New charm features
|
||||
------------------
|
||||
|
||||
With each new feature, there is a corresponding example bundle in the form of a
|
||||
test bundle, and/or a `OpenStack Charms Deployment Guide`_ section which
|
||||
details the use of the feature. For example test bundles, see the
|
||||
``src/tests/bundles`` directory within the relevant charm repository.
|
||||

Upgrading charms
|
||||
----------------
|
||||
|
||||
Always use the latest stable charm revision before proceeding with topological
|
||||
changes, charm application migrations, workload upgrades, series upgrades, or
|
||||
bug reports.
|
||||
|
||||
Please ensure that the keystone charm is upgraded first.
|
||||
|
||||
To upgrade an existing deployment to the latest charm version simply use the
|
||||
:command:`upgrade-charm` command. For example:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
juju upgrade-charm keystone
|
||||
|
||||
Charm upgrades and OpenStack upgrades are functionally different. Charm
|
||||
upgrades ensure that the deployment has the latest charm revision, containing
|
||||
the latest charm fixes and features, whereas OpenStack upgrades influence the
|
||||
software package versions of OpenStack itself.
|
||||
|
||||
A charm upgrade does not trigger an OpenStack upgrade. An OpenStack upgrade is
|
||||
a separate process. However, an OpenStack upgrade does require the latest charm
|
||||
revision. Please refer to `OpenStack upgrades`_ in the `OpenStack Charms
|
||||
Deployment Guide`_ for more details.

Known issues
|
||||
------------
|
||||
|
||||
Swift-Proxy and Policy.d overrides
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The is no policy.d override mechanism available for Swift (and, therefore, the
|
||||
swift-proxy charm) as Swift does not use the ``oslo.policy`` library. Swift
|
||||
uses its own authentication system that connects with Keystone and validates
|
||||
according to Swift's own configuration files. The ``operator-roles``
|
||||
configuration option allows the operator to control which Swift operator roles
|
||||
will be authenticated, as usual. See the `Swift Auth System`_ for further
|
||||
details.
|
||||
|
||||
Masakari and Masakari Monitors
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Both Masakari charms remain as previews. Bugs `LP #1728527`_ and `LP #1839715`_
|
||||
need to be resolved in order to arrive at a successful instance HA deployment.
|
||||
Bug `LP #1773765`_ is likely to affect on-going support of a Masakari
|
||||
deployment.
|
||||
|
||||
Glance Simplestreams Sync
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
When deploying the glance-simplestreams-sync charm on Bionic a more recent
|
||||
version of the simplestreams package must be installed by configuring a PPA:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
juju config glance-simplestreams-sync source=ppa:simplestreams-dev/trunk
|
||||
|
||||
See bug `LP #1790904`_ for details.
|
||||
|
||||
Designate and Vault at Ocata and earlier
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The designate charm for OpenStack releases Pike and earlier does not yet
|
||||
support SSL via Vault and the certificates relation. See bug `LP #1839019`_.
|
||||
|
||||
Current versions of OpenStack with Vault and the certificates relation are
|
||||
supported by the Designate charm.
|
||||
|
||||
Restart Nova services after adding certificates relation
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
A race condition exists with the use of the 'certificates' relation. When SSL
|
||||
certificates are issued Nova services may attempt to talk to the placement API
|
||||
over HTTP while the API has already changed to HTTPS. See bug `LP #1826382`_.
|
||||
|
||||
To mitigate against this, restart the nova-compute and nova-scheduler services
|
||||
once certificates have been issued:
|
||||
|
||||
.. code-block:: none
|
||||
|
||||
juju run --application nova-compute "systemctl restart nova-compute"
|
||||
juju run --application nova-cloud-controller "systemctl restart nova-scheduler"
|
||||
|
||||
Bugs fixed
|
||||
----------
|
||||
|
||||
The 20.05 OpenStack Charms release includes NN bug fixes. Refer to the `20.05
|
||||
milestone`_ in Launchpad for the list of resolved bugs.
