kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.9.3/manifests/metallb.yaml
kubectl create secret generic -n metallb-system memberlist --from-literal=secretkey="$(openssl rand -base64 128)"

Configure metallb

mkip=$(minikube ip)
range=${mkip%%.${mkip##*.}}.200-${mkip%%.${mkip##*.}}.250
cat << EOF | kubectl apply -f -
