Moves legacy documentation from the wiki. Please note, this has stripped out upgrade notes in some links in part because links are broken, and those versions should have long ago exited production, meaning this is largely for contextual information retention by the project. * https://wiki.openstack.org/wiki/ReleaseNotes/Kilo#OpenStack_Bare_Metal_service_.28Ironic.29 * https://wiki.openstack.org/wiki/Ironic/ReleaseNotes/Juno * https://wiki.openstack.org/wiki/Ironic/ReleaseNotes/Icehouse Change-Id: I62016bd6319a612bd0c59f496481cae88a182032

Features
|
|
========
|
|
|
|
State Machine
|
|
-------------
|
|
|
|
* Ironic now uses a formal model for the logical state of each node it manages (New Ironic State Machine). This has enabled the addition of two new processes: cleaning and inspection.
|
|
* Automatic disk erasure between tenants is now enabled by default. This may be extended to perform additional cleaning steps, such as re-applying firmware, resetting BIOS settings, etc (Node Cleaning).
|
|
* Both in-band and out-of-band methods are available to inspect hardware. These methods may be used to update Node properties automatically (Hardware Inspection).
|
|
|
|
Version Headers
|
|
---------------
|
|
|
|
The Ironic REST API expects a new X-OpenStack-Ironic-API-Version header be passed with each HTTP[S] request. This header allows client and server to negotiate a mutually supported interface (REST API "micro" versions). In the absence of this header, the REST service will default to a compatibility mode and yield responses compatible with Juno clients. This mode, however, prevents access to most features introduced in Kilo.
|
|
|
|
Hardware Driver Changes
|
|
=======================
|
|
The following new drivers were added:
|
|
|
|
* AMT
|
|
* iRMC
|
|
* VirtualBox (testing driver only)
|
|
|
|
The following enhancements were made to existing drivers:
|
|
|
|
* Configdrives may be used with the "agent" drivers in lieu of a metadata service, if desired.
|
|
* SeaMicro driver supports serial console
|
|
* iLO driver supports UEFI secure boot
|
|
* iLO driver supports out-of-band node inspection
|
|
* iLO driver supports resetting ilo and bios during cleaning
|
|
|
|
Support for third-party and out-of-tree drivers is enhanced by the following two changes:
|
|
|
|
* Drivers may store their own "internal" information about Nodes.
|
|
* Drivers may register their own periodic tasks to be run by the Conductor.
|
|
* vendor_passthru methods now support additional HTTP methods (eg, PUT and POST).
|
|
* vendor_passthru methods are now discoverable in the REST API. See node vendor passthru and driver vendor passthru
|
|
|
|
Other Changes
|
|
-------------
|
|
|
|
* Logical names may be used to address Nodes, in addition to their canonical UUID.
|
|
* For servers with varied local disks, hints may be supplied that affect which disk device the OS is provisioned to.
|
|
* Support for fetching kernel, ramdisk, and instance images from HTTP[S] sources directly has been added to remove the dependency on Glance. Using ironic as a standalone service
|
|
* Nodes may be placed into maintenance mode via REST API calls. An optional maintenance reason may be specified when doing so.
|
|
|
|
Known Issues
|
|
============
|
|
|
|
* Running more than one nova-compute process is not officially supported.
|
|
* While Ironic does include a ClusteredComputeManager, which allows running more than one nova-compute process with Ironic, it should be considered experimental and has many known problems.
|
|
* Drivers using the "agent" deploy mechanism do not support "rebuild --preserve-ephemeral"
|
|
|
|
Upgrade Notes
|
|
=============
|
|
|
|
* IPMI Passwords are now obfuscated in REST API responses. This may be disabled by changing API policy settings.
|
|
* The "agent" class of drivers now support both whole-disk and partition based images.
|
|
* The driver_info parameters of "pxe_deploy_kernel" and "pxe_deploy_ramdisk" are deprecated in favour of "deploy_kernel" and "deploy_ramdisk".
|
|
* Drivers implementing their own version of the vendor_passthru() method has been deprecated in favour of the new @passthru decorator.
