Error when fetching helm chart with 'kustomize build --enable-helm'

[4x3lpri3t0]

Describe the bug

When using a HelmChartInflationGenerator, kustomize fails with the following command:

$ kustomize build --enable-helm

The output is the following:

Error: Error: looks like "oci://f1dev.azurecr.io/helm/f1" is not a valid chart repository or cannot be reached: object required
: unable to run:

'helm pull --untar --untardir /opt/HutchMaster/SharedServer/k8s/f1/kustomize-overlays/dev/we/charts --repo oci://f1dev.azurecr.io/helm/f1 f1 --version 0.1.0'

with env=[HELM_CONFIG_HOME=/var/folders/7q/d7z7scm55kz3jtcwwzdql2m40000gn/T/kustomize-helm-1630665907/helm HELM_CACHE_HOME=/var/folders/7q/d7z7scm55kz3jtcwwzdql2m40000gn/T/kustomize-helm-1630665907/helm/.cache HELM_DATA_HOME=/var/folders/7q/d7z7scm55kz3jtcwwzdql2m40000gn/T/kustomize-helm-1630665907/helm/.data] (is 'helm' installed?)

I can confirm that I get the same error when using helm directly:

helm pull --untar --untardir /opt/HutchMaster/SharedServer/k8s/f1/kustomize-overlays/dev/we/charts --repo oci://f1dev.azurecr.io/helm/f1 f1 --version 0.1.0

Same output as before:

Error: Error: looks like "oci://f1dev.azurecr.io/helm/f1" is not a valid chart repository or cannot be reached: object required

However, when running that very same command but without (!) the --repo flag... it works!

helm pull --untar --untardir /opt/HutchMaster/SharedServer/k8s/f1/kustomize-overlays/dev/we/charts oci://f1dev.azurecr.io/helm/f1 f1 --version 0.1.0

Output:

Pulled: f1dev.azurecr.io/helm/f1:0.1.0

Files that can reproduce the issue

kustomization.yaml:

apiVersion: kustomize.config.k8s.io/v1beta1
kind: Kustomization
generators:
- chartInflator.yaml

chartInflator.yaml:

apiVersion: builtin
kind: HelmChartInflationGenerator
metadata:
  name: f1

# URL to the Repo
repo: "oci://f1dev.azurecr.io/helm/f1"

# The name of the chart to use
name: f1
version: 0.1.0

# Path to a values.yaml
valuesFile: kustom-values.yaml

# The name of the release
releaseName: f1dev
# Namespace to deploy to
releaseNamespace: f1

Expected output

The kustomize kustomize --enable-helm command that internally builds this helm command

helm pull --untar --untardir /opt/HutchMaster/SharedServer/k8s/f1/kustomize-overlays/dev/we/charts --repo oci://f1dev.azurecr.io/helm/f1 f1 --version 0.1.0

should be actually building it without the --repo flag:

helm pull --untar --untardir /opt/HutchMaster/SharedServer/k8s/f1/kustomize-overlays/dev/we/charts oci://f1dev.azurecr.io/helm/f1 f1 --version 0.1.0

then it works :)

Actual output

Error: Error: looks like "oci://f1dev.azurecr.io/helm/f1" is not a valid chart repository or cannot be reached: object required
