So I have been working on setting up my homelab for a couple days now and I have broken more stuff than actually making something usable My objective - setup a basic homelab using k3s with a few services running on it like Pihole, Grafana, plex and host some pdf/epub files I had the idea of using tailscale since i wanted to use pihole to enable network ad blocking on all my devices that are connected to the tailscale network that way i would actual feel like im using my homelab daily. The Problems: I am constantly running into dns issues with pihole tailscale and ubuntu systemd-resolved. i start with a master node and a worker node and then use a deployment manifest to pull the pihole docker image and create a deployment on my cluster for 1 pod to run on my worker node. That all works out but when i add the tailscale ip of my worker node to my tailscale dns settings and make it override it just blocks everything and none of my devices can access internet at all. according to the logs the pod seems to be running fine but due to some dns issues and also returns the following when i try to use nslookup command by passing the tailscale ip of my worker node “DNS request timed out. timeout was 2 seconds. Server: UnKnown Address: 100.70.21.64 DNS request timed out.“I have looked up on various blogs and youtube videos but i am not able to resolve my issue. I know simply running a pihole docker container or the pihole service itself would be much easier and probably work out of the box but i want to learn k8s properly and its also part of my homelab so i do not want to do it just for the sake of running it but rather i wanna learn and build somethingi would also want that if possible will i be also somehow able to access the other services on my cluster through the tailscale network routing
