Error: could not read valid configmap "istio" from namespace "istio-system": failed to convert to proto

Question

team, When i'm trying istio-0.3.0, get an error. Any tips? Thanks!

$ kubectl apply -f <(istioctl kube-inject -f myservice.yaml) Error: could not read valid configmap "istio" from namespace "istio- system": failed to convert to proto. unknown field "controlPlaneAuthPolicy" in istio_proxy_v1_config.ProxyConfig - Re-run kube-inject with-i and ensure valid MeshConfig exists error: no objects passed to apply ` But I checked, configmap is right there in namespace "istio-system"

$ kubectl get configmap -n istio-system NAME DATA AGE istio 1 2m istio-ingress-controller-leader-istio 0 2m istio-mixer 1 2m FYI, what i've done before that curl -L https://git.io/getLatestIstio | sh - cd istio-0.3.0 kubectl apply -f install/kubernetes/istio-auth.yaml namespace "istio-system" created clusterrole "istio-pilot-istio-system" created clusterrole "istio-initializer-istio-system" created clusterrole "istio-mixer-istio-system" created clusterrole "istio-ca-istio-system" created clusterrole "istio-sidecar-istio-system" created clusterrolebinding "istio-pilot-admin-role-binding-istio-system" created clusterrolebinding "istio-initializer-admin-role-binding-istio-system" created clusterrolebinding "istio-ca-role-binding-istio-system" created clusterrolebinding "istio-ingress-admin-role-binding-istio-system" created clusterrolebinding "istio-sidecar-role-binding-istio-system" created clusterrolebinding "istio-mixer-admin-role-binding-istio-system" created configmap "istio-mixer" created service "istio-mixer" created serviceaccount "istio-mixer-service-account" created deployment "istio-mixer" created customresourcedefinition "rules.config.istio.io" created customresourcedefinition "attributemanifests.config.istio.io" created customresourcedefinition "deniers.config.istio.io" created customresourcedefinition "listcheckers.config.istio.io" created customresourcedefinition "memquotas.config.istio.io" created customresourcedefinition "noops.config.istio.io" created customresourcedefinition "prometheuses.config.istio.io" created customresourcedefinition "stackdrivers.config.istio.io" created customresourcedefinition "statsds.config.istio.io" created customresourcedefinition "stdios.config.istio.io" created customresourcedefinition "svcctrls.config.istio.io" created customresourcedefinition "checknothings.config.istio.io" created customresourcedefinition "listentries.config.istio.io" created customresourcedefinition "logentries.config.istio.io" created customresourcedefinition "metrics.config.istio.io" created customresourcedefinition "quotas.config.istio.io" created customresourcedefinition "reportnothings.config.istio.io" created attributemanifest "istioproxy" created attributemanifest "kubernetes" created stdio "handler" created logentry "accesslog" created rule "stdio" created metric "requestcount" created metric "requestduration" created metric "requestsize" created metric "responsesize" created metric "tcpbytesent" created metric "tcpbytereceived" created prometheus "handler" created rule "promhttp" created rule "promtcp" created configmap "istio" created customresourcedefinition "destinationpolicies.config.istio.io" created customresourcedefinition "egressrules.config.istio.io" created customresourcedefinition "routerules.config.istio.io" created service "istio-pilot" created serviceaccount "istio-pilot-service-account" created deployment "istio-pilot" created service "istio-ingress" created serviceaccount "istio-ingress-service-account" created deployment "istio-ingress" created serviceaccount "istio-ca-service-account" created deployment "istio-ca" created

I am suspecting you once installed previous version of istio and thus your istioctl is still referring to the old one. To confirm this: does istioctl version prints out version 0.3.0?

getLatestIstio script does not install to your $PATH actually, it exists within istio-0.3.0/bin. Please run your command like kubectl apply -f <(./bin/istioctl kube-inject -f myservice.yaml).
