Ocata Series Release Notes

4.0.0

There any multiple options available to an operator with regards to how they wish to provision devices for use with Ceph OSDs. One of those is to co-locate the data and journal on a disk, which is done by marking a partition on that disk with KOLLA_CEPH_OSD[_CACHE]_BOOTSTRAP. If an unwitting user happened to confuse this with the partition based approach, they could wipe out their entire disk, resulting in data loss.

Infra team will start running python35 jobs target to replace current python34 jobs This is due to the change from Ubuntu Trusty to Xenial, where python3.5 will be available.

Designate is an OpenStack project, providing DNSaaS.

During the Newton cycle support for baremetal provisioning with bifrost was added to kolla. Bifrost is a collection of ansible roles and playbooks to deploy a standalone instance of ironic.

Nova cells are required as of Ocata release, before upgrade database should be created. Due a bug in Nova, only latest code can be used to create default cells. Ensure nova is fully updated and have this patch applied before start upgrade to Ocata https://review.openstack.org/#/c/420051/ or upgrade to Kolla 3.0.3 first.

In Newton cycle we included means to change various things in Kolla images using override file. Full customization guide can be found here http://docs.openstack.org/developer/kolla/image-building.html#dockerfile-customisation

  • In the Newton cycle a new kolla-host playbook was introduced. The kolla-host playbook is intended to prepare servers for use as kolla deployment hosts. The kolla-host playbook requires the nodes to have an os installed and be reachable via ssh. Currently the kolla-host playbook supports ubuntu 14.04, ubuntu 16.04 and centos 7.2 as target servers. See features section for more details.

Added performance monitoring stack based on InfluxDB, Telegraf and Grafana.

  • Move manila-share service to network node.
  • Kolla now deploys Nova in cells v2 mode.

In most of case, the disks used by ceph have different size. Use the default value 1 may block the ceph when one disk is full. Use the disk size as osd weight will more reasonally.

New Features

  • Implement Aodh ansible role
  • To produce a secret storage and generation system capable of providing key management for services wishing to enable encryption features.
  • Add ceilometer ansible role
  • The Ceph bootstrap will now pause requesting confirmation from the operator if it detects a bootstrap label on a disk with more than one partition. An operator may override this behaviour by setting the Ansible variable ‘ceph_osd_wipe_disk’ to ‘yes-i-really-really-mean-it’.
  • When Cinder, iSCSI and the LVM driver are enabled, check that the appropriate volume group exists on the target nodes.

  • Add a new variable for the Ceph role, ‘kolla_ceph_use_udev’, which when set to ‘False’ relies on system tools such as sgdisk/blkid to read the necessary disk info required to bootstrap Ceph disks on older systems. Most operators should not need to change this.
  • Designate deployment through Ansible with Bind9 as backend for DNS.
  • Implement Ansible Tempest role
  • A new deploy-bifrost command was added to kolla-ansible. The deploy-bifrost command will deploy and bootstrap a standalone instance of ironic in a single container.

Known Issues

  • The performance monitoring stack currently in use in Kolla is experimental. The components used to compose the performance monitoring stack may change in Ocata, and the implementation will certainly be far improved in Ocata.

Upgrade Notes

  • Heka is deprecated and is replaced with Fluentd
  • Version of Ceph has been changed from Hammer to Jewel
  • should move use header and footer block in template overrides file
  • Kibana version changed from 4.4 to 4.6.
  • The wrong service type of the Mistral keystone endpoint was fixed. Prior to a upgrade manually change the service type of an existing Mistral keystone endpoint from ‘application_catalog’ to ‘workflowv2’.
  • Is required that for the generic driver the manila-share service should be run on the network node. The generic driver is our default driver, so this change is needed.
  • There is new required option in passwords.yaml - placement_keystone_password. To populate this variable with random password, simply add it to passwords.yaml and re-run kolla-genpwd
  • There is new required group in inventory. Please add these lines to your inventory:

    [placement:children] control

    [placement-api:children] placement

  • RabbitMQ version was increased to 3.6.2
  • Fedora based Docker images were removed. Fedora based Docker images were deprecated as of the Newton release cycle.
  • cinder_rbd_secret_uuid variable is requirement in passwords.yml file
  • the os_initial_weight still has the default value 1, it will not break cluster when upgrading.

Deprecation Notes

  • Nova network was deprecated in the Nova project in April 2016. The nova-network container is deprecated as of the Newton release and will be removed in the future.
  • Heka is deprecated and will be replaced in Ocata cycle
  • The nova-network was deprecated, we remove it from the nova ansible role.

Security Issues

  • The kolla-host playbook will create a kolla user on all nodes using the ssh-key specified in the passwords.yml. The kolla user will be granted passwordless sudo privileges on the host. this behavior can be disabled by setting create_kolla_user=False

Bug Fixes

  • Change Barbican default secret store to pkcs11 instead of default one. Add barbican_p11_password to passwords.yml
  • The wrong urls of Cinder Service endpoints was fixed.
  • Integrates gnocchi with ceph to resolve the the lack of HA.

Other Notes

  • Congress doesn’t work correctly out of the box and will not deploy. See Bug
  • Reducing disk footprint for Ubuntu/Debian images by only installing English locales and no documentation files.
