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/libertybranch (where 1.0.0 was tagged from) - Created a tag liberty-early-demise at the end of the broken
stable/libertybranch development. - Created a new
stable/libertybranch based uponstable/mitaka. - Corrected
stable/libertyto deploy Liberty. - Released Kolla 1.1.0 from the newly created
stable/libertybranch.
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.
