Docker error after install

[beetdb]

Hi,

I've followed the instructions 3 times for the Raspberry PI docker install.

I can get dashing start to work and have it working outside of docker but this is the error I get when I try to start it after a fresh install and copy of the config files that worked:

pi@cm0front00:~/hadashboard$ docker start hadashboard
Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "process_linux.go:359: container init caused "rootfs_linux.go:54: mounting \"/home/pi/hadashboard/lib/ha_conf.rb\" to rootfs \"/var/lib/docker/overlay2/fe81bf20c7502a1425c1ef9a5a9c30365912384f75ddd5c931c72a5d67e1d16d/merged\" at \"/var/lib/docker/overlay2/fe81bf20c7502a1425c1ef9a5a9c30365912384f75ddd5c931c72a5d67e1d16d/merged/app/lib/ha_conf.rb\" caused \"not a directory\"""
: Are you trying to mount a directory onto a file (or vice-versa)? Check if the specified host path exists and is the expected type

Any ideas or suggestions?
