In the ovn-org/ovn-kubernetes repo we currently have two fedora dockerfiles:

• Dockerfile.fedora - this one is used for building the image that's used in CI (with fedora OVS/OVN RPMs).
• Dockerfile.fedora.dev - this one is only used by developers (manually) if they want to build custom images with OVS/OVN built from source (see OVS_REPO/OVS_BRANCH/OVN_REPO/OVN_BRANCH)

In the ovn-org/ovn repo we currently have another fedora dockerfile:

• Dockerfile - this one is used to build an ovn-kubernetes image with OVS/OVN built from source from the tree this is executed in.

It's probably a good idea to consolidate all these into a single Dockerfile (maybe hosted in the ovn-kubernetes repo).  This single Dockerfile can be parametrized through arguments that allow selecting whether the OVS/OVN rpms should be built from source (and where that source is) or if official fedora rpms should be used.
