MetallB setup changes

Hi Everyone,

It has been a while since I setup MetallB and I have come across some changes that you can find here:

https://metallb.universe.tf/configuration/

Now for the Layer 2 configuration you need to create IPAddressPool and and L2Advertisement.

So for a quick install as per the documenation:

kubectl apply -f https://raw.githubusercontent.com/metallb/metallb/v0.13.10/config/manifests/metallb-native.yaml

then create a yaml file, like this IpaddressPool.yaml with contents (these are IPs from the documentation you need to replace with your own):

apiVersion: metallb.io/v1beta1
kind: IPAddressPool
metadata:
  name: first-pool
  namespace: metallb-system
spec:
  addresses:
  - 192.168.1.240-192.168.1.250

Then:

kubectl apply -f IpaddressPool.yaml

Next the advertisement L2advertise.yaml:

apiVersion: metallb.io/v1beta1
kind: L2Advertisement
metadata:
  name: example
  namespace: metallb-system

kubectl apply -f L2advertise.yaml
