Pi hole inside docker in raspberry pi 4 with openwrt question


I'm using a raspberry pi4 as a router with OpenWrt. I have an extra raspberry pi 3b that I was initially thinking of using as a DNS server (raspbian with pi hole), however, maybe I can safe it and just get a docker container in my pi4 with rpasbian + pihole.

Is this a good idea? or should I go with the separate setup?

I was thinking the same thing before, but the process of docker (using it as user few times some times ago) seems far more complicated especially with the network setting etc.

maybe others have better experience?
