What is Istio

Istio is an open-source service mesh that provides a uniform way to manage, connect, and secure microservices. It helps to manage traffic, enhance security capabilities, and provide telemetry data for understanding service behavior. Read the Istio documentation to learn more.

Prerequisites

• Access to a Kubernetes (v1.24 or higher) cluster

Procedure

1. Create the kyma-system namespace and label it with istio-injection=enabled:

   kubectl create namespace kyma-system
   kubectl label namespace kyma-system istio-injection=enabled --overwrite

2. To install Istio, you must install the latest version of Kyma Istio Operator and Istio CRD first. In order to install the standard version, run :
