`kubernetesconfiguration` resource version `v1api20241101` gets rollback to `v1api20230501`

[arnaud-tincelin]

Describe the bug

I am applying a FluxConfiguration version kubernetesconfiguration.azure.com/v1api20241101

The resource gets created normally:

fluxconfiguration.kubernetesconfiguration.azure.com/config2 created

However, when I read the resource in the cluster, the resource version has changed (note the kubectl.kubernetes.io/last-applied-configuration annotation) :

apiVersion: kubernetesconfiguration.azure.com/v1api20230501
kind: FluxConfiguration
metadata:
  annotations:
    kubectl.kubernetes.io/last-applied-configuration: |
      {"apiVersion":"kubernetesconfiguration.azure.com/v1api20241101","kind":"FluxConfiguration","metadata":{"annotations":{},"name":"config2","namespace":"cluster-config"},"spec":{"azureName":"config2","gitRepository":{"provider":"Azure","repositoryRef":{"branch":"demo"},"syncIntervalInSeconds":300,"url":"https://dev.azure.com/<organization>/<project>/_git/<repository>"},"kustomizations":{"tool":{"path":"./dev","prune":true,"retryIntervalInSeconds":120,"syncIntervalInSeconds":300,"timeoutInSeconds":300}},"namespace":"test","owner":{"armId":"/subscriptions/<sub-id>/resourceGroups/<rg-name>/providers/Microsoft.ContainerService/managedClusters/<cluster-name>"},"scope":"namespace","sourceKind":"GitRepository"}}
    serviceoperator.azure.com/latest-reconciled-generation: "1"
    serviceoperator.azure.com/operator-namespace: azure-service-operator
    serviceoperator.azure.com/poller-resume-id: GenericClient.CreateOrUpdateByID
    serviceoperator.azure.com/poller-resume-token: '{"type":"GenericResource","token":{"asyncURL":"https://management.azure.com/subscriptions/<sub-id>/resourceGroups/rg-lzo-rib-dev-gwc-01-wrk-01/providers/Microsoft.ContainerService/ManagedClusters/<cluster-name>/providers/Microsoft.KubernetesConfiguration/fluxConfigurations/config2/operations/5fb38939-893d-4f84-b961-ab22691450d9?api-version=2024-11-01<...>"}}

Azure Service Operator Version: 2.13.0
AKS Version: 1.31.7

Expected behavior

I expect the resource version to remain unchanged and the field spec.gitRepository.provider as well

To Reproduce

Apply the following file:

apiVersion: kubernetesconfiguration.azure.com/v1api20241101
kind: FluxConfiguration
metadata:
  name: config2
  namespace: cluster-config
spec:
  azureName: config2
  gitRepository:
    provider: Azure
    repositoryRef:
      branch: demo
    syncIntervalInSeconds: 300
    url: https://dev.azure.com/<organization>/<project>/_git/<repository>
  kustomizations:
    tool:
      path: ./dev
      prune: true
      retryIntervalInSeconds: 120
      syncIntervalInSeconds: 300
      timeoutInSeconds: 300
  namespace: my-app
  owner:
    armId: /subscriptions/<sub-id>/resourceGroups/<rg-name>/providers/Microsoft.ContainerService/managedClusters/<cluster-name>
  scope: namespace
  sourceKind: GitRepository

We think you're running into the issue discussed in #4147.

The workaround is to do this:

users can work around this problem and specify the specific API version they'd like to use when getting the objects, with kubectl get virtualmachines.v1api20220301.compute.azure.com (specifying the APIVersion as part of the get command), but this is annoying.

We're planning on changing API versioning for new API versions to honor the correct naming pattern so that this issue doesn't continue to happen for new APIs (not sure when that change will land though).
