New Charm Features
|
||||
==================
|
||||
|
||||
OpenStack Ocata support on 16.04
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The charms provide full support for OpenStack Ocata. For further details and
|
||||
documentation on Openstack Ocata please check out
|
||||
http://releases.openstack.org/ocata
|
||||
|
||||
To deploy OpenStack Ocata on Ubuntu 16.04, use the 'openstack-origin'
|
||||
configuration option, for example:
|
||||
|
||||
|
||||
.. code:: bash
|
||||
|
||||
cat > config.yaml << EOF
|
||||
nova-cloud-controller:
|
||||
openstack-origin: cloud:xenial-ocata
|
||||
EOF
|
||||
|
||||
juju deploy --config config.yaml nova-cloud-controller
|
||||
|
||||
To upgrade an existing Mitaka based deployment on Ubuntu 16.04 to the Newton
|
||||
release, simple re-configure the charm with a new openstack-origin
|
||||
configuration:
|
||||
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju config nova-cloud-controller openstack-origin=cloud:xenial-ocata
|
||||
|
||||
Please ensure that ceph services are upgraded before services that consume ceph
|
||||
resources, such as cinder, glance and nova-compute.
|
||||
|
||||
percona-cluster and rabbitmq-server clustering improvements
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
When deploying the percona-cluster or rabbitmq-server charms in clustered
|
||||
configurations, please use the new min-cluster-size configuration option
|
||||
to avoid configuration races during unit deployment and clustering:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju config rabbitmq-server min-cluster-size=3
|
||||
juju add-unit -n 2 rabbitmq-server
|
||||
|
||||
juju config percona-cluster min-cluster-size=3
|
||||
juju add-unit -n 2 percona-cluster
|
||||
|
||||
|
||||
keystone v3 domain independent identity drivers
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The keystone charm now supports use of different identity drivers for v3 domains;
|
||||
the first implementation of this is using the keystone-ldap subordinate charm that
|
||||
provides the ability to use an existing LDAP or Active Directory deployment for
|
||||
authentication of users for a domain. See the keystone-ldap charm for more details.
|
||||
|
||||
hacluster minimum units
|
||||
~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
For this release of the OpenStack Charms, the hacluster charm will default to
|
||||
requiring a minimum of 3 units before cluster formation will occur; this
|
||||
can be switched back to support two unit clusters:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju config hacluster cluster_count=2
|
||||
|
||||
This change reflects the most common use case for hacluster which is for
|
||||
deployments of 3 or more units.
|
||||
|
||||
ceph-osd availability zone support
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ceph-osd charm now supports an availability zone. This can be utilized to
|
||||
modify the default of having 1 replica per host.
|
||||
|
||||
|
||||
Ceph FS support
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
This charm release provides the new ceph-fs charm, providing support for Ceph FS.
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju deploy ceph-fs
|
||||
juju add-relation ceph-mon ceph-fs
|
||||
|
||||
ceph-radosgw keystone v3 support
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The ceph-radosgw charm now has support for the keystone v3 API.
|
||||
|
||||
ceph-radsogw FastCGI support
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
Inline with the Ceph project, the ceph-radosgw charm has dropped support for
|
||||
deployment of the Rados Gateway using Apache and mod_fastcgi; existing deployments
|
||||
will be reconfigured on upgrade to use the embedded webserver support provided
|
||||
by the radosgw binaries.
|
||||
|
||||
|
||||
ceph pool permissions restrictions
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The cinder, cinder-ceph, glance, nova-compute and ceph-radosgw charms can now
|
||||
be optionally configured to request cephx keys with more limited restrictions
|
||||
on pool access as required for OpenStack deployments. This is enabled using the
|
||||
`restrict-ceph-pools` configuration option, for example:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju config cinder-ceph restrict-ceph-pools=True
|
||||
|
||||
Nova LXD block storage support
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
The Nova Compute LXD integration includes support for persistent block device
|
||||
usage via Cinder using the LVM iSCSI driver; this is now enabled by default.
|
||||
|
||||
Upgrading
|
||||
=========
|
||||
|
||||
Please ensure that the keystone charm is upgraded first.
|
||||
|
||||
To upgrade an existing deployment to the latest charm version simply use the
|
||||
'upgrade-charm' command:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju upgrade-charm cinder
|
||||
|
||||
|
||||
Deprecation Notices
|
||||
===================
|
||||
|
||||
ZeroMQ messaging support across the charms will be removed during the Pike
|
||||
development cycle.
|
||||
|
||||
PostgreSQL database support across the charms will be removed during the
|
||||
Pike developement cycle.
|
||||
|
||||
Deploy from Source (DFS) support is under review for sustainability and may be
|
||||
removed during the Pike development cycle.
|
||||
|
||||
Known Issues
|
||||
============
|
||||
|
||||
ceilometer and aodh + Juju 1.25/MAAS 1.9
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
https://bugs.launchpad.net/charms/+source/ceilometer/+bug/1632909
|
||||
|
||||
ceilometer and aodh charms fail to deploy with Juju 1.25 when deployed
|
||||
in LXD containers using the MAAS provider due to hostname resolution
|
||||
issues. Specifically, the API service will fail to startup, resulting
|
||||
in a blocked service status.
|
||||
|
||||
Adding an entry into /etc/hosts on each LXC unit that correctly maps the
|
||||
hostname of the unit to its IP address will workaround this issue.
|
||||
|
||||
Note that this only impacts OpenStack Newton based deployments.
|
||||

||||
