A category or forum for cloud build activity (such as AWS AMIs)?

i am curious where there is or might be activity discussion (not necessarily detailed) regarding the building of “ready to run” cloud images (or VM images) for the recently current version of Ubuntu (focal 20.04 at the time of this post). i am not looking for support. i’m interested in the activity of what variations of images are being worked on. i might have some time to do some testing or wrapping things in some scripting (Python and Bash).
