Sorry, the new GitHub UI is awful, I thought I was opening this up on my local repo first. I wanted to test building on prs as well as releases

Thanks for the PR @jzucker2 - I'm new as a maintainer here so apologies if I'm missing some context, but why the change in registries? The workflow you've provided looks solid - its just changing from docker hub to github repos gives me pause, as this would be a change in where users can look up the image / we'd need to clearly communicate such a change.

Sorry in advance if this was already discussed

Wasn't discussed. I was trying to open this in my repo first, but GitHub's new PR UI is just awful and led me here instead. I couldn't track how the pr tags were generated in that custom docker action so I was just messing around with another approach. This is absolutely not ready for merging
