Local minimal istio setup ready for apps to be installed

istio-local-setup

Local minimal istio setup ready for apps to be installed and smoke tested. You can replace helloworld with any app you wish.

Prerequisites

• Docker (tested with 8GB of RAM / 4 CPU's assigned)
• Kubernetes
  • You may use any Kubernetes setup you have e.g. MiniKube, Docker or even real hardware. Up to you. kubectl config get-contexts must point to your Kubernetes cluster. Here is a tested configuration using Kubernetes using docker only and WSL on Windows
• Helm
