In this article, we will explore how to install Istio on your Kubernetes cluster. There are three primary approaches:
  1. Using the Istioctl command-line utility.
  2. Deploying via an Istio operator.
  3. Installing with a Helm package.
For this guide, we will install Istio using Istioctl.

​
Installing Istio with Istioctl

To deploy Istio using Istioctl, execute the following command using the demo profile:
This command deploys a control plane component named Istiod in a new namespace (typically the Istio system namespace). In addition to Istiod — which includes key components such as Citadel, Pilot, and Galley — Istioctl deploys the Istio Ingress Gateway and the Istio Egress Gateway. Several Kubernetes service objects are also created to expose these services within your cluster.
Different profiles are available to suit various environments such as production or performance testing. For this demo, the demo profile is used.

​
Verifying the Istio Installation

Once the installation completes, verify that Istio has been correctly deployed by running:
This verification step confirms that Istio extends Kubernetes by adding custom resource definitions (CRDs) and deploying essential components into your cluster.
Stay tuned for the upcoming demo where we will show Istio in action and demonstrate its capabilities within your cluster.
