This commit updates links affected by doc migration. Note that other links are not touched in this commit. Fixing other broken links or changing http to https should be covered by a separate patch. Also convert http links to docs.openstack.org to https per reviewer request (though it is not directly related to doc-migration). Note that this commit does not touch files under releasenotes/notes/. If we touch release notes in older releases, reno will considers it as a release note in the current release. (Pike release notes are clean up in a separate patch.)

Release Overview
|
|
================
|
|
|
|
The Icehouse release cycle brings several improvements to Horizon's
|
|
user experience, improved extensibility, and support for many
|
|
additional features in existing projects. The community continues to
|
|
grow. Read more for the specifics.
|

Highlights
|
|
==========
|
|
|
|
New Features
|
|
------------
|
|
|
|
Nova
|
|
~~~~
|
|
|
|
The number of OpenStack Compute (Nova) features that are supported in Icehouse
|
|
grew. New features in the Icehouse release include:
|
|
|
|
* Live Migration Support
|
|
* HyperV Console Support
|
|
* Disk config extension support
|
|
* Improved support for managing host aggregates and availability zones
|
|
* Support for easily setting flavor extra specs
|
|
|
|
Cinder
|
|
~~~~~~
|
|
|
|
In an ongoing effort to implement Role Based Access Support throughout Horizon,
|
|
access controls were added in the OpenStack Volume (Cinder) related panels.
|
|
Utilization of the Cinder v2 API is now a supported option in the Icehouse
|
|
release. The ability to extend volumes is now available as well.
|
|
|
|
Neutron
|
|
~~~~~~~
|
|
|
|
Display of Router Rules for routers where they are defined is now supported in
|
|
Horizon.
|
|
|
|
Swift
|
|
~~~~~
|
|
|
|
With Icehouse, the ability for users to create containers and mark them as
|
|
public is now available. Links are added to download these public containers.
|
|
Users can now explicitly create pseudo directories rather than being required to
|
|
create them as part of the container creation process.
|
|
|
|
Heat
|
|
~~~~
|
|
|
|
In Icehouse, Horizon delivers support for updating existing Heat stacks.
|
|
Now stacks that have already been deployed can be adjusted and redeployed. The
|
|
updated template is also validated when updated. Additionally, support for
|
|
adding environment files was included.
|
|
|
|
Ceilometer
|
|
~~~~~~~~~~
|
|
|
|
Horizon has added support for administrators to query Ceilometer and
|
|
view a daily usage report per project across services through the
|
|
OpenStack Dashboard to better understand how system resources are being
|
|
consumed by individual projects.
|
|
|
|
Trove Databases
|
|
~~~~~~~~~~~~~~~
|
|
|
|
The OpenStack Database as a Service project (Trove) is part of the
|
|
integrated release in the Icehouse cycle. Improvements to the client
|
|
connections and overall stability were added in the Icehouse cycle.
|
|
|
|
|
|
User Experience Improvements
|
|
----------------------------
|
|
|
|
Extensible Enhancements
|
|
~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The primary dashboard and panel navigation has been updated from the tab
|
|
navigation to an accordion implementation. Dashboards and Panel Groups are now
|
|
expandable and collapsible in the page navigation. This change allows for the
|
|
addition of more dashboards as well as accommodates the increasing number of
|
|
panels in dashboards.
|
|
|
|
Wizard
|
|
~~~~~~
|
|
|
|
Horizon now provides a Wizard control to complete multi-step interdependent
|
|
tasks. This is now utilized in the create network action.
|
|
|
|
Inline Table Editing
|
|
~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Tables can now be written to support editing fields in the table to reduce the
|
|
need for opening separate forms. The first sample of this is in the Admin
|
|
dashboard, Projects panel.
|
|
|
|
Self-Service Password Change
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Leveraging enhancements to Identity API v3 (Keystone), users can now change
|
|
their own passwords without the need to involve an administrator. This
|
|
functionality was previously only available with Identity API v2.0.
|
|
|
|
Server Side Table Filtering
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Tables can now easily be wired to filter results from underlying API calls
|
|
based on criteria selected by the user rather than just perform an on page
|
|
search. The first example of this is in the Admin dashboard, Instances panel.
|
|
|
|
Under The Hood
|
|
--------------
|
|
|
|
JavaScript
|
|
~~~~~~~~~~
|
|
|
|
In a move to provide a better user experience, Horizon has adopted AngularJS as
|
|
the primary JavaScript framework. JavaScript is now a browser requirement to
|
|
run the Horizon interface. More to come in Juno.
|
|
|
|
Plugin Architecture
|
|
~~~~~~~~~~~~~~~~~~~
|
|
|
|
Horizon now boasts dynamic loading/disabling of dashboards, panel groups and
|
|
panels. By merely adding a file in the ``enabled`` directory, the selection of
|
|
items loaded into Horizon can be altered. Editing the Django settings file is
|
|
no longer required.
|
|
|
|
For more information see
|
|
`Pluggable Settings <https://docs.openstack.org/horizon/latest/configuration/pluggable_panels.html>`__.
|
|
|
|
Integration Test Framework
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
Horizon now supports running integration tests against a working devstack
|
|
system. There is a limited test suite, but this a great step forward and allows
|
|
full integration testing.
|
|
|
|
Django 1.6 Support
|
|
~~~~~~~~~~~~~~~~~~
|
|
|
|
Django versions 1.4 - 1.6 are now supported by Horizon.
|
|
|
|
|
|
Upgrade Information
|
|
===================
|
|
|
|
Beginning with the Icehouse cycle, there is now a requirement for JavaScript
|
|
support in browsers used with OpenStack Dashboard.
|
|
|
|
Page Layout Changes
|
|
-------------------
|
|
|
|
The overall structure of the page layout in Horizon has been altered. Existing
|
|
templates by 3rd parties to override page templates may require some rework.
|
|
|
|
Default Hypervisor Settings Changes
|
|
-----------------------------------
|
|
|
|
The default for ``can_set_password`` is now ``False``. This means that unless
|
|
the setting is explicitly set to ``True``, the option to set an
|
|
'Admin password' for an instance will not be shown in the Launch Instance
|
|
workflow. Not all hypervisors support this feature which created confusion with
|
|
users.
|
|
|
|
The default for ``can_set_mountpoint`` is now ``False``, and should be set to
|
|
``True`` in the settings in order to add the option to set the mount point for
|
|
volumes in the dashboard. At this point only the Xen hypervisor supports this
|
|
feature.
|
|
|
|
To change the behavior around hypervisor management in Horizon you must add the
|
|
``OPENSTACK_HYPERVISOR_FEATURES`` setting to your ``settings.py`` or
|
|
``local_settings.py`` file.
|
|
|
|
For more information see
|
|
`OPENSTACK_HYPERVISOR_FEATURES setting <https://docs.openstack.org/horizon/latest/configuration/settings.html#openstack-hypervisor-features>`__.

|
|
Known Issues and Limitations
|
|
============================
|
|
|
|
Multi-Domain Cross Service Support
|
|
----------------------------------
|
|
|
|
While Horizon supports managing Identity v3 entities and authenticating in a
|
|
multi-domain Keystone configuration, there is a v3, v2.0 token compatibility
|
|
issue when trying to manage resources for users outside the ``default``
|
|
domain. For this reason, v2.0 has been restored as the default API version
|
|
for OpenStack Identity (Keystone). For a single domain environment, Keystone
|
|
v3 API can still be used via the ``OPENSTACK_API_VERSION`` setting.
