Hi,
I made a simple Docker image for Duplicacy CLI, available on Github. Nothing extraordinary, but at least it supports the most common architectures (amd64, i386, armv6, armv7, arm64).
Don’t hesitate to give me your feedback if you try it 
Can you elaborate on what’s the point/benefit/reason? Duplicacy is already self-contained executable (just like any other go software). It does not benefit from dependencies isolation that docker provides. I can understand container that provides extra functionality like this one
But what is the benefit of adding docker layer that simply swaps your host user mode environment with that of alpine?
Good points, but there is at least one good reason : I need to backup Docker named volumes. This is the recommended way from the Docker documentation: https://docs.docker.com/storage/volumes
Maybe I should update the README with named volumes instead of bind ones.
