Kamal like Nix deployment tool

Hi! I was just wondering if anyone knows about a deployment tool that has the same focus as Kamal (the deployment tool from Basecamp), just based around nix-built docker images? I really like Colmena, but would preferably often like something that is based around container images, so that it is easier to quickly bootstrap a server, and get zero-downtime deployments working out of the box.

P.S. if this does not already exist (I atleast have not found it), I would be open to starting an open source project centered around this idea.
