
::
ironic-inspector-dbsync --config-file /etc/ironic-inspector/inspector.conf stamp --revision d588418040d
ironic-inspector-dbsync --config-file /etc/ironic-inspector/inspector.conf upgrade
Other available commands can be discovered by running::
ironic-inspector-dbsync --help
Running
-------
::
ironic-inspector --config-file /etc/ironic-inspector/inspector.conf
A good starting point for writing your own *systemd* unit should be `one used
in Fedora <http://pkgs.fedoraproject.org/cgit/openstack-ironic-discoverd.git/plain/openstack-ironic-discoverd.service>`_
(note usage of old name).

Error Response
~~~~~~~~~~~~~~
If an error happens during request processing, **Ironic Inspector** returns
a response with an appropriate HTTP code set, e.g. 400 for bad request or
404 when something was not found (usually node in cache or node in ironic).
The following JSON body is returned::
{
"error": {
"message": "Full error message"
}
}
This body may be extended in the future to include details that are more error
specific.
API Versioning
~~~~~~~~~~~~~~
The API supports optional API versioning. You can query for minimum and
maximum API version supported by the server. You can also declare required API
version in your requests, so that the server rejects request of unsupported
version.
.. note::
Versioning was introduced in **Ironic Inspector 2.1.0**.
All versions must be supplied as string in form of ``X.Y``, where ``X`` is a
major version and is always ``1`` for now, ``Y`` is a minor version.
* If ``X-OpenStack-Ironic-Inspector-API-Version`` header is sent with request,
the server will check if it supports this version. HTTP error 406 will be
returned for unsupported API version.
* All HTTP responses contain
``X-OpenStack-Ironic-Inspector-API-Minimum-Version`` and
``X-OpenStack-Ironic-Inspector-API-Maximum-Version`` headers with minimum
and maximum API versions supported by the server.
.. note::
Maximum is server API version used by default.
API Discovery
~~~~~~~~~~~~~
The API supports API discovery. You can query different parts of the API to
discover what other endpoints are avaliable.
* ``GET /`` List API Versions
Response:
* 200 - OK
Response body: JSON dictionary containing a list of ``versions``, each
version contains:
* ``status`` Either CURRENT or SUPPORTED
* ``id`` The version identifier
* ``links`` A list of links to this version endpoint containing:
* ``href`` The URL
* ``rel`` The relationship between the version and the href
* ``GET /v1`` List API v1 resources
Response:
* 200 - OK
Response body: JSON dictionary containing a list of ``resources``, each
resource contains:
* ``name`` The name of this resources
* ``links`` A list of link to this resource containing:
* ``href`` The URL
* ``rel`` The relationship between the resource and the href

Troubleshooting
---------------
Errors when starting introspection
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
* *Invalid provision state "available"*
In Kilo release with *python-ironicclient* 0.5.0 or newer Ironic defaults to
reporting provision state ``AVAILABLE`` for newly enrolled nodes.
**ironic-inspector** will refuse to conduct introspection in this state, as
such nodes are supposed to be used by Nova for scheduling. See :ref:`node
states <node_states>` for instructions on how to put nodes into the correct
state.
Introspection times out
~~~~~~~~~~~~~~~~~~~~~~~
There may be 3 reasons why introspection can time out after some time
(defaulting to 60 minutes, altered by ``timeout`` configuration option):
#. Fatal failure in processing chain before node was found in the local cache.
See `Troubleshooting data processing`_ for the hints.
#. Failure to load the ramdisk on the target node. See `Troubleshooting
PXE boot`_ for the hints.
#. Failure during ramdisk run. See `Troubleshooting ramdisk run`_ for the
hints.
Troubleshooting data processing
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
In this case **ironic-inspector** logs should give a good idea what went wrong.
E.g. for RDO or Fedora the following command will output the full log::
sudo journalctl -u openstack-ironic-inspector
(use ``openstack-ironic-discoverd`` for version < 2.0.0).
.. note::
Service name and specific command might be different for other Linux
distributions (and for old version of **ironic-inspector**).
If ``ramdisk_error`` plugin is enabled and ``ramdisk_logs_dir`` configuration
option is set, **ironic-inspector** will store logs received from the ramdisk
to the ``ramdisk_logs_dir`` directory. This depends, however, on the ramdisk
implementation.
