Description Daneyon Hansen 2020-06-24 17:30:25 UTC 
Description of problem:
AWS Endpoints are not removed from status of infrastructures.config.openshift.io after being removed from spec.

Version-Release number of the following components:
Cluster version is 4.6.0-0.nightly-2020-06-23-160540

How reproducible:
100%
Steps to Reproduce:
1. Install a 4.6.0 cluster
2. Update spec of infrastructure/cluster, for example:
  platformSpec:
    aws:
      serviceEndpoints:
      - name: route53
        url: https://route53.amazonaws.com

3. Verify status of infrastructure/cluster has been updated.
4. Remove the changes from step 3.
5. Verify status of infrastructure/cluster has NOT been updated.

Actual results:
Status still shows:

  platformSpec:
    aws:
      serviceEndpoints:
      - name: route53
        url: https://route53.amazonaws.com

Expected results:
That status was updated after removing serviceEndpoints from spec.

Additional info:
The following EP added custom endpoint support:

Comment 1 Abhinav Dahiya 2020-06-24 18:05:47 UTC 
> https://github.com/openshift/cluster-config-operator/blob/3ff40a9228ec536487ab392a6c2ec41a55e5e7cc/pkg/operator/aws_platform_service_location/controller.go#L78-L81

seems like the controller doesn't reconcile on reseting the list to zero.. as it treats that as no-op, 

we should change it to skip only when spec and status match, and not len == 0
Comment 2 Abhinav Dahiya 2020-06-29 17:16:43 UTC 
this should be a blocker for 4.6 but we won't be able to get to it because of higher priority bugs.
Comment 6 Yunfei Jiang 2020-08-17 07:55:26 UTC 
verified. PASS.
