New Charm Features

ceph-radosgw: multisite replication

The ceph-radosgw charm now features support for replication between RADOS Gateway deployments; please refer to Appendix J of the charm deployment guide for more details.

rabbitmq integration refactor

Rabbitmq sectional configuration was deprecated and removed, replaced by transport_url configuration in the [DEFAULT] section. As part of this change, a wider refactoring of the rabbitmq-server integration was done.

The ceilometer-agent charm now requires a direct amqp relation to the rabbitmq-server charm.

Users upgrading the ceilometer-agent charm to the 19.04 charm revision will need to add a relation, as ceilometer-agent units will go into a BLOCKED state for lack of this new required relation. Users and operators will also need to update any relevant bundles accordingly.

For example:

juju add-relation ceilometer-agent:amqp rabbitmq-server:amqp

Reference:

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, for example:

juju upgrade-charm keystone

Charm upgrades and OpenStack upgrades are two distinctly different things. Charm upgrades ensure that the deployment is using the latest charm revision, containing the latest charm fixes and charm features available for a given deployment.

Charm upgrades do not cause OpenStack versions to upgrade, however OpenStack upgrades do require the latest Charm version as pre-requisite.

Upgrading OpenStack

To upgrade an existing Queens based deployment on Ubuntu 18.04 to the Rocky release, re-configure the charm with a new openstack-origin configuration:

juju config nova-cloud-controller openstack-origin=cloud:bionic-rocky

Please ensure that ceph services are upgraded before services that consume ceph resources, such as cinder, glance and nova-compute:

juju config ceph-mon source=cloud:bionic-rocky
juju config ceph-osd source=cloud:bionic-rocky

Note

Upgrading an OpenStack cloud is still not without risk; upgrades should be tested in pre-production testing environments prior to production deployment upgrades.

See https://docs.openstack.org/project-deploy-guide/charm-deployment-guide/latest/app-upgrade-openstack.html for more details.

New Bundle Features

Deprecation Notices

Removed Features

nova-cloud-controller: single-nova-consoleauth

The 'single-nova-consoleauth' feature has been removed from the nova-cloud-controller charm; this legacy feature has been superceeded by the use of nova-consoleauth daemons on all nova-cloud-controller units, sharing authentication tokens using memcached.

Cluster resources associated with this feature will be cleaned up up during charm upgrade.

If the charm is running in an HA deployment, a relation to memcached must be added to the nova-cloud-controller application:

juju add-relation nova-cloud-controller memcached