Troubleshooting PXE boot
^^^^^^^^^^^^^^^^^^^^^^^^
PXE booting most often becomes a problem for bare metal environments with
several physical networks. If the hardware vendor provides a remote console
(e.g. iDRAC for DELL), use it to connect to the machine and see what is going
on. You may need to restart introspection.
Another source of information is DHCP and TFTP server logs. Their location
depends on how the servers were installed and run. For RDO or Fedora use::
$ sudo journalctl -u openstack-ironic-inspector-dnsmasq
(use ``openstack-ironic-discoverd-dnsmasq`` for version < 2.0.0).
The last resort is ``tcpdump`` utility. Use something like
::
$ sudo tcpdump -i any port 67 or port 68 or port 69
to watch both DHCP and TFTP traffic going through your machine. Replace
``any`` with a specific network interface to check that DHCP and TFTP
requests really reach it.
If you see node not attempting PXE boot or attempting PXE boot on the wrong
network, reboot the machine into BIOS settings and make sure that only one
relevant NIC is allowed to PXE boot.
If you see node attempting PXE boot using the correct NIC but failing, make
sure that:
#. network switches configuration does not prevent PXE boot requests from
propagating,
#. there is no additional firewall rules preventing access to port 67 on the
machine where *ironic-inspector* and its DHCP server are installed.
If you see node receiving DHCP address and then failing to get kernel and/or
ramdisk or to boot them, make sure that:
#. TFTP server is running and accessible (use ``tftp`` utility to verify),
#. no firewall rules prevent access to TFTP port,
#. DHCP server is correctly set to point to the TFTP server,
#. ``pxelinux.cfg/default`` within TFTP root contains correct reference to the
kernel and ramdisk.
.. note::
If using iPXE instead of PXE, check the HTTP server logs and the iPXE
configuration instead.
Troubleshooting ramdisk run
^^^^^^^^^^^^^^^^^^^^^^^^^^^
First, check if the ramdisk logs were stored locally as described in the
`Troubleshooting data processing`_ section. If not, ensure that the ramdisk
actually booted as described in the `Troubleshooting PXE boot`_ section.
Finally, you can try connecting to the IPA ramdisk. If you have any remote
console access to the machine, you can check the logs as they appear on the
screen. Otherwise, you can rebuild the IPA image with your SSH key to be able
to log into it. Use the `dynamic-login`_ or `devuser`_ element for a DIB-based
build or put an authorized_keys file in ``/usr/share/oem/`` for a CoreOS-based
one.
.. _devuser: http://docs.openstack.org/developer/diskimage-builder/elements/devuser/README.html
.. _dynamic-login: http://docs.openstack.org/developer/diskimage-builder/elements/dynamic-login/README.html
Troubleshooting DNS issues on Ubuntu
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. _ubuntu-dns:
Ubuntu uses local DNS caching, so tries localhost for DNS results first
before calling out to an external DNS server. When DNSmasq is installed and
configured for use with ironic-inspector, it can cause problems by interfering
with the local DNS cache. To fix this issue ensure that ``/etc/resolve.conf``
points to your external DNS servers and not to ``127.0.0.1``.
On Ubuntu 14.04 this can be done by editing your
``/etc/resolvconf/resolv.conf.d/head`` and adding your nameservers there.
This will ensure they will come up first when ``/etc/resolv.conf``
is regenerated.
Running Inspector in a VirtualBox environment
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
By default VirtualBox does not expose a DMI table to the guest. This prevents
ironic-inspector from being able to discover the properties of the a node. In
order to run ironic-inspector on a VirtualBox guest the host must be configured
to expose DMI data inside the guest. To do this run the following command on
the VirtualBox host::
VBoxManage setextradata {NodeName} "VBoxInternal/Devices/pcbios/0/Config/DmiExposeMemoryTable" 1
.. note::
Replace `{NodeName}` with the name of the guest you wish to expose the DMI
table on. This command will need to be run once per host to enable this
functionality.

Usage
-----
.. _usage_guide:
Refer to :ref:`api <http_api>` for information on the HTTP API.
Refer to the `client documentation`_ for information on how to use CLI and
Python library.
.. _client documentation: http://docs.openstack.org/developer/python-ironic-inspector-client
Using from Ironic API
~~~~~~~~~~~~~~~~~~~~~
Ironic Kilo introduced support for hardware introspection under name of
"inspection". **ironic-inspector** introspection is supported for some generic
drivers, please refer to `Ironic inspection documentation`_ for details.
