Set chart version to application version

[onedr0p]

Hi 👋🏼

It would be great for automation purposes if the version of the chart matched the version of the application. I deployed the helm chart with installCRDs: false. I am installing CRDs via a GitRepository and a Fluxtomization so the helm chart and crds versions can be managed by Renovate.

The reason for doing this is so I can contain the HelmRelease and Terraform CRs in the same Fluxtomization.

In simplest terms if you try to apply the following Kustomization for the first time it will fail because the CRDs are not installed yet and I want a automated way to manage versions of the CRDs and Helm Chart in a single Fluxtomization.

# ./kustomization.yaml
---
apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
resources:
  - helm-release.yaml
  - terraforms.yaml

---

# ./helm-release.yaml
---
apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: tf-controller
  namespace: flux-system
spec:
  interval: 15m
  chart:
    spec:
      chart: tf-controller
      version: v0.13.1
      sourceRef:
        kind: GitRepository
        name: tf-controller
        namespace: flux-system
  install:
    createNamespace: true
    remediation:
      retries: 5
  upgrade:
    remediation:
      retries: 5
  values:
    installCRDs: true

---

# ./terraforms.yaml
---
apiVersion: infra.contrib.fluxcd.io/v1alpha1
kind: Terraform
metadata:
  name: cloudflare
  namespace: flux-system
spec:
  approvePlan: auto
  interval: 12h
  path: ./terraform/cloudflare
  sourceRef:
    kind: OCIRepository
    name: terraform-cloudflare-oci
    namespace: flux-system
  backendConfig:
    disable: true
  cliConfigSecretRef:
    name: tfe-cli-config
  varsFrom:
    - kind: Secret
      name: cloudflare-vars
  writeOutputsToSecret:
    name: cloudflare-outputs

An full example can be seen here with Kyverno:

• Kyverno GitRepository and the Fluxtomization applying their CRDs.

• The apps Fluxtomization which under it has Kyverno CRs and the Kyverno HelmRelease.

• The Kyverno HelmRelease and the CRs which are all under the same apps Fluxtomization

• The pull request where you can see the versions being updated on a new release.

Thanks!

Thank you so much @onedr0p for bringing this topic up.

We discussed about this a couple months ago and I think it's a good idea to bring it up again.

I am personally feeling that it's a bit hard to troubleshoot problems for users too with the current chart versioning.

Sounds good! It was probably a good idea to keep separate versions until the helm chart became stable. If you don't see yourself making any drastic changes to the helm chart it would be nice to roll them under the same version as the app.
