I'm trying to use tramp to communicate with a docker image. I've installed docker-tramp.el.

When I find-file starting with "/docker:", it correctly prompts me for ps's in the docker container, but after that point seems to think that my local home directory is the contents of that container.

I can confirm from the command line that docker exec will give me the proper contents of said container.

Is there some additional configuration that's needed to inform my tramp setup for docker?
