=====
|
||||
|
||||
This release is a patch release on top of 4.2.0, as part of the stable
|
||||
Liberty series. Full details are available on Launchpad:
|
||||
https://launchpad.net/ironic/liberty/4.2.1.
|
||||
|
||||
* Import Japanese translations - our first major translation addition!
|
||||
|
||||
* Fix a couple of locale issues with deployments, when running on a system
|
||||
using the Japanese locale

.. _V4-2-0:
|
||||
|
||||
4.2.0
|
||||
=====
|
||||
|
||||
This release is proposed as the stable Liberty release for Ironic, and brings
|
||||
with it some bug fixes and small features. Full release details are available
|
||||
on Launchpad: https://launchpad.net/ironic/liberty/4.2.0.
|
||||
|
||||
* Deprecated the bash ramdisk
|
||||
|
||||
The older bash ramdisk built by diskimage-builder is now deprecated and
|
||||
support will be removed at the beginning of the "N" development cycle. Users
|
||||
should migrate to a ramdisk running ironic-python-agent, which now also
|
||||
supports the pxe_* drivers that the bash ramdisk was responsible for.
|
||||
For more info on building an ironic-python-agent ramdisk, see:
|
||||
http://docs.openstack.org/developer/ironic/deploy/install-guide.html#building-or-downloading-a-deploy-ramdisk-image
|
||||
|
||||
* Raised API version to 1.14
|
||||
|
||||
* 1.12 allows setting RAID properties for a node; however support for
|
||||
putting this configuration on a node is not yet implemented for in-tree
|
||||
drivers; this will be added in a future release.
|
||||
|
||||
* 1.13 adds a new 'abort' verb to the provision state API. This may be used
|
||||
to abort cleaning for nodes in the CLEANWAIT state.
|
||||
|
||||
* 1.14 makes the following endpoints discoverable in the API:
|
||||
|
||||
* /v1/nodes/<UUID or logical name>/states
|
||||
|
||||
* /v1/drivers/<driver name>/properties
|
||||
|
||||
* Implemented a new Boot interface for drivers
|
||||
|
||||
This change enhances the driver interface for driver authors, and should not
|
||||
affect users of Ironic, by splitting control of booting a server from the
|
||||
DeployInterface. The BootInterface is responsible for booting an image on a
|
||||
server, while the DeployInterface is responsible for deploying a tenant image
|
||||
to a server.
|
||||
|
||||
This has been implemented in most in-tree drivers, and is a
|
||||
backwards-compatible change for out-of-tree drivers. The following in-tree
|
||||
drivers will be updated in a forth-coming release:
|
||||
|
||||
* agent_ilo
|
||||
|
||||
* agent_irmc
|
||||
|
||||
* iscsi_ilo
|
||||
|
||||
* iscsi_irmc
|
||||
|
||||
* Implemented a new RAID interface for drivers
|
||||
|
||||
This change enhances the driver interface for driver authors. Drivers may
|
||||
begin implementing this interface to support RAID configuration for nodes.
|
||||
This is not yet implemented for any in-tree drivers.
|
||||
|
||||
* Image size is now checked before deployment with agent drivers
|
||||
|
||||
The agent must download the tenant image in full before writing it to disk.
|
||||
As such, the server being deployed must have enough RAM for running the
|
||||
agent and storing the image. This is now checked before Ironic tells the
|
||||
agent to deploy an image. An optional config [agent]memory_consumed_by_agent
|
||||
is provided. When Ironic does this check, this config option may be set to
|
||||
factor in the amount of RAM to reserve for running the agent.
|
||||
|
||||
* Added Cisco IMC driver
|
||||
|
||||
This driver supports managing Cisco UCS C-series servers through the
|
||||
CIMC API, rather than IPMI. Documentation is available at:
|
||||
http://docs.openstack.org/developer/ironic/drivers/cimc.html
|
||||
|
||||
* iLO virtual media drivers can work without Swift
|
||||
|
||||
iLO virtual media drivers (iscsi_ilo and agent_ilo) can work standalone
|
||||
without Swift, by configuring an HTTP(S) server for hosting the
|
||||
deploy/boot images. A web server needs to be running on every conductor
|
||||
node and needs to be configured in ironic.conf.
|
||||
|
||||
iLO driver documentation is available at:
|
||||
http://docs.openstack.org/developer/ironic/drivers/ilo.html
|
||||
|
||||
Known issues
|
||||
~~~~~~~~~~~~
|
||||
|
||||
* Out of tree drivers may be broken by this release. The AgentDeploy and
|
||||
ISCSIDeploy (formerly known as PXEDeploy) classes now depend on drivers to
|
||||
utilize an instance of a BootInterface. For drivers that exist out of tree,
|
||||
that use these deploy classes, an error will be thrown during
|
||||
deployment. There is a simple fix. For drivers that expect these deploy
|
||||
classes to handle PXE booting, one can add the following code to the driver's
|
||||
`__init__` method::
|
||||
|
||||
from ironic.drivers.modules import pxe
|
||||
|
||||
class YourDriver(...):
|
||||
def __init__(self):
|
||||
# ...
|
||||
self.boot = pxe.PXEBoot()
|
||||
|
||||
A driver that handles booting itself (for example, a driver that implements
|
||||
booting from virtual media) should use the following to make calls to the boot
|
||||
interface a no-op::
|
||||
|
||||
from ironic.drivers.modules import fake
|
||||
|
||||
class YourDriver(...)
