MetalLB Installation: https://metallb.universe.tf/installation/

Installation By Manifest

To install MetalLB, apply the manifest:

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.3/manifests/namespace.yaml kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.3/manifests/metallb.yaml

On first install only

kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)"

The installation manifest does not include a configuration file. MetalLB’s components will still start, but will remain idle until you define and deploy a configmap.
