NotAuthorizedOrNotFound in NLB Kuberentes Ingress Controller

[passarela]

Is this a BUG REPORT or FEATURE REQUEST?

BUG REPORT

Versions

CCM Version: v1.24.0

What happened?

When using "loadBalancerIP" in the Nginx Ingress Controller manifest. LoadBalancer returns failure

What you expected to happen?

When specifying reserved IP in "loadBalancerIP" manifest, load balancer must be created with specified IP

How to reproduce it (as minimally and precisely as possible)?

1. Create an Oracle Cloud Reserved IP

2. Insert LoadBalancerIP into the manifest:
   kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v1.5.1/deploy/static/provider/cloud/deploy.yaml

4. It should return the error in NLB:
   (404, NotAuthorizedOrNotFound, false) Authorization failed or requested resource not found.
   

Anything else we need to know?

I'm creating according documents:
https://docs.oracle.com/en-us/iaas/Content/ContEng/Tasks/contengcreatingloadbalancer.htm#contengcreatingloadbalancer_topic_Specifying_Load_Balancer_Reservado_IP

I have full permission on my tenancy.
The Reserved IP is on the same IP as the Cluster...
If I don't specify LoadBalancerIP, the LB is successfully created!

It depends on how you have configured the IAM permissions for CCM. CCM should be having permission to use the reserved IP.
A policy like below might be needed for this to work. Note this example assumes you add all instances which can run CCM into a dynamic group and use instance principal based auth for CCM

ALLOW dynamic-group ccm-dynamic-group to use private-ips in TENANCY
ALLOW dynamic-group ccm-dynamic-group to manage public-ips in TENANCY