|
||||
def __init__(self):
|
||||
# ...
|
||||
self.boot = fake.FakeBoot()
|
||||
|
||||
Additionally, as mentioned before, `ironic.drivers.modules.pxe.PXEDeploy`
|
||||
has moved to `ironic.drivers.modules.iscsi_deploy.ISCSIDeploy`, which will
|
||||
break drivers that use this class.
|
||||
|
||||
The Ironic team apologizes profusely for this inconvenience.
|
||||
|
||||
.. _V4-1-0:
|
||||
|
||||
4.1.0
|
||||
=====
|
||||
|
||||
This brings some bug fixes and small features on top of Ironic 4.0.0.
|
||||
Major changes are listed below, and full release details are available
|
||||
on Launchpad: https://launchpad.net/ironic/liberty/4.1.0.
|
||||
|
||||
* Added CORS support
|
||||
|
||||
The Ironic API now has support for CORS requests, that may be used by,
|
||||
for example, web browser-based clients. This is configured in the [cors]
|
||||
section of ironic.conf.
|
||||
|
||||
* Removed deprecated 'admin_api' policy rule
|
||||
|
||||
* Deprecated the 'parallel' option to periodic task decorator
|
||||
|
||||
.. _V4-0-0:
|
||||
|
||||
4.0.0 First semver release
|
||||
============================
|
||||
|
||||
This is the first semver-versioned release of Ironic, created during the
|
||||
OpenStack "Liberty" development cycle. It marks a pivot in our
|
||||
versioning schema from date-based versioning; the previous released
|
||||
version was 2015.1. Full release details are available on Launchpad:
|
||||
https://launchpad.net/ironic/liberty/4.0.0.
|
||||
|
||||
* Raised API version to 1.11
|
||||
|
||||
- v1.7 exposes a new 'clean_step' property on the Node resource.
|
||||
- v1.8 and v1.9 improve query and filter support
|
||||
- v1.10 fixes Node logical names to support all `RFC 3986`_ unreserved
|
||||
characters
|
||||
- v1.11 changes the default state of newly created Nodes from AVAILABLE to
|
||||
ENROLL
|
||||
|
||||
* Support for the new ENROLL workflow during Node creation
|
||||
|
||||
Previously, all Nodes were created in the "available" provision state - before
|
||||
management credentials were validated, hardware was burned in, etc. This could
|
||||
lead to workloads being scheduled to Nodes that were not yet ready for it.
|
||||
|
||||
Beginning with API v1.11, newly created Nodes begin in the ENROLL state,
|
||||
and must be "managed" and "provided" before they are made available for
|
||||
provisioning. API clients must be updated to handle the new workflow when they
|
||||
begin sending the X-OpenStack-Ironic-API-Version header with a value >= 1.11.
|
||||
|
||||
* Migrations from Nova "baremetal" have been removed
|
||||
|
||||
After a deprecation period, the scripts and support for migrating from
|
||||
the old Nova "baremetal" driver to the new Nova "ironic" driver have
|
||||
been removed from Ironic's tree.
|
||||
|
||||
* Removal of deprecated vendor driver methods
|
||||
|
||||
A new @passthru decorator was introduced to the driver API in a previous
|
||||
release. In this release, support for vendor_passthru and
|
||||
driver_vendor_passthru methods has been removed. All in-tree drivers have
|
||||
been updated. Any out of tree drivers which did not update to the
|
||||
@passthru decorator during the previous release will need to do so to be
|
||||
compatible with this release.
|
||||
|
||||
* Introduce new BootInterface to the Driver API
|
||||
|
||||
Drivers may optionally add a new BootInterface. This is merely a
|
||||
refactoring of the Driver API to support future improvements.
|
||||
|
||||
* Several hardware drivers have been added or enhanced
|
||||
|
||||
- Add OCS Driver
|
||||
- Add UCS Driver
|
||||
- Add Wake-On-Lan Power Driver
|
||||
- ipmitool driver supports IPMI v1.5
|
||||
- Add support to SNMP driver for "APC MasterSwitchPlus" series PDU's
|
||||
- pxe_ilo driver now supports UEFI Secure Boot (previous releases of the
|
||||
iLO driver only supported this for agent_ilo and iscsi_ilo)
|
||||
- Add Virtual Media support to iRMC Driver
|
||||
- Add BIOS config to DRAC Driver
|
||||
- PXE drivers now support GRUB2
