this is nice, hopefully DHH and the folks working on Kamal adopt this.

the whole reason I didn't end up using kamal was the 'need' a docker registry thing. when I can easily push a dockerfile / compose to my vps build an image there and restart to deploy via a make command

Build the image on the deployment server? Why not build somewhere else once and save time during deployments?

I'm most familiar with on-prem deployments and quickly realised that it's much faster to build once, push to registry (eg github) and docker compose pull during deployments.

I think the idea with unregistry is that you're still building somewhere else once but then instead of pushing everything to a registry once you push your unique layers directly to each server you're deploying.

I don't see a reason to not adopt this in Kamal. I'm also building Uncloud that took a lot of inspiration from Kamal, please check it out. I will integrate unregistry into uncloud soon to make the build/deploy process a breeze.
