Nginx ingress — Error retrieving resource lock, ingress pods missing load balancer IP addresses

We have been deploying nginx ingress on our AKS clusters for a while now using deployment files. Recently we upgraded ingress deployment to use helm charts instead of individual deployment files.

With this upgrade, we encountered two issues:

1. When we list down the ingress of all our apis, they are missing ip address

In addition, when we export ingress yaml, it was missing loadbalancer ip

kubectl get ingress -o yaml

2. In ingress controller logs, we are continuously seeing below error related to controller leader election

The error message points us to a permission issue with service account used for ingress controller…
