Liberty 1.0.0 Deployment Warning

Warning Overview

Please use Liberty 1.1.0 tag or later when using Kolla. No data loss occurs with this version. stable/liberty is also fully functional and suffers no data loss.

Data loss with 1.0.0

The Kolla community discovered in the of middle Mitaka development that it was possible for data loss to occur if the data container is rebuilt. In this scenario, Docker pulls a new container, and the new container doesn't contain the data from the old container. Kolla stable/liberty and Kolla 1.0.0 are not to be used at this time, as they result in critical data loss problems.

Resolution

To rectify this problem, the OpenStack release and infrastructure teams in coordination with the Kolla team executed the following actions:

  • 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.