.. _Ironic inspection documentation: http://docs.openstack.org/developer/ironic/deploy/inspection.html
Node States
~~~~~~~~~~~
.. _node_states:
* The nodes should be moved to ``MANAGEABLE`` provision state before
introspection (requires *python-ironicclient* of version 0.5.0 or newer)::
ironic node-set-provision-state <UUID> manage
* After successful introspection and before deploying nodes should be made
available to Nova, by moving them to ``AVAILABLE`` state::
ironic node-set-provision-state <UUID> provide
.. note::
Due to how Nova interacts with Ironic driver, you should wait 1 minute
before Nova becomes aware of available nodes after issuing this command.
Use ``nova hypervisor-stats`` command output to check it.
Introspection Rules
~~~~~~~~~~~~~~~~~~~
.. _introspection_rules:
Inspector supports a simple JSON-based DSL to define rules to run during
introspection. Inspector provides an API to manage such rules, and will run
them automatically after running all processing hooks.
A rule consists of conditions to check, and actions to run. If conditions
evaluate to true on the introspection data, then actions are run on a node.
Available conditions and actions are defined by plugins, and can be extended,
see :ref:`contributing_link` for details. See :ref:`api <http_api>` for
specific calls to define introspection rules.
Conditions
^^^^^^^^^^
A condition is represented by an object with fields:
``op`` the type of comparison operation, default available operators include:
* ``eq``, ``le``, ``ge``, ``ne``, ``lt``, ``gt`` - basic comparison operators;
* ``in-net`` - checks that an IP address is in a given network;
* ``matches`` - requires a full match against a given regular expression;
* ``contains`` - requires a value to contain a given regular expression;
* ``is-empty`` - checks that field is an empty string, list, dict or
None value.
``field`` a `JSON path <http://goessner.net/articles/JsonPath/>`_ to the field
in the introspection data to use in comparison.
Starting with the Mitaka release, you can also apply conditions to ironic node
field. Prefix field with schema (``data://`` or ``node://``) to distinguish
between values from introspection data and node. Both schemes use JSON path::
{"field": "node://property.path", "op": "eq", "value": "val"}
{"field": "data://introspection.path", "op": "eq", "value": "val"}
if scheme (node or data) is missing, condition compares data with
introspection data.
``invert`` boolean value, whether to invert the result of the comparison.
``multiple`` how to treat situations where the ``field`` query returns multiple
results (e.g. the field contains a list), available options are:
* ``any`` (the default) require any to match,
* ``all`` require all to match,
* ``first`` requrie the first to match.
All other fields are passed to the condition plugin, e.g. numeric comparison
operations require a ``value`` field to compare against.
Actions
^^^^^^^
An action is represented by an object with fields:
``action`` type of action. Possible values are defined by plugins.
All other fields are passed to the action plugin.
Default available actions include:
* ``fail`` fail introspection. Requires a ``message`` parameter for the failure
message.
* ``set-attribute`` sets an attribute on an Ironic node. Requires a ``path``
field, which is the path to the attribute as used by ironic (e.g.
``/properties/something``), and a ``value`` to set.
* ``set-capability`` sets a capability on an Ironic node. Requires ``name``
and ``value`` fields, which are the name and the value for a new capability
accordingly. Existing value for this same capability is replaced.
* ``extend-attribute`` the same as ``set-attribute``, but treats existing
value as a list and appends value to it. If optional ``unique`` parameter is
set to ``True``, nothing will be added if given value is already in a list.
Starting from Mitaka release, ``value`` field in actions supports fetching data
from introspection, it's using `python string formatting notation
<https://docs.python.org/2/library/string.html#formatspec>`_ ::
{"action": "set-attribute", "path": "/driver_info/ipmi_address",
"value": "{data[inventory][bmc_address]}"}
Plugins
~~~~~~~
.. _introspection_plugins:
**ironic-inspector** heavily relies on plugins for data processing. Even the
standard functionality is largely based on plugins. Set ``processing_hooks``
option in the configuration file to change the set of plugins to be run on
introspection data. Note that order does matter in this option, especially
for hooks that have dependencies on other hooks.
