using a vendor helm chart with flux

[bashfulrobot]

Hi there. In the sample docs, tutorials, etc, there are plenty of examples using a helm chart in a git repo.

When using a vendor helm repo that is something like:

helm repo add bitnami https://charts.bitnami.com/bitnami
helm install my-nginx bitnami/nginx

which URL would I use in the below code?

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: my-nginx
  namespace: nginx
spec:
  interval: 5m0s
  url: https://charts.bitnami.com/bitnami/???????

Would it literally be something like:

---
apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: my-nginx
  namespace: nginx
spec:
  interval: 5m0s
  url: https://charts.bitnami.com/bitnami/nginx

Or some other value I can grab from the index.yaml in the repo?

Thank you.

Please note that Bitnami moved to Docker Hub and you should be using an oci:// URL.

For an OCI repo it would be:

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: bitnami
  namespace: nginx
spec:
  interval: 12h
  type: oci
  url: oci://registry-1.docker.io/bitnamicharts # registry URL without the chart name

For a HTTP repo it would be:

apiVersion: source.toolkit.fluxcd.io/v1beta2
kind: HelmRepository
metadata:
  name: bitnami
  namespace: nginx
spec:
  interval: 50m
  url: https://charts.bitnami.com/bitnami # same URL as for "helm repo add"

The helm release:

helm install my-nginx bitnami/nginx

Translates to:

apiVersion: helm.toolkit.fluxcd.io/v2beta2
kind: HelmRelease
metadata:
  name: my-nginx
  namespace: nginx
spec:
  interval: 30m
  chart:
    spec:
      chart: nginx # no alias, just the chart name
      version: "*"
      sourceRef:
        kind: HelmRepository
        name: bitnami
      interval: 12h

Thank you so much! That helps clarify ton. I couldn't figure out how to select the chart itself. Bitnami was just simply a format example.

Thanks
