Dear all,
It is now possible to use bodhi to release a new container build. Currently it is following the same flow as packages.
After a successful OSBS build, a bodhi update can be created. Fedpkg does not yet support creating updates for containers 
[0], so you have to either use bodhi web UI or the bodhi cli. For 
example
    bodhi updates new --type enhancement --notes "cockpit update to version 181-2"  cockpit-181-2.fc29
Once the update is pushed to testing, the container will be available in the registry with the testing tag
Thanks
