What's the index URL for Helm charts added to ACR?

Question

I'm following this guide on how to "Push and pull Helm charts to an Azure container registry".

So I've pushed a chart to ACR. I can see that it's there, both via the Azure UI and

az acr repository show \
  --name mycontainerregistry \
  --repository helm/hello-world

Is there a repository URL that I can use to configure others (in this case Flux v2) to pull charts from? I thought it might be https://mycontainerregistry.azurecr.io/helm/v1/repo/index.yaml, but it doesn't list the chart that I pushed.

What do I have to do to add my charts to the index.yaml, or should I use another URL?

Edit

I just realized that https://mycontainerregistry.azurecr.io/helm/v1/repo/index.yaml will show the charts pushed via az acr helm push commands. So maybe that URL is something else?

Answer 1

Actually, you can use the command helm repo add to add the Azure Container Registry as a repository to the helm, and then you can pull the charts from the ACR. And all the charts in the ACR named myacr.azurecr.io/helm/chartname and it means you will pull the charts from the ACR. The name decides where the chart pulls from.

For example, you add a repo with the command here:

helm repo add technosophos https://technosophos.github.io/tscharts

and you can show the repo like this:

then you can pull charts from this repo:

You can do the things like this with ACR. And helm will help you update the index of the repo. You don't need to do it yourself.

Answer 2

I used the following command and it works:

helm repo add YOUR_ACR_NAME https://YOUR_ACR_NAME.azurecr.io/helm/v1/repo  --username YOUR_ACR_NAME --password YOUR_ACR_PASSWORD

The result will be something like:

"YOUR_ACR_NAME " has been added to your repositories

The problem is, after this I still cannot find all helm charts I added by "az acr helm push". So sad.