These are plugins that are enabled by default and should not be disabled,
unless you understand what you're doing:
``scheduler``
validates and updates basic hardware scheduling properties: CPU number and
architecture, memory and disk size.
.. note::
Diskless nodes have the disk size property ``local_gb == 0``. Always use
node driver ``root_device`` hints to prevent unexpected HW failures
passing silently.
``validate_interfaces`` validates network interfaces information. Creates new
ports, optionally deletes ports that were not present in the introspection
data. Also sets the ``pxe_enabled`` flag for the PXE-booting port and
unsets it for all the other ports to avoid **nova** picking a random port
to boot the node.
The following plugins are enabled by default, but can be disabled if not
needed:
``ramdisk_error``
reports error, if ``error`` field is set by the ramdisk, also optionally
stores logs from ``logs`` field, see :ref:`api <http_api>` for details.
``capabilities``
detect node capabilities: CPU, boot mode, etc. See `Capabilities
Detection`_ for more details.
``pci_devices``
gathers the list of all PCI devices returned by the ramdisk and compares to
those defined in ``alias`` field(s) from ``pci_devices`` section of
configuration file. The recognized PCI devices and their count are then
stored in node properties. This information can be later used in nova
flavors for node scheduling.
Here are some plugins that can be additionally enabled:
``example``
example plugin logging it's input and output.
``raid_device``
gathers block devices from ramdisk and exposes root device in multiple
runs.
``extra_hardware``
stores the value of the 'data' key returned by the ramdisk as a JSON
encoded string in a Swift object. The plugin will also attempt to convert
the data into a format usable by introspection rules. If this is successful
then the new format will be stored in the 'extra' key. The 'data' key is
then deleted from the introspection data, as unless converted it's assumed
unusable by introspection rules.
``local_link_connection``
Processes LLDP data returned from inspection specifically looking for the
port ID and chassis ID, if found it configures the local link connection
information on the nodes Ironic ports with that data. To enable LLDP in the
inventory from IPA ``ipa-collect-lldp=1`` should be passed as a kernel
parameter to the IPA ramdisk. In order to avoid processing the raw LLDP
data twice, the ``lldp_basic`` plugin should also be installed and run
prior to this plugin.
``lldp_basic``
Processes LLDP data returned from inspection and parses TLVs from the
Basic Management (802.1AB), 802.1Q, and 802.3 sets and stores the
processed data back to the Ironic inspector data in Swift.
Refer to :ref:`contributing_link` for information on how to write your
own plugin.
Discovery
~~~~~~~~~
Starting from Mitaka, **ironic-inspector** is able to register new nodes
in Ironic.
The existing ``node-not-found-hook`` handles what happens if
**ironic-inspector** receives inspection data from a node it can not identify.
This can happen if a node is manually booted without registering it with
Ironic first.
For discovery, the configuration file option ``node_not_found_hook`` should be
set to load the hook called ``enroll``. This hook will enroll the unidentified
node into Ironic using the ``fake`` driver (this driver is a configurable
option, set ``enroll_node_driver`` in the **ironic-inspector** configuration
file, to the Ironic driver you want).
The ``enroll`` hook will also set the ``ipmi_address`` property on the new
node, if its available in the introspection data we received,
see :ref:`ramdisk_callback <ramdisk_callback>`.
Once the ``enroll`` hook is finished, **ironic-inspector** will process the
introspection data in the same way it would for an identified node. It runs
the processing :ref:`plugins <introspection_plugins>`, and after that it runs
introspection rules, which would allow for more customisable node
configuration, see :ref:`rules <introspection_rules>`.
