kubectl apply -f <(istioctl kube-inject -f book-info-v1.yaml)

error: no objects passed to apply

Answer 1

It probably means that istioctl kube-inject produced empty output in the istioctl kube-inject -f book-info-v1.yaml part. Try to run istioctl kube-inject -f book-info-v1.yaml as a separate command and see if it produces any errors.
