NOMAD Pi-hole / Unbound / Keepalived Replica

Repo stack path: /home/fizzlepoof/repos/truenas-stacks/pihole/nomad
Suggested live stack path: /opt/pihole-nomad
Node role: NOMAD backup / BACKUP1
VIP target: 10.5.1.53/24
LAN interface: enp5s0
NOMAD LAN IP: 10.5.1.16

Bring-up:

cd /opt/pihole-nomad
cp .env.example .env
bash bin/prepare_nomad.sh --up

Host note:

If systemd-resolved is using the local DNS stub on port 53, disable the stub listener on NOMAD before trusting Pi-hole for live DNS:

sudo mkdir -p /etc/systemd/resolved.conf.d
cat <<'EOF' | sudo tee /etc/systemd/resolved.conf.d/99-pihole.conf
[Resolve]
DNSStubListener=no
EOF
sudo systemctl restart systemd-resolved
sudo ln -sf /run/systemd/resolve/resolv.conf /etc/resolv.conf

Pi-hole on NOMAD is pinned to enp5s0 with FTLCONF_dns_interface=enp5s0 and FTLCONF_dns_listeningMode=SINGLE so it answers cleanly on the LAN IP without fighting Docker bridge noise.
