[BUG REPORT] When creating a Load Balancer the backends of the backend set (TCP 80) are not created automatically. #423

Open GBT55 opened 1 year ago

Is this a BUG REPORT or FEATURE REQUEST?

BUG REPORT

Versions

CCM Version: v1.25.0

Environment:

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/
