Right now, I use ssh to trigger a docker compose restart that pulls all the latest images on some of my servers (we have a few dedicated hosting/on premise setups). That then needs to reach out to our registry to pull images. So, it's this weird mix of push pull that ends up needing a central registry.

What would be nicer instead is some variation of docker compose pussh that pushes the latest versions of local images to the remote host based on the remote docker-compose.yml file. The alternative would be docker pusshing the affected containers one by by one and then triggering a docker compose restart. Automating that would be useful and probably not that hard.
