Config kubeconfig (Or skip)

For Mac

TOKEN=$(kubectl -n kube-system describe secret default| awk '$1=="token:"{print $2}')
kubectl config set-credentials docker-for-desktop --token="${TOKEN}"

For Windows

$TOKEN=((kubectl -n kube-system describe secret default | Select-String "token:") -split " +")[1]
kubectl config set-credentials docker-for-desktop --token="${TOKEN}"

# update charts repo (Optional)
helm repo update

For Windows

# Use Chocolatey on Windows
# NOTE: please ensure you can access googleapis
choco install kubernetes-helm

helm init --upgrade -i registry.cn-hangzhou.aliyuncs.com/google_containers/tiller:v2.14.1 --skip-refresh

# update charts repo (Optional)
helm repo update

Install Istio

More details can be found in https://istio.io/docs/setup/kubernetes/

Download Istio 1.2.2 and install CLI

curl -L https://git.io/getLatestIstio | ISTIO_VERSION=1.2.2 sh -
cd istio-1.2.2/
export PATH=$PWD/bin:$PATH

Install Istio with Helm chart

# Install the istio-init chart to bootstrap all the Istio’s CRDs
helm install install/kubernetes/helm/istio-init --name istio-init --namespace istio-system

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

# Install the istio chart
helm install install/kubernetes/helm/istio --name istio --namespace istio-system

Check status of istio release

helm status istio

Enable automatic sidecar injection for default namespace

kubectl label namespace default istio-injection=enabled
kubectl get namespace -L istio-injection

Install Book Info sample

kubectl apply -f samples/bookinfo/platform/kube/bookinfo.yaml
kubectl apply -f samples/bookinfo/networking/bookinfo-gateway.yaml


Confirm application is running