A rule to set a node's Ironic driver to the ``agent_ipmitool`` driver and
populate the required driver_info for that driver would look like::
[{
"description": "Set IPMI driver_info if no credentials",
"actions": [
{"action": "set-attribute", "path": "driver", "value": "agent_ipmitool"},
{"action": "set-attribute", "path": "driver_info/ipmi_username",
"value": "username"},
{"action": "set-attribute", "path": "driver_info/ipmi_password",
"value": "password"}
],
"conditions": [
{"op": "is-empty", "field": "node://driver_info.ipmi_password"},
{"op": "is-empty", "field": "node://driver_info.ipmi_username"}
]
},{
"description": "Set deploy info if not already set on node",
"actions": [
{"action": "set-attribute", "path": "driver_info/deploy_kernel",
"value": "<glance uuid>"},
{"action": "set-attribute", "path": "driver_info/deploy_ramdisk",
"value": "<glance uuid>"}
],
"conditions": [
{"op": "is-empty", "field": "node://driver_info.deploy_ramdisk"},
{"op": "is-empty", "field": "node://driver_info.deploy_kernel"}
]
}]
All nodes discovered and enrolled via the ``enroll`` hook, will contain an
``auto_discovered`` flag in the introspection data, this flag makes it
possible to distinguish between manually enrolled nodes and auto-discovered
nodes in the introspection rules using the rule condition ``eq``::
{
"description": "Enroll auto-discovered nodes with fake driver",
"actions": [
{"action": "set-attribute", "path": "driver", "value": "fake"}
],
"conditions": [
{"op": "eq", "field": "data://auto_discovered", "value": true}
]
}
Reapplying introspection on stored data
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
To allow correcting mistakes in introspection rules the API provides
an entry point that triggers the introspection over stored data. The
data to use for processing is kept in Swift separately from the data
already processed. Reapplying introspection overwrites processed data
in the store. Updating the introspection data through the endpoint
isn't supported yet. Following preconditions are checked before
reapplying introspection:
* no data is being sent along with the request
* Swift store is configured and enabled
* introspection data is stored in Swift for the node UUID
* node record is kept in database for the UUID
* introspection is not ongoing for the node UUID
Should the preconditions fail an immediate response is given to the
user:
* ``400`` if the request contained data or in case Swift store is not
enabled in configuration
* ``404`` in case Ironic doesn't keep track of the node UUID
* ``409`` if an introspection is already ongoing for the node
If the preconditions are met a background task is executed to carry
out the processing and a ``202 Accepted`` response is returned to the
endpoint user. As requested, these steps are performed in the
background task:
* preprocessing hooks
* post processing hooks, storing result in Swift
* introspection rules
These steps are avoided, based on the feature requirements:
* ``node_not_found_hook`` is skipped
* power operations
* roll-back actions done by hooks
Limitations:
* there's no way to update the unprocessed data atm.
* the unprocessed data is never cleaned from the store
* check for stored data presence is performed in background;
missing data situation still results in a ``202`` response
Capabilities Detection
~~~~~~~~~~~~~~~~~~~~~~
Starting with the Newton release, **Ironic Inspector** can optionally discover
several node capabilities. A recent (Newton or newer) IPA image is required
for it to work.
Boot mode
^^^^^^^^^
The current boot mode (BIOS or UEFI) can be detected and recorded as
``boot_mode`` capability in Ironic. It will make some drivers to change their
behaviour to account for this capability. Set the ``[capabilities]boot_mode``
configuration option to ``True`` to enable.
CPU capabilities
^^^^^^^^^^^^^^^^
Several CPU flags are detected by default and recorded as following
capabilities:
* ``cpu_aes`` AES instructions.
* ``cpu_vt`` virtualization support.
* ``cpu_txt`` TXT support.
* ``cpu_hugepages`` huge pages (2 MiB) support.
* ``cpu_hugepages_1g`` huge pages (1 GiB) support.
It is possible to define your own rules for detecting CPU capabilities.
Set the ``[capabilities]cpu_flags`` configuration option to a mapping between
a CPU flag and a capability, for example::
cpu_flags = aes:cpu_aes,svm:cpu_vt,vmx:cpu_vt
See the default value of this option for a more detail example.
InfiniBand support
^^^^^^^^^^^^^^^^^^
Starting with the Ocata release, **Ironic Inspector** supports detection of
InfiniBand network interfaces. A recent (Ocata or newer) IPA image is required
for that to work. When an InfiniBand network interface is discovered, the
**Ironic Inspector** adds a ``client-id`` attribute to the ``extra`` attribute
in the ironic port. The **Ironic Inspector** should be configured with
``firewall.ethoib_interfaces`` to indicate the Ethernet Over InfiniBand (EoIB)
which are used for physical access access to the DHCP network.
For example if **Ironic Inspector** DHCP server is using ``br-inspector`` and
the ``br-inspector`` has EoIB port e.g. ``eth0``,
the ``firewall.ethoib_interfaces`` should be set to ``eth0``.
The ``firewall.ethoib_interfaces`` allows to map the baremetal GUID to it's
EoIB MAC based on the neighs files. This is needed for blocking DHCP traffic
of the nodes (MACs) which are not part of the introspection.
