https://github.com/kubernetes-sigs/aws-load-balancer-controller/issues/3649

Description

There is a similar pr open for the kubernetes libs, but there haven't been any updates in a few weeks.

In the comments of that pr there is a comment:

yes we plan to upgrade the controller-runtime to v0.15+, but it has breaking changes and may need more time and efforts to investigate and implement corresponding changes. I think we need to do it sooner than later. Any community contribution is very welcome. Thanks.

This PR is to address the k8s 1.29 dependency updates and refactoring required (the bulk of the changes) to update the controller runtime to v0.15+. Also sets the go version 1.22.

Two tests were removed that were related to decoder injection that is no longer possible in new versions of controller runtime. Two other tests were removed that checked ingresses were deleted there was a deletion timestamp with no finalizer. This is no longer possible because controller-runtime sets the DeletionTimestamp to nil on Create(). Because of this the DeletionTimestamps were also removed from the deleted ingress with finalizer tests.

Hi @larntz. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.

@aaroniscode and @oliviassss This is related to pr 3675 and issue 3649. I can't push changes to that PR so I created this one.

While I'm checking the code changes, can you try to run the failed test suites locally for a quicker debug? you can try to use ginkgo cmd with --focus option to focus on the specific suites. Something like

  ginkgo -focus "<test description>" -timeout 2h -v -r test/e2e -- \
    --kubeconfig=${CLUSTER_KUBECONFIG} \
    --cluster-name=${CLUSTER_NAME} \
    --aws-region=${AWS_REGION} \
    --aws-vpc-id=${cluster_vpc_id} \
    --helm-chart=${HELM_DIR}/aws-load-balancer-controller \
    --controller-image=${CONTROLLER_IMAGE_NAME} \

@oliviassss yes, I will work on that this evening.

[larntz]

I was able to test this some. I found on this failing test that two ingresses get created in one namespace and one or both are missing the group ingress finalizer metadata. Not sure yet if that's a symptom or cause of the failing test. I will continue troubleshooting, but wanted to provide an update.

[larntz]

@oliviassss I think this is ready for a more in depth review now. If you need anything else from me let me know. Thanks!

[oliviassss]

@larntz, thanks! I left some comments

@larntz Thanks for making this change, it's much helpful and looks pretty solid. However, i noticed there are two changes

1. changed the lease to lease only instead of configmaplease. Can we revert this change and do it in a separate PR(may be can be deferred to a minor version release)
2. the rtCfg.Namespace is not passed to caches.

I tested this locally last night but now realize I didn't update the image tag. I'll work on fixing this today. Apologies for the noise.

Merging this PR right now. We need to conduct thorough tests on it before shipping it to users. For example, need to test across k8s versions and aws regions, as well as the features this PR amended, like ingressclassparam, webhookcerts, tgb, etc.
