When using AWS/GCP KMS, you'll have to bind an IAM Role
with read access to the KMS keys to the `default` service account of the
`flux-system` namespace for kustomize-controller to be able to fetch

[Service Principal credentials as environment variables](https://github.com/mozilla/sops#encrypting-using-azure-key-vault)
or with [add-pod-identity](https://github.com/Azure/aad-pod-identity).
