Deletion issue of Ingress Objects - API version "confusion"

[xakraz]

Hi there,

Context

• We are in the process of handling k8s 1.22 deprecated API removal, like extension/v1beta1 of ingresses replaced by networking.k8s.io/v1.
• We are using Argocd "App of Apps" pattern.
• We are running argo-cd v2.0.3+8d2b13d (yes we need to upgrade 😅 )

Observation

When using the cascaded deletion, we had Applications that were stuck in deletion while waiting for leaf resources to be deleted.

Troubleshooting

In the App of app Application objects we noticed

.status.operationState.syncResult.resources

- group: networking.k8s.io
  hookPhase: Running
  kind: Ingress
  message: ingress.networking.k8s.io/<APP_NAME> unchanged
  name: <APP_NAME>
  namespace: x
  status: Synced
  syncPhase: Sync
  version: v1

whereas in

.status.resources

- group: extension
  health:
    message: Pending deletion
    status: Progressing
  kind: Ingress
  name: <APP_NAME>
  namespace: x
  requiresPrunning: true
  status: unknown
  version: v1beta1

Question

Why are the API version different between the .status.operationState.syncResult.resources and .status.resources ?

• Committed app manifests were in networking.k8s.io/v1
• we checked the exiting ingress object, which was also reported as networking.k8s.io/v1 by kubectl

Our hypothesis is that our current version of Argo-cd "finalizer" only supports this kind of "hard-coded" API version of the ingress and is stuck since it does not found the objects it is looking for with the strict API version. But more precision are welcome.

As a workaround, we manually delete the ingresses objects with the networking.k8s.io/v1 API version and everything ends ok.

In advance, many thanks for your time, help and explanations 🙏🏻
