Open Stack

So, my $0.02.

A supported/recent version of a tool to install an unsupported version of a software is not a bad thing.

OpenStack has a bad reputation (somewhat deservedly) for being hard to upgrade. This has mostly gotten better over time but there are still a large number of older, unsupported deployments at this point.

Sometimes, burning down the cloud isn't an option and sometimes upgrading in place isn't an option either, and they are stuck on an unsupported version.

Being able to deploy with a more modern installer the same version of the cloud your running in production and shift the load to it (sideways upgrade), but then have an upgrade path provided by the tool would be a great thing.

Thanks,
Kevin

So my 0.02$

Problem with handling Newton goes beyond deployment tools. Yes, it's
popular to use, but if our dependencies (openstack services
themselves) are unmaintained, so should we. If we say "we support
Newton" in deployment tools, we make kind of promise we can't keep. If
for example there is CVE in Nova that affects Newton, there is nothing
we can do about it and our "support" is meaningless.

Not having LTS kind of model was issue for OpenStack operators
forever, but that's not problem we can solve in deployment tools
(although we are often asked for that because our communities are
largely operators and we're arguably closest projects to operators).

I, for one, think we should keep current stable policy, not make
exception for deployment tools, and address this issue across the
board. What Emilien is describing is real issue that hurts operators.
