Describe the bug

When installing a Helm chart that includes CRD's, the CRD's are not installed.

To Reproduce

Install the following application:

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: traefik
  namespace: argocd
  finalizers:
  - resources-finalizer.argocd.argoproj.io
spec:
  destination:
    namespace: argocd
    server: {{ .Values.clusterIP }}
  project: {{ .Values.project }}
  source:
    chart: traefik
    repoURL: https://containous.github.io/traefik-helm-chart
    targetRevision: 8.5.0
  syncPolicy:
    automated:
        prune: true

The installation fails because the CRD's are missing.

Expected behavior

The CRD's included in the chart are installed.

Facing the same issue. From what I gather, ArgoCD picks the helm version here: https://github.com/argoproj/argo-cd/blob/master/util/helm/helmver.go#L57

Also, traefik v2 helm chart from https://containous.github.io/traefik-helm-chart includes two apiVersion statements to declare both compatibility to helm 2 and helm 3. I am guessing this is the root cause.

Same problem here with Traefik. I might be overlooking something, but I'm not seeing the two apiVersion statements; I just see v1 here. Doesn't seem like an Argo CD problem to me. Just installing the CRDs separately from the chart in Argo CD for now. 🤷

[randrusiak]

I have the same problem. I guess it's caused because argo-cd uses helm template under the hood instead of install

@randrusiak - Please check if your Chart's apiVersion is v1. If so it has to be changed to apiVersion: v2 https://helm.sh/docs/topics/v2_v3_migration/

Thanks @ckeragala for pointing this out. Discovered your comment after hours of scratching my head over why CRDs from an upstream project weren't being deployed.

FYI to anyone with this issue in an upstream chart (off-the-shelf) you can place the manifest of your CRDs into the templates folder of your "chart" that is referencing the upstream as a workaround.

[mstrzele]

As a workaround, you can always force the application to use Helm v3 as it should handle the charts in both versions (apiVersion: v1 and apiVersion: v2).

apiVersion: argoproj.io/v1alpha1
kind: Application
# ...
spec:
  source:
    # ...
    helm:
      # ...
      version: v3
  # ...

I am still struggling with this and can't get past 3.2.x :/

Any advice?

In case you end up here you might have the same problem as me. Don't forget to whitelist the helm chart in the sourceRepos list in the AppProject!
