volumes.Get was not checking for symlinked paths meanwhile when adding a new volume it was following the symlink. So when trying to use a bind-mount that is a symlink, the volume is added with the correct path, but when another container tries to use the same volume it got a "Volume exists" error because volumes.Get returned nil and as such attempted to create a new volume.
