Is this a BUG REPORT or FEATURE REQUEST?

BUG REPORT

Versions

CCM Version: v1.25.0

Environment:

  • Kubernetes version (use kubectl version): v1.25.9
  • OS (e.g. from /etc/os-release): Ubuntu 22.04.2 LTS
  • Kernel (e.g. uname -a): Linux kow-m02 5.15.0-1032-oracle Update to latest SHA of bmcs-go-sdk #38-Ubuntu SMP Thu Mar 23 19:30:10 UTC 2023 aarch64 aarch64 aarch64 GNU/Linux
  • Others:

What happened?

When creating a Load Balancer with the Nginx example from https://github.com/oracle/oci-cloud-controller-manager/blob/master/docs/tutorial.md the backends of the backend set (TCP 80) aren't automatically created.

What you expected to happen?

That the the backends of the backend set (TCP 80) would be created automatically.

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

Use the example from https://github.com/oracle/oci-cloud-controller-manager/blob/master/docs/tutorial.md and append the following annotations to the LB service:

annotations:
    oci.oraclecloud.com/load-balancer-type: "lb"
    service.beta.kubernetes.io/oci-load-balancer-shape: "flexible"
    service.beta.kubernetes.io/oci-load-balancer-shape-flex-min: "10"
    service.beta.kubernetes.io/oci-load-balancer-shape-flex-max: "10"
    service.beta.kubernetes.io/oci-load-balancer-subnet1: "ocid1.aaaaaaaaaa.aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"

Then this LB will be created, with a backend configured TCP 80, but empty of backends inside it
image

Anything else we need to know?

If I try to curl the web, this happens:

guille@raspberrypi: $ curl http://<LoadBalancer_IP>:80/
curl: (56) Recv failure: Connection reset by peer

But, If I create the backends myself (via the web console) then I'm able to connect to the webpage e.g.

guille@raspberrypi: $ curl http://<LoadBalancer_IP>:80/
