I have created a private repository in Azure following this example: https://jessicadeen.com/how-to-create-a-public-helm-repo-using-azure-storage/. Everything worked fine, I was able to push my chart, add repository to my cluster and even to deploy it. In the next day I tried to upgrade my newly pushed chart which unfortunately isn't working anymore, it complains always with the generic error: Error: failed to download "azikiel/calendar" (hint: running "helm repo update" may help)
which is weird because I can see my new version of chart added to the cluster after repo update:
❯ helm search repo calendar
NAME CHART VERSION APP VERSION DESCRIPTION
azikiel/calendar 0.2.1 1.16.0 A Helm chart for KubernetesI remember that in the first time while deploying first version of my chart I haven't set up a SaS token or any other authentication method to pull it. Although I suspect that there was involved an environment variable which is missing in my new terminal session.
Please guide me on what is wrong in my setup.
The problem here was in the script that I created to push to Azure - it was corrupted. It was pushing index.yaml file so my repo new about new versions of my chart, but it was failing to push the chart itself to remote.
As per Vitalii's suggestion I was able to see that helm simply could not find that version of chart.
