Support for docker compose would be fantastic. I could envision this on a digital ocean droplet with docker compose and traefik would become my go-to method for hosting. It's already an amazing tool, though!
Mind describing the case in bit more of details? I find that I can learn on interesting approaches, especially in cases where I cannot see direct benefits/use case - i.e. here I'm not sure why and even how I'd want docker-compose to be synced - I feel there is a hidden gem in your idea!
