Before we move on to the installation of Istio, there are a few pre-installation tasks that we need to carry out. These include downloading the source code and validating the environment. We will learn how to carry out these tasks in this section.
Performing pre-installation tasks
Downloading the source code
We will be installing Istio in the istio-system namespace and will grant a cluster-admin role to it. This is just for convenience purposes and is not a requirement. The granular permissions, as per the Kubernetes administrator, can be applied to the required namespace for you to install Istio in your actual production environment.
You can download a specific version of Istio from https://github.com/istio/istio/releases...
