Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: error during container init: error mounting "/home/pie/dockerchris/pihole-unbound/pihole/config/resolv.conf" to rootfs at "/etc/resolv.conf": mount /home/pie/dockerchris/pihole-unbound/pihole/config/resolv.conf:/etc/resolv.conf (via /proc/self/fd/6), flags: 0x5000: not a directory: unknown: 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

beore this volume i was using the original volumes mention in the example but they also give same error. i have no idea how to make it work. please help me

It's trying to mount 'resolv.conf' as a directory not a file. Try doing touch resolv.conf to create the file (you might need to do rmdir resolve.conf if it has created a directory there) then restarting the container. You will probably also have to do it for 'pihole-dhcp.conf', 'pihole-static-dhcp.conf', '04-pihole-static-dhcp.conf' and 'pihole-FTL.conf'.
