I don't think that's a good solution in general unless you're confident that all of your deployments will use Docker Compose.

About 1/3 of my deployments are just static sites, and the rest all fit into a single Docker container, so integrating Compose would be a big increase in complexity.

I'd say Compose simplifies even your single-container deployments, as the compose file is the single place to set your env variables, port forwards etc.

That being said, you can use Watchtower without Compose. It's enough to run

  docker run -d -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower
