Installing Istio

Before you continue, make sure you have a running Kubernetes cluster. You can run kubectl cluster-info to check everything is good.

  1. Download the latest Istio (1.4.3):
curl -L https://git.io/getLatestIstio | sh -
  1. Ensure you can install Istio by running the pre-check command:
istioctl verify-install

  1. In the terminal/console, open the istio-1.4.3 folder (or the folder where you downloaded/extracted the Istio to).

  2. Install the demo profile of Istio:

    istioctl manifest apply --set profile=demo

  3. Verify the installation/wait for all pods to be in the Running state:

    $ kubectl get pods -n istio-system

Once you see output similar to the one above, you have successfully installed Istio on your Kubernetes cluster. Next, we are going to label the default namespace, so anything we deploy in that namespace will have the Envoy proxy automatically injected:

kubectl label namespace default istio-injection=enabled

Uninstalling Istio

To remove all Istio resources installed on the cluster, run:

istioctl manifest generate --set profile=demo | kubectl delete -f -

What next?

Now that you have everything set up, you can continue with the exercises below:
