# Istio testing

## 1. Create cluster

```bash

kind create cluster -n istio --config 0-kind-cluster.yaml

```

## 2. Install ingress controller

```bash

# source: https://raw.githubusercontent.com/kubernetes/ingress-nginx/main/deploy/static/provider/kind/deploy.yaml

kubectl apply -f 1-ingress-nginx.yaml

```

Wait until is ready to process requests running:

```bash

kubectl wait --namespace ingress-nginx \

  --for=condition=ready pod \

  --selector=app.kubernetes.io/component=controller \

  --timeout=90s

```

Test ingress controller:

```bash

kubectl apply -f 2-ingress-test.yaml

#  then open browser and go to http://localhost/foo/hostname or http://localhost/bar/hostname

```

## 3. Install istio

```bash

istioctl install --set profile=demo -y

```

Enable namespace auto-injection:

```bash

kubectl label namespace default istio-injection=enabled

```

> Expose istio-ingressgateway with ingress. This would simulate the real world scenario where the ingress controller is used to expose the services and the istio-ingressgateway is used to route the traffic to the services.

```bash

kubectl apply -f 5-istio-ingress.yaml

```

## 4. Install addons

```bash

kubectl apply -f 6-addons

```

show kiali dashboard:

```bash

istioctl dashboard kiali

```

> same for grafana, jaeger, prometheus, etc.
