Install Istio:Part 2: Helm and Istio


This belongs to a 3 parts series on Installation of Istio. Before proceeding follow the previous steps in Part 1

We will use Helm to install Istio. So we need Helm first

Step 1: Install Helm

We will use homebrew to install Helm

brew install helm@3

brew install helm@3 command

Verify the installation. Execute helm version command.

If everything is fine, helm should be a recognised command and you should get the output like

helm version command output

Step 2: Install Istio

To understand what is Istio, refer my previous article on a dummies guide to Istio.

Before we install Istio, it is recommended by the official documentation to increase the laptop resources to 4 CPU cores and 8 GB memory.

Once you are done, let us go ahead and install Istio

  • Download the source and change directory

curl -L | ISTIO_VERSION=1.7.3 sh -

cd istio-1.7.3

  • Add the istioctl client to your path

export PATH=$PWD/bin:$PATH

  • Install Istio with the provided client, we will use the demo profile:

istioctl install — set profile=demo

On successful installation, you should see something like

Istio installed successfully

Step 3: Verify the installation

On the kube dashboard, you should see an istio-system namespace in the top dropdown

Visit url — http://localhost:8001/api/v1/namespaces/kubernetes-dashboard/services/https:kubernetes-dashboard:/proxy/#/overview?namespace=default

Here you can see the Istio components — Istiod, istio-egressgateway, istio-ingressgateway running.

Congratulation! Istio is finally installed.

Step 4: Install Prometheus (optional)

Istio data plane is responsible for collecting several metrics and passing them to the control plane. These metrics can be pushed into Prometheus which is a system for capturing events and alerts in real-time.

kubectl apply -f

Prometheus installation

Visit kube dashboard to verify the installation

Once you have done these steps, you may proceed to Part 3
