On a kubernetes cluster where I tried to uninstall istio control plane and it's operator and make sure they are not existing,
1.) I deployed istio CNI
cat <<EOF > istio-cni.yaml
apiVersion: install.istio.io/v1alpha1
kind: IstioOperator
spec:
components:
cni:
enabled: true
values:
cni:
excludeNamespaces:
- istio-system
- kube-system
logLevel: info
EOF
istioctl install -f istio-cni.yaml
2.) and install the operator
istioctl operator init
Upon checking the operator pod logs I can see:

One of my iop (from kubectl get iop -A
) have "policy" or "telemetry" fields which are no longer supported . So I need to delete them.
kubectl delete iop [iopname] -n istio-system
This get stucked though because my controller is already gone. So I have to do
kubectl edit iop [iopname] -n istio-system
istiooperators.install.istio.io
from the finalizer
After this I can see no error logs when I tried to install istio-CNI again followed by istioctl operator init
.
