Deploy a chart with Flux on your Clustertool Cluster

This guide will explain briefly how to deploy a chart on your brand new Clustertool Cluster using Flux.

Create the files

Your charts can be placed in the folder clusters/main/kubernetes/apps/.
There will make a folder for your chart and inside that folder an app folder.
In this guide we will use as example librespeed
So it will be like: clusters/main/kubernetes/apps/librespeed/app/
In this folder we will create two files, helm-release.yaml and namespace.yaml.

apiVersion: v1
kind: Namespace
metadata:
  name: librespeed
## Add this part when you need a privileged namespace
#  labels:
#    pod-security.kubernetes.io/enforce: privileged

Privileged Namespace

Add the label for pod-security only when it is really needed. After deploying the chart and this part will be needed you will see this in your event logs.

apiVersion: helm.toolkit.fluxcd.io/v2
kind: HelmRelease
metadata:
  name: librespeed
  namespace: librespeed
spec:
  interval: 15m
  chart:
    spec:
      chart: librespeed
      version: 15.6.1
      sourceRef:
        kind: HelmRepository
        name: truecharts
        namespace: flux-system
      interval: 15m
  timeout: 20m
  maxHistory: 3
  driftDetection:
    mode: warn
  install:
    createNamespace: true
    remediation:
      retries: 3
  upgrade:
    cleanupOnFail: true
    remediation:
      retries: 3
  uninstall:
    keepHistory: false
  values:
    # Add here your chart specific values

Generate and deploy

Run clustertool genconfig. This will creates kustomization.yaml and ks.yaml files.
Also this will update the kustomization.yaml in the folder above.
Push to git
Wait for flux to get it deployed. This can be taken up to 30 minutes. Another option you can do is run flux reconcile or configure a flux webhook.
