2 Different instances of Traefik receive the same external IP from MetalLB

[MichaelThamm]

Bug Description

When multiple Juju models have a traefik instance the latter one does not reach active/idle state because there was only 1 IP address in the pool. After re-enabling MetalLB with a range of IP addresses, both Traefik instances received the same IP address.

To Reproduce

1. sudo microk8s enable metallb:10.77.43.192-10.77.43.192
2. juju deploy traefik-k8s
3. sudo microk8s disable metallb
4. sudo microk8s enable metallb:10.77.43.192-10.77.43.195
5. kubectl get svc -A -o wide | grep -E "^NAMESPACE|traefik"
