No need to indicate "built on Ubuntu" for docker image tags.
Alpine tag is specifically used as it used different libraries and image size is small.  Ideally, for Docker images, we should use Alpine Linux.  If OVS for Alpine is latest, then image size will be further reduced.

Note thAt at the end of the day, container is just a delivery or packaging vehicle.

If it can add appropriate OVS packages like https://github.com/servicefractal/ovs/blob/master/Dockerfile is better as they are already tested.   Building OVS as a part of this will cause more testing impacts and is unnecessary.  The objective is to run OVS in a container image.  I would keep it simple.

Hence, I am ok with the approach you proposed by publishing single image for each stable release leveraging host kernel modules. I have pushed  2 debian images for each stable releases 2.11.2_debian and  2.12.0_debian under openvswitch/ovs accordingly. I also sent the corresponding patch https://patchwork.ozlabs.org/patch/1193372/ to refactor the docker builds to support an option to skip kernel modules for ovs repo so that user can choose to build/run with/without kernel modules. Let me know further.
