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)

Istio is installed with Istio Ingress Gateway

• Kubernetes cluster version can be checked with the command:

  kubectl version --short | grep Server

  The output will be similar to the following:

  Server Version: v1.21.11-gke.1100

• Istio version can be checked in different ways, it is out of scope for this README. You can find more information here.

  The following command shows how to check version if Anthos Service Mesh is used:

  kubectl -n istio-system get pods -lapp=istiod -o=jsonpath='{.items[0].metadata.labels.istio\.io/rev}'

  The output will be similar to the following:

  asm-1132-5

It is possible to use other versions, but it hasn't been tested

This example describes installation in Development mode:

• In this mode helm chart is installed to the namespace not labeled with Istio.

  More information about labeling can be found here (Istio) or here (Anthos Service Mesh)

  You can find all labels for your namespace with the command:

  kubectl get namespace <namespace> -o jsonpath={.metadata.labels}

  The output shows that there are no any labels related to Istio:

  {"kubernetes.io/metadata.name":"default"}

  When the namespace is labeled with Istio, the output could be:

  {"istio-injection":"enabled","kubernetes.io/metadata.name":"default"}

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

  Helm version can be checked with the command:

  helm version --short

  The output will be similar to the following:

  v3.7.1+gd141386

• Kubectl (version: v1.21.0 or higher) kubectl

  Kubectl version can be checked with the command:

  kubectl version --short | grep Client

  The output will be similar to the following:

  Client Version: v1.21.0

Install the helm chart

Run this command from within this directory:

helm install gc-partition-deploy .

Uninstalling the Chart

To uninstall the helm deployment:

helm uninstall gc-partition-deploy

To delete secrets and PVCs:

kubectl delete secret --all; kubectl delete pvc --all
