Good morning! I'm using metallb, and want to have multiple nginx ingress controllers in RKE2. Does anyone know how to add mutiple nginx ingress controllers in RKE2 that utilize metallb IPs?

I'm assuming you have an address pool configmap for metallb. Add an annotation to your LoadBalancer service with one of the below or both.

<http://metallb.universe.tf/address-pool|metallb.universe.tf/address-pool>: <name of your address-pool if set>
    <http://metallb.universe.tf/loadBalancerIPs|metallb.universe.tf/loadBalancerIPs>: <ip in the pool range>

Also a quick search in the metallb docs also has this information.
