I am referring to the red alert shown in the docs of Istio / Istio Operator Install which says:
Prior to Istio 1.10.0, the namespace
istio-systemneeds to be created before installing the operator. As of Istio 1.10.0, this is no longer required.
Removed all istio namespaces from GKE cluster.
$ kubectl delete namespace istio-operator istio-system
Installed istioctl version 1.10.2 in MacOS following Istio / Using the Istioctl Command-line Tool.
Then ran the following:
$ istioctl operator dump > operator_dump.yaml $ kubectl apply -f operator_dump.yaml
Confirmed that the istio-operator is up & running
$ kubectl rollout status deployment/istio-operator -n=istio-operator deployment "istio-operator" successfully rolled out
The next step involves applying the IstioOperator CRD following the docs in Istio / Istio Operator Install
kubectl apply -f - <<EOF apiVersion: install.istio.io/v1alpha1 kind: IstioOperator metadata: namespace: istio-system name: example-istiocontrolplane spec: profile: demo EOF
At this point i expect it to just work. But i got the following error:
Error from server (NotFound): error when creating "STDIN": namespaces "istio-system" not found
This behavior does not align with the alert given in the same doc which says as of Istio 1.10.0, the namespace
istio-system no longer needs to be created beforehand
Can please help me understand the matter here. Or does the doc need revision?
