Introduction
This chart bootstraps a deployment on a Kubernetes cluster using Helm package manager.
Prerequisites
The code was tested on Kubernetes cluster (v1.21.11) with Istio (1.12.6)
It is possible to use other versions, but it hasn't been tested
Operation system
The code works in Debian-based Linux (Debian 10 and Ubuntu 20.04) and Windows WSL 2. Also, it works but is not guaranteed in Google Cloud Shell. All other operating systems, including macOS, are not verified and supported.
