Pihole v5 - "attempting to write to readonly database" (Have already read previous posts)

[Altecice]

Hey guys,

So I recently installed the Pihole/Pihole:latest docker container on my Portainer install and its all working as intended but I cannot add to my addlists I get the error "attempt to write a readonly database"
I have already read over some previous threads regarding missing permissions and I have attempted to replicate their success but its still broken for me.

Output of commands:

ls -lh /etc | grep pihole
drwxr-xr-x  1 pihole root   4.0K Jun 19 00:09 lighttpd
drwxrwsr-x+ 3 pihole pihole 4.0K Jun 19 00:28 pihole

ls -lh /etc/pihole/gravity.db
-rw-rw-r--+ 1 pihole pihole 5.0M Jun 19 00:10 /etc/pihole/gravity.db

groups pihole
pihole : pihole www-data

I have already attempted to add the www-data to the pihole user via "usermod -a -G pihole www-data"
then a reboot, still not working

Ok so a bit of an update:

If I run chmod 777 on my host /pihole/gravity.db I can modify the database until I reboot ( I assume the ACL gets reset)

before restart

root@omv:/srv/d1d9f653-e52b-4725-8611-445a70a553f1/pihole/pihole# getfacl gravity.db
# file: gravity.db
# owner: openmediavault-webgui
# group: openmediavault-config
user::rwx
group::rwx
other::rwx

after restart

root@omv:/srv/d1d9f653-e52b-4725-8611-445a70a553f1/pihole/pihole# getfacl gravity.db
# file: gravity.db
# owner: openmediavault-webgui
# group: openmediavault-config
user::rw-
group::rw-
other::r--

running the command setfacl -Rbn on that file or the pihole directory the file resides within it will still get reset upon reboot of the container.
