MetalLB — Manual Setup

MetalLB is not included in bootstrap.sh deploy. It must be installed manually before deploying traefik-internal (which depends on the MetalLB loadBalancerClass).

helm repo add metallb https://metallb.github.io/metallb
helm repo update
helm dependency build charts/metallb
helm upgrade --install metallb charts/metallb -n kube-system --wait

The chart wraps the upstream MetalLB subchart and adds a custom IPAddressPool + L2Advertisement (defined in charts/metallb/templates/pool.yaml). The pool assigns a single IP (10.0.1.250) with autoAssign: false, so only services that explicitly request the internal pool via annotation get that IP.
