📝 Walkthrough

Walkthrough

The IngressController API now accepts only "3.2" for HAProxyVersion, and the HAProxyVersion28 constant was removed. The specification documentation states that upgrades from OpenShift 5.0 with haproxyVersion set to "2.8" are blocked. The status documentation lists only "3.2" as the effective version example. The feature tests no longer include cases that configure or update to "2.8".

Update the HAProxy version integration fixture.

operator/v1/tests/ingresscontrollers.operator.openshift.io/IngressControllerMultipleHAProxyVersions.yaml still expects "2.8" to be accepted. It also expects validation errors to list "2.8", "3.2". This validation now accepts only "3.2", so those tests will fail. Remove the obsolete 2.8 case and update the expected error messages.

When was the 2.8 option deprecated? What are the other valid user choices and when were they introduced?

What will tell a user in 5.0 that they must move off of 2.8 before an upgrade to 5.1?

We implemented an upgradeable condition in ingress operator: openshift/cluster-ingress-operator#1517

The 5.0 API doc also states that the 2.8 version is for migration purposes only (pinned version) and should be dropped in the next version.

Valid choices for 5.1: 3.2 and we're planning to add 3.4 as a non default option as well for early adopters.

@JoelSpeed removing test per this comment. It is version dependent, we'd need to update it every time we bump version in the API.

It seems we need to have a test until we remove the feature-gate annotation. So instead of removing the test, I made it simpler so we have just a few updates when we make changes to the API.

This verifier checks all files that have changed. In some cases you may have changed or renamed a file that already contained api violations, but you are not introducing a new violation. In such cases it is appropriate to /override the failing CI job.

Is this expected on verify-crdify and verify-crd-schema since we are removing an enum?
