The 17.02 OpenStack Charm release includes updates for the following charms:
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 https://releases.openstack.org/ocata
To deploy OpenStack Ocata on Ubuntu 16.04, use the ‘openstack-origin’ configuration option, for example:
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:
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.
ceph based cinder storage backends¶
OpenStack Ocata changes the behaviour of cephx key management for ceph based cinder storage backends; as a result, nova-compute units must now have copies of the key used by the cinder backend for managing ceph storage. To support sharing of these keys, users must add a relation between the cinder-ceph and nova-compute charms:
juju add-relation nova-compute cinder-ceph
For more details please see:
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:
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:
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 utilised 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.
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.
The use-embedded-webserver option has been removed from this charm and should be dropped from any bundles.
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:
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.
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:
juju upgrade-charm cinder
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.
ceilometer and aodh + Juju 1.25/MAAS 1.9¶
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.
