• What is the current behavior?
  There is no documentation of which docker permissions are required.

• What is the motivation / use case for changing the behavior?
  I'm wary of giving containers unrestricted access to the docker socket and would like to expose it via docker-socket-proxy and the DOCKER_HOST environment variable with limited permissions.

Two things about this:

Using DOCKER_HOST is currently not supported. It should be though so I openend an issue to track this #69

I have never used docker-socket-proxy so I am not sure about how exactly configuring it would work in this context. docker-volume-backup definitely needs CONTAINER and SERVICE, it will also need POST but I cannot tell you what else is required. You can grep for s.cli in the source directory to find all calls being done here.

Using DOCKER_HOST is now supported as of v2.12.0.

Thanks for the quick update, I'll experiment and post the results here.

It works, thanks. I'm not using swarm so it works with just POST and CONTAINERS.
