Im trying to run a pi-hole docker container and get the error message "no matching manifest for linux/mipsle in the manifest list entries"

Question

Update: It turns out it can't install pi-hole due to it not officially supporting the CPU architecture ("mips"). It has however been performed by https://www.reddit.com/r/pihole/comments/fnhfb8/pihole_for_mips_ci20/ that guy, but I'm not sure how to modify the yml file to retrieve his code instead of the official pi-hole code. Everything needed should be in this post, hopefully.

I'm trying to run docker pi-hole and after configuring the .yml file, creating folders for the volumes, and creating fixed routes, I get the error message: "no matching manifest for linux/mipsle in the manifest list entries" when trying to run the container. I'll include all the commands I used in case I typed anything strange.

Any help with decoding and solving this error message will be greatly appreciated.

making volumes

mkdir -p ./pihole/etc-pihole/
mkdir -p ./pihole/etc-dnsmasq.d/
mkdir -p ./pihole/var-log/
mkdir -p ./pihole/var-log/lighttpd
chown 33:33 ./pihole/var-log/lighttpd
mkdir -p ./pihole/etc-cont-init.d/

setting routes

echo '#!/usr/bin/with-contenv bash
set -e

echo "fixing routes"
ip route del default
ip route add default via 172.18.0.1
echo "done fixing routes"' >> ./pihole/etc-cont-init.d/10-fixroutes.sh
chmod 755 ./pihole/etc-cont-init.d/10-fixroutes.sh

running the container

cd ~
docker-compose up -d pihole
