az acr helm repo login

Is your feature request related to a problem? Please describe. I would love an option to use my currently-configured azure service principal to authenticate to ACR for helm without having to manually pipe/handle/enter credentials.

Describe the solution you’d like I’d love the command az acr helm repo login

Describe alternatives you’ve considered

• Manual input, when at my terminal (doesn’t work for CI/CD)
• Environment variables

Both options require me to extract and flow permanent credentials.

Additional context It would greatly simplify the advice found here.

@yugangw-msft any update on this? Almost been a year, still looking for azure supported authentication flow with helm3.

@SteveLasker When i tested OCI charts there was two blockers.

1. helm (upgrade --)install myocirelease acrrepo/ocichart is not implemented. This is a user experience issue because it is a major workflow change, but more importantly is not compatible with tools like argocd and fluxcd.
2. OCI charts as a dependency, is missing from helm. Any non trivial chart have one or more dependencies, so we are unable to migrate from non-oci charts.

apiVersion: v2
name: mychart
version: 1.0.0
dependencies:
- name: ocichart
  version 1.0.0
  repository: acrrepo.azure.io/myocichartdependency

I know it is being worked on and will be available in the future. But in my opinion without these features ready, it is somewhat premature to steer everyone towards using OCI charts and deprecating/removing the old workflow. Although I am talking about core Helm features, it has an impact on how to consume helm charts from the acr registry. I hope that helps.
