{{ Succinctly describe the bug }}

Im trying to install istio (current versio 1.0.5) on fresh kubernetes installation.

curl -L https://git.io/getLatestIstio | sh -
ISTIO_VERSION=$(ls | grep istio- )
cd $ISTIO_VERSION
helm install install/kubernetes/helm/istio --name istio --namespace istio-system

Im gettin g error:

Error: release istio failed: customresourcedefinitions.apiextensions.k8s.io "noops.config.istio.io" already exists

I've tested it many times on fresh Kubernetes.

If I run : kubectl apply -f install/kubernetes/istio-demo.yaml it works fine.

I have problem with helm only.
