metallb.universe.tf/allow-shared-ip doesn't work

[Oren Zipori]

Hi
I setup MetalLB for my RPI 4 cluster, I'm running metallb/controller:v0.9.5 using the manifest installation from the MetalLB installation page.
I'm trying to set my pihole to use metallb so i can run both UDP and TCP services on the same IP Address, But when the 2 services are created only one get the shared IP and the other is stuck at pending with this error:

failed to allocate IP for "pihole/pihole-tcp": can't change sharing key for "pihole/pihole-tcp", address also in use by pihole/pihole-udp

Does anyone know what cloud be the issue? from what I understand it supposes to work without any issues.

You probably created the sharing key after a service already had the
IP allocated. Can you please try, for example, to delete the k8s
services and create them from scratch with the annotation?

My issue was resolved by adding to the service resource the annotation of: externalTrafficPolicy: Local 

This with the edition of the metallb.universe.tf/allow-shared-ip: pihole enable my two services to run on the same IP. I don't understand why the externalTrafficPolicy fixed it but it did.
