Deploy helm chart

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.

Packages

Packages are only needed for installation from a local computer.

• HELM (version: v3.7.1 or higher) helm
• Kubectl (version: v1.21.0 or higher) kubectl
