Pre-Release Charms

Deprecated Charms

New Charm Features

OpenStack <O7K_RELEASE> Support

The charms provide full support for OpenStack <O7K_RELEASE>. For further details and documentation on Openstack <O7K_RELEASE> please check out https://releases.openstack.org/<O7K_RELEASE>.

Use the openstack-origin charm configuration option to declare the intended OpenStack version, for example:

cat > config.yaml << EOF
nova-cloud-controller:
  openstack-origin: cloud:xenial-<O7K_RELEASE>
EOF

juju deploy --config config.yaml nova-cloud-controller

Also see the published example bundles.

Feature Title 1

Feature Title 2

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

When upgrading ceilometer to <O7K_RELEASE>, an identity-credentials relation needs to be added between ceilometer and keystone. If this relation is not added, the ceilometer charm will indicate it is in a blocked state via workload status.

To upgrade an existing Pike based deployment on Ubuntu 16.04 to the <O7K_RELEASE> release, re-configure the charm with a new openstack-origin configuration:

juju config nova-cloud-controller openstack-origin=cloud:xenial-<O7K_RELEASE>

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:xenial-<O7K_RELEASE>
juju config ceph-osd source=cloud:xenial-<O7K_RELEASE>

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

<O7K_RELEASE> Support in Example Bundles

<O7K_RELEASE> versions of the example bundles are published in the charm store under cs:openstack-base, cs:openstack-telemetry. The stand-alone ceph bundle is also updated at cs:ceph-base. These bundles have been validated on x86_64, arm64, s390x and ppc64el architectures with Juju 2.3.3 and MAAS 2.3.0.
