Pihole error

Help docker
1

Hello,
I installed my pihole on raspberry pi 4, openmediavolt 5, docker, portainer.
I set it up according to the article: https://pcmac.biz/pi-hole-on-openmediavault-5-inside-docker-with-portainer-using-raspberry-pi-4/

It still reports an error when turned on. Log:

I really don't know what to do. Can someone please help me?

Please check that your Docker containers have access to that AppData volume in general. Root and non-root docker users.

Lots of NAS have permission schemes/restrictions outside the scope of docker and pi-hole that cause errors that look like yours:

chown: cannot access '/etc/pihole/dhcp.leases': No such file or directory
sudo: unable to stat /etc/sudoers: Permission denied

if you can't find any permission settings + docker interaction problems for MediaVault, maybe another folder path without these permissions would work better than AppData - not sure if thats possible, I don't have mediavault or portainer experience.

Thanks for the advice, it really was in the wrong permission settings.
