Allow to use helm.valuesObject and kustomize at the same time. Error: Manifest generation error (cached): multiple application sources defined: Kustomize, Helm

[gomin1d]

Summary

It is not possible to use helm.valuesObject and kustomize at the same time. If I try to do this, I get the error:

Failed to load target state: failed to generate manifest for source 1 of 2: rpc error: code = Unknown desc = Manifest generation error (cached): multiple application sources defined: Kustomize,Helm

Motivation

Here is my living example. I install helm chart mailu. I configured it via valuesObject. And also I want to configure tolerations and nodeSelector via kustomize.

apiVersion: argoproj.io/v1alpha1
kind: Application
metadata:
  name: mailu
  namespace: argocd
  finalizers:
    - resources-finalizer.argocd.argoproj.io
spec:
  project: default
  sources:
    - repoURL: https://mailu.github.io/helm-charts/

      chart: mailu
      kustomize:
        patches:

                path: /spec/template/spec
                value: 
                  tolerations:
                   - key: "host"
                     operator: "Equal"
                     value: "critical"
                     effect: "NoSchedule"
                  nodeSelector:
                   'kubernetes.io/hostname': 'dev.mineland.local'
      helm:

          persistence:

          clamav:

          redis:
            enabled: false

Proposal

Support simultaneous use of helm.valuesObject and kustomize at the same time. Or add the ability to change helm variables in kustomize.

Is there currently a workaround to this?

I think my preference would be that we add support for kustomization.yaml's helmCharts field by adding it to spec.source.kustomize. Then users can take advantage of the spec.source.kustomize.helmCharts[].valuesInline field.

@MartinLoeper yes, my solution: https://github.com/Mailu/helm-charts/issues/341#issuecomment-2089030963
