In this lesson, we’ll guide you through installing Istio on your Kubernetes cluster using the istioctl command-line tool. This tutorial focuses on using the demo profile, which is ideal for demonstrations and initial testing.

​
Step 1: Install Istio

Run the following command to install Istio using the demo profile:
After executing the command, you should see output resembling:
This output confirms that the essential Istio core components have been successfully installed and that the resources for Istiod are being processed.

​
Step 2: Verify the Istio Installation

Once the installation completes without any errors, several new resources—such as cluster roles, cluster role bindings, and custom resource definitions (CRDs)—will be present in your cluster. To ensure everything is set up correctly, run the following command:
You should receive output that confirms a single Istio control plane is detected along with successfully verified resources. For example:
Istio deploys three components along with 13 custom resource definitions during installation, confirming that your cluster is now fully equipped with the necessary Istio resources.
