I see it’s possible to disable installation of prometheus when using the Istio helm chart.
I can’t find how to do the same when using the Istio standalone operator.
I also tried the applying the following (disabling telemetry, see https://istio.io/docs/setup/install/standalone-operator/#update):
kubectl apply -f - <<EOF
apiVersion: install.istio.io/v1alpha2
kind: IstioControlPlane
metadata:
namespace: istio-operator
name: example-istiocontrolplane
spec:
profile: default
telemetry:
enabled: false
EOF
But still prometheus is enabled.
