-When using aad-pod-identity to enable access to ACR, add the following patch to
-your bootstrap repository, in the `flux-system/kustomization.yaml` file:
-
-```yaml
-apiVersion: kustomize.config.k8s.io/v1beta1
-kind: Kustomization
-resources:
-  - gotk-components.yaml
-  - gotk-sync.yaml
-patches:

-When using pod-managed identity on an AKS cluster, AAD Pod Identity
-has to be used to give the `image-reflector-controller` pod access to the ACR.
-To do this, you have to install `aad-pod-identity` on your cluster, create a
-managed identity that has access to the container registry (this can also be the
-Kubelet identity if it has `AcrPull` role assignment on the ACR), create an
-`AzureIdentity` and `AzureIdentityBinding` that describe the managed identity
-and then label the `image-reflector-controller` pods with the name of the
-AzureIdentity as shown in the patch above. Please take a look at
-[this guide](https://azure.github.io/aad-pod-identity/docs/) or
-[this one](https://docs.microsoft.com/en-us/azure/aks/use-azure-ad-pod-identity)
