It was a few things but the biggest issue was that upstream docker was in-flight on retiring the old image format (V1) in favor of the new one (V2) which has implications on how a "non-native" docker build system (read: something other than the docker daemon) can import/export docker images to and from a registry which required a lot of re-engineering the backend of the OSBS build system. Basically the "docker save" functionality disappeared in V2 upstream without any replacement. This work is mostly done and the build system can work with V2 registries now. I'm also not entirely sure this is a "system wide change" as others might classify it. For people who are just using Fedora, if we missed the deadline or messed something up, they wouldn't notice so it's possible this needs to change in classification. -AdamM > > Thanks. > > Tomas > >> Regards, >> Jan >> >>> [1] https://fedorahosted.org/fesco/ticket/1461 >>> >>> Thanks! >>> >>> Regards, >>> -- >>> Tomas Hozza >>> Software Engineer - EMEA ENG Developer Experience >>> >>> PGP: 1D9F3C2D >>> UTC+1 (CET) >>> Red Hat Inc. http://cz.redhat.com >>> -- >>> devel mailing list >>> devel@xxxxxxxxxxxxxxxxxxxxxxx >>> http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx >> >> >> > > -- > Tomas Hozza > Software Engineer - EMEA ENG Developer Experience > > PGP: 1D9F3C2D > UTC+1 (CET) > Red Hat Inc. http://cz.redhat.com > -- > devel mailing list > devel@xxxxxxxxxxxxxxxxxxxxxxx > http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx http://lists.fedoraproject.org/admin/lists/devel@xxxxxxxxxxxxxxxxxxxxxxx
