Flux OCI with kubernetes on Azure

Question

I have switched from using tradition way of pushing helm chart to oci format.

But on then kubernetes cluster the charts are not getting installed and I am getting the below error:

chart pull error: chart pull error: failed to download chart for remote reference: temp.azurecr.io/helm/v1/repo/abc:1.0.1: not found
chart pull error: chart pull error: failed to download chart for remote reference:

My new repository is :

oci://abc.azurecr.io/charts

instead of

https://abc.azurecr.io/helm/v1

Also In kubernetes cluster the helm path is not getting updated to charts, I am not sure why it is still poiting to

/helm/v1 path

Answer 1

I tried to reproduce the same issue in my environment and got the below output

I have enabled the OCI experimental support for helm versions

export HELM_EXPERIMENTAL_OCI=1
helm version

I have created the container registry

I have created the sample chat and saved the chart into the local archive

cd .. 
helm package .

I have given the some registry credentials and also created the service principal using this link

I have logged into the registry using below command

helm registry login Registry_name.azurecr.io

we have to give the username and password of the registry

I run the helm push command to push the chart to registry as a OCI format

helm push hello-world-0.1.0.tgz oci://registry_name.azurecr.io/helm

I have used the below command to show the properties of the repository

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

To check the data stored in the repository

az acr manifest list-metadata \
  --registry myregistry890 \
  --name helm/hello-world

I have pulled the chat using below command

helm pull oci://repository_name.azurecr.io/helm/hello-world --version 0.1.0
