New Charm Features
|
||||
==================
|
||||
|
||||
QoS Feature
|
||||
~~~~~~~~~~~
|
||||
|
||||
The Neutron QoS extension driver can now be enabled by setting the 'enable-qos'
|
||||
configuration option in the neutron-api charm. Once this is set neutron rate
|
||||
limiting qos policies can be created and applied to both ports and networks.
|
||||
|
||||
Gnocchi Support
|
||||
~~~~~~~~~~~~~~~
|
||||
|
||||
The OpenStack charms now support deployment of Gnocchi for storage of resources,
|
||||
metrics and associated measures generated by Ceilometer from an OpenStack Cloud.
|
||||
|
||||
This is the first GA/stable release of the Gnocchi charm, following the preview
|
||||
release at 17.08. The charm provides support for use with Ceph for measure
|
||||
storage, with MySQL providing the supporting database infrastructure.
|
||||
|
||||
The gnocchi charm has been officially released and can be deployed via the
|
||||
official charm namespace in the charm store:
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju deploy cs:gnocchi
|
||||
juju deploy cs:memcached
|
||||
juju add-relation gnocchi ceph-mon
|
||||
juju add-relation gnocchi ceilometer
|
||||
juju add-relation gnocchi mysql
|
||||
juju add-relation gnocchi keystone
|
||||
juju add-relation gnocchi memcached
|
||||
|
||||
.. note::
|
||||
|
||||
The Ceilometer API will be automatically disabled as soon as Ceilometer
|
||||
is configured to store cloud telemetry data in Gnocchi.
|
||||
|
||||
.. note::
|
||||
|
||||
The Gnocchi charm only supports deployment of Gnocchi with
|
||||
OpenStack Ocata or later.
|
||||
|
||||
Designate Memcache Backend (Required)
|
||||
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||
The designate charm now supports and requires a memcached back-end. If upgrading
|
||||
the charms on a previous deployment, the designate unit(s) will go into a blocked
|
||||
state until the coordinator-memcached requirement is fulfilled.
|
||||
|
||||
The existing applications will continue to function, but until memcached is deployed
|
||||
and related to designate, the Juju model state will be blocked.
|
||||
|
||||
.. code:: bash
|
||||
|
||||
juju deploy memcached
|
||||
juju add-relation designate memcached
|
||||

||||

|
||||
|
||||
Python 3-Only Run-Time
|
||||
~~~~~~~~~~~~~~~~~~~~~~
|
||||
There is a continued effort to bring the charms into a Py3-only run-time. This
|
||||
effort is intended to be completed for the next stable charms release (18.02).
|
||||
No user or config changes are necessary for charm upgrades or new deployments.
|
||||
|
||||
Reactive charms which are now py3-only:
|
||||
|
||||
* barbican
|
||||
* barbican-softhsm
|
||||
* manila
|
||||
* manila-generic
|
||||
* designate
|
||||
* designate-bind
|
||||
* keystone-ldap
|
||||
* openvswitch-odl
|
||||
* tempest
|
||||
|
||||
Classic charms which are now py3-only:
|
||||
|
||||
* ceph-mon
|
||||
* ceph-osd
|
||||
* heat
|
||||
* neutron-api
|
||||
* neutron-gateway
|
||||
* neutron-openvswitch
|
||||
* nova-compute
|
||||
|
||||
Classic charms which are still using py2 at run-time:
|
||||
|
||||
* swift-proxy
|
||||
* keystone
|
||||
* ceilometer
|
||||
* glance
|
||||
* cinder
|
||||
* nova-cloud-controller
|
||||
|
||||
Libraries with py2/py3 support:
|
||||
|
||||
* charm-helpers
|
||||
* charms.ceph
|
||||
|
||||
Libraries with py3 only support:
|
||||
|
||||
* charms.openstack
|
||||
|
||||
Upgrading charms
|
||||
================
|
||||
|
||||
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 keystone
|
||||
|
||||
New Bundle Features
|
||||
===================
|
||||
|
||||
Ceph Base Bundles
|
||||
~~~~~~~~~~~~~~~~~
|
||||
|
||||
A development ceph-base bundle was published as preview at 17.08. It is now
|
||||
validated with x86_64 (amd64), aarch64 (arm64), and ppc64el (Power8), and a
|
||||
stable ceph-base bundle is published to the charm store with the 17.11 release.
|
||||
|
||||
The bundle provides an example for deploying a stand-alone Ceph Luminous
|
||||
cluster on Ubuntu 16.04 LTS.
|
||||
|
||||
Deprecation Notices
|
||||
===================
|
||||
|
||||
The legacy "ceph" charm is deprecated and will not receive updates past
|
||||
February 2018 (18.02). At this time, all deployments should be using the
|
||||
ceph-osd + ceph-mon deployment method.
|
||||
|
||||
Queens is the final supported OpenStack release for this charm.
|
||||
|
||||
Artful is the final supported Ubuntu release for this charm.
|
||||
|
||||
Xenial is the final supported Ubuntu LTS release for this charm.
|
||||
|
||||
There will not be a Bionic series legacy ceph charm developed or released.
|
||||
|
||||
Existing users of the legacy ceph charm should refer to Appendix A of the
|
||||
Charm Deployment Guide for details of how to migration existing deployments
|
||||
to the preferred ceph-mon and ceph-osd charms.
|
||||
|
||||
https://docs.openstack.org/charm-deployment-guide
|
||||
|
||||
ZeroMQ messaging support across the charms will be removed during the Queens
|
||||
development cycle.
|
||||
|
||||
PostgreSQL database support across the charms will be removed during the
|
||||
Queens developement cycle.
|
||||
|
||||
Deploy from Source (DFS) support is under review for sustainability and may be
|
||||
removed during the Queens development cycle.
|
||||
|
||||
Known Issues
|
||||
============
|
||||
|
||||
hacluster scale-out
|
||||
~~~~~~~~~~~~~~~~~~~
|
||||
|
||||
By default, the hacluster charm will assume a cluster size of three units; in
|
||||
order to scale a three unit clustered application out, you must increase the
|
||||
cluster-count configuration option to the target size prior to adding the
|
||||
additional units to the clustered application.
