Warning Overview

Please use Liberty 1.1.0 tag or later when using Kolla. No data loss

Resolution
----------
To rectify this problem, we plan to have a release of 1.1.0-rc1 on
April 1st, 2016. We plan our final releae of 1.1.0 on April 15th, 2016. The
work going into this version will be:
To rectify this problem, the OpenStack release and infrastructure teams
in coordination with the Kolla team executed the following actions:
* Move forward to Docker 1.10.z as a minimum dependency.
* Move to named volumes to remove data loss scenario.
* Backport upgrade playbooks from Mitaka so Operators may effectively manage
OSSA and CVE advisories in their OpenStack cloud without being forced to
migrate to Mitaka.
* Backport thin-containers for Neutron agents.
* Backport Kolla's docker integration module to remove the hard pin on
Docker 1.8.2.
* The Kolla community expects the docker containers themselves to be
minimally modified.
* Deleted the stable/liberty branch (where 1.0.0 was tagged from)
* Created a tag liberty-early-demise at the end of the broken stable/liberty
branch development.
* Created a new stable/liberty branch based upon stable/mitaka.
* Corrected stable/liberty to deploy Liberty.
* Released Kolla 1.1.0 from the newly created stable/liberty branch.
End Result
----------
A fully functional Liberty OpenStack deployment based upon the two years of
testing that went into the development that went into stable/mitaka.
The docker-engine 1.10.0 or later is required.
