HTTP API
|
||||
--------
|
||||
|
||||
By default **ironic-discoverd** listens on ``0.0.0.0:5050``, port
|
||||
can be changed in configuration. Protocol is JSON over HTTP.
|
||||
|
||||
The HTTP API consist of these endpoints:
|
||||
|
||||
Start Introspection
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
``POST /v1/introspection/<UUID>`` initiate hardware introspection for node
|
||||
``<UUID>``. All power management configuration for this node needs to be done
|
||||
prior to calling the endpoint (except when `Setting IPMI Credentials`_).
|
||||
|
||||
Requires X-Auth-Token header with Keystone token for authentication.
|
||||
|
||||
Optional parameters:
|
||||
|
||||
* ``new_ipmi_password`` if set, **ironic-discoverd** will try to set IPMI
|
||||
password on the machine to this value. Power credentials validation will be
|
||||
skipped and manual power on will be required. See `Setting IPMI
|
||||
credentials`_ for details.
|
||||
|
||||
* ``new_ipmi_username`` provides new IPMI user name in addition to password
|
||||
set by ``new_ipmi_password``. Defaults to current ``ipmi_username`` in
|
||||
node ``driver_info`` field.
|
||||

|
||||
* 404 - node cannot be found
|

|
||||
~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
``GET /v1/introspection/<UUID>`` get hardware discovery status.
|
||||
|
||||

|

Ramdisk Callback
|
||||
~~~~~~~~~~~~~~~~
|
||||
|
||||

|
||||
back discovered data. Should not be used for anything other than implementing
|
||||
the ramdisk. Request body: JSON dictionary with at least these keys:
|
||||
|
||||
* ``cpus`` number of CPU
|
||||
* ``cpu_arch`` architecture of the CPU
|
||||
* ``memory_mb`` RAM in MiB
|
||||
* ``local_gb`` hard drive size in GiB
|
||||
* ``interfaces`` dictionary filled with data from all NIC's, keys being
|
||||
interface names, values being dictionaries with keys:
|
||||
|
||||
* ``mac`` MAC address
|
||||
* ``ip`` IP address
|
||||
|
||||
* ``boot_interface`` optional MAC address of the NIC that the machine
|
||||
PXE booted from either in standard format ``11:22:33:44:55:66`` or
|
||||
in *PXELinux* ``BOOTIF`` format ``01-11-22-33-44-55-66``.
|
||||
|
||||
* ``block_devices`` optional block devices information for
|
||||
``root_device_hint`` plugin, dictionary with keys:
|
||||
|
||||
* ``serials`` list of serial numbers of block devices.
|
||||

Installation
|
||||
------------
|
||||
|
||||
**ironic-discoverd** is available as an RPM from Fedora 22 repositories or from
|
||||
Juno RDO_ for Fedora 20, 21 and EPEL 7. It will be installed and preconfigured
|
||||
if you used instack-undercloud_ to build your undercloud.
|
||||
Juno (and later) `RDO <https://www.rdoproject.org/>`_ for Fedora 20, 21
|
||||
and EPEL 7. It will be installed and preconfigured if you used
|
||||
instack-undercloud_ to build your undercloud.
|
||||
Otherwise after enabling required repositories install it using::
|
||||
|
||||
yum install openstack-ironic-discoverd
|
||||
|
||||
To install only Python packages (including the client), use::
|
||||
|
||||
yum install python-ironic-discoverd
|
||||
|
||||
Alternatively (e.g. if you need the latest version), you can install package
|
||||
from PyPI_ (you may want to use virtualenv to isolate your environment)::
|
||||
|
||||
pip install ironic-discoverd
|
||||
|
||||
The third way for RPM-based distros is to use `ironic-discoverd copr`_ which
|
||||
contains **unstable** git snapshots of **ironic-discoverd**.

|
||||
plugin for **ironic-discoverd** - see
|
||||
https://etherpad.openstack.org/p/DiscoverdDevStack for the current status.
|

|
||||
Configuration
|
||||
~~~~~~~~~~~~~
|
||||
|
||||
Copy ``example.conf`` to some permanent place
|
||||
(``/etc/ironic-discoverd/discoverd.conf`` is what is used in the RPM).
|
||||
Fill in at least configuration values with names starting with ``os_`` and
|
||||
``identity_uri``. They configure how **ironic-discoverd** authenticates
|
||||
with Keystone and checks authentication of clients.
|
||||
Fill in at least these configuration values:
|
||||
|
||||
Also set *database* option to where you want **ironic-discoverd** SQLite
|
||||
database to be placed.
|
||||
* ``os_username``, ``os_password``, ``os_tenant_name`` - Keystone credentials
|
||||
to use when accessing other services and check client authentication tokens;
|
||||
|
||||
* ``os_auth_url``, ``identity_uri`` - Keystone endpoints for validating
|
||||
authentication tokens and checking user roles;
|
||||
|
||||
* ``database`` - where you want **ironic-discoverd** SQLite database
|
||||
to be placed;
|
||||
|
||||
* ``dnsmasq_interface`` - 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).
