Installing Istio with Helm via helm template

1. Create a namespace for the 1istio-system1 components:

kubectl create namespace istio-system

2. Install all the Istio Custom Resource Definitions (CRDs) using kubectl apply, and wait a few seconds for the CRDs to be committed in the Kubernetes API-server:

helm template install/kubernetes/helm/istio-init --name istio-init --namespace istio-system | kubectl apply -f -

3. Verify that all 53 Istio CRDs were committed to the Kubernetes api-server using the following command:

   If cert-manager is enabled, then the CRD count will be 58 instead.

kubectl get crds | grep 'istio.io\|certmanager.k8s.io' | wc -l

4. Select a configuration profile and then render and apply Istio’s core components corresponding to your chosen profile.

helm template install/kubernetes/helm/istio --name=istio --namespace=istio-system --values=/path/to/values.yaml | kubectl apply -f -
