Install Istio

We will install all the Istio components using the built-in demo configuration profile. This installation lets you quickly get started evaluating Istio.

The demo configuration profile is not suitable for performance evaluation. It is designed to showcase Istio functionality with high levels of tracing and access logging. For more information about Istio profile, click here.

Istio will be installed in the istio-system namespace.

yes | istioctl manifest apply --set profile=demo