The format of the ``/sys/class/net/<ethoib>/eth/neighs`` file::
# EMAC=<ethernet mac of the ethoib> IMAC=<qp number:lid:GUID>
# For example:
IMAC=97:fe:80:00:00:00:00:00:00:7c:fe:90:03:00:29:26:52
qp number=97:fe
lid=80:00:00:00:00:00:00
GUID=7c:fe:90:03:00:29:26:52
Example of content::
EMAC=02:00:02:97:00:01 IMAC=97:fe:80:00:00:00:00:00:00:7c:fe:90:03:00:29:26:52
EMAC=02:00:00:61:00:02 IMAC=61:fe:80:00:00:00:00:00:00:7c:fe:90:03:00:29:24:4f

How Ironic Inspector Works
==========================
Workflow
--------
Usual hardware introspection flow is as follows:
* Operator enrolls nodes into Ironic_ e.g. via ironic CLI command.
Power management credentials should be provided to Ironic at this step.
* Nodes are put in the correct state for introspection as described in
:ref:`node states <node_states>`.
* Operator sends nodes on introspection using **ironic-inspector** API or CLI
(see :ref:`usage <usage_guide>`).
* On receiving node UUID **ironic-inspector**:
* validates node power credentials, current power and provisioning states,
* allows firewall access to PXE boot service for the nodes,
* issues reboot command for the nodes, so that they boot the ramdisk.
* The ramdisk collects the required information and posts it back to
**ironic-inspector**.
* On receiving data from the ramdisk, **ironic-inspector**:
* validates received data,
* finds the node in Ironic database using it's BMC address (MAC address in
case of SSH driver),
* fills missing node properties with received data and creates missing ports.
.. note::
**ironic-inspector** is responsible to create Ironic ports for some or all
NIC's found on the node. **ironic-inspector** is also capable of
deleting ports that should not be present. There are two important
configuration options that affect this behavior: ``add_ports`` and
``keep_ports`` (please refer to ``example.conf`` for detailed explanation).
Default values as of **ironic-inspector** 1.1.0 are ``add_ports=pxe``,
``keep_ports=all``, which means that only one port will be added, which is
associated with NIC the ramdisk PXE booted from. No ports will be deleted.
This setting ensures that deploying on introspected nodes will succeed
despite `Ironic bug 1405131
<https://bugs.launchpad.net/ironic/+bug/1405131>`_.
Ironic inspection feature by default requires different settings:
``add_ports=all``, ``keep_ports=present``, which means that ports will be
created for all detected NIC's, and all other ports will be deleted.
Refer to the `Ironic inspection documentation`_ for details.
Ironic inspector can also be configured to not create any ports. This is
done by setting ``add_ports=disabled``. If setting ``add_ports`` to disabled
the ``keep_ports`` option should be also set to ``all``. This will ensure
no manually added ports will be deleted.
.. _Ironic inspection documentation: http://docs.openstack.org/developer/ironic/deploy/inspection.html
* Separate API (see :ref:`usage <usage_guide>` and :ref:`api <http_api>`) can
be used to query introspection results for a given node.
* Nodes are put in the correct state for deploying as described in
:ref:`node states <node_states>`.
Starting DHCP server and configuring PXE boot environment is not part of this
package and should be done separately.

will delete the temporarily saved block device serials in node.extra.
This way, it helps to figure out the root device hint in cases when
otherwise Ironic doesn't have enough information to do so. Such a usecase
is DRAC RAID configuration where the BMC doesn't provide any useful
information about the created RAID disks. Using this plugin immediately
before and after creating the root RAID device will solve the issue of root
device hints.
In cases where there's no RAID volume on the node, the standard plugin will
fail due to the missing local_gb value. This plugin fakes the missing
value, until it's corrected during later runs. Note, that for this to work
the plugin needs to take precedence over the standard plugin.

`Plugin <http://docs.openstack.org/developer/tempest/plugin.html>`_
The legacy method of running Tempest is to just treat the Tempest source code
as a python unittest:
`Run tests <http://docs.openstack.org/developer/tempest/overview.html#legacy-run-method>`_
There is also tox configuration for tempest, use following regex for running
introspection tests::
$ tox -e all-plugin -- inspector_tempest_plugin
