Apologies if this information can be found somewhere else, but I have been unable to find it so far. Perhaps somebody can answer my question or point me in the right direction.
Thank you very much.
For Fedora CoreOS, it’s the same kernel version as in the other images, which you can query via our metadata endpoint, e.g.
https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200323.3.2/x86_64/commitmeta.json
See also the main meta.json:
https://builds.coreos.fedoraproject.org/prod/streams/stable/builds/31.20200323.3.2/x86_64/meta.json
Thank you so much, this is what I was looking for!
