So I think that because the devstack job for config is requiring nova and neutron, and nova pulls in glance, that is why.

I think those jobs were started before containerized openstack support, so I don’t think we need nova and neutron anymore.

I’m trying this review

If that does not work, we likely just need to turn off devstack job for config.

Our env (sysinv) uses postgres, and perhaps postgres support has been dropped in train.

Why would config be setting up a glance db ?

Subject: [Starlingx-discuss] StarlingX devstack jobs randomly failing

The devstack zuul jobs for config are failing.

The error looks to be a database migration failure when initializing the glance DB

These are the DB components being installed

psycopg2 2.8.3

SQLAlchemy 1.3.6

Sqlalchemy_migrate 0.12.0

I think this may be due to this upstream commit which merged this morning

https://review.opendev.org/#/c/665606/

I don’t have any idea on how to fix this. We can disable the jobs, or remove glance from our devstack jobs, but we are blocked until this is resolved.

It may affect other flock repos as well, if they also have devstack jobs that are setting up glance.
