Unable to deploy helm charts via flux CD v2

Question

I am installing flux on AKS cluster and synch it with my private GitHub repo, not attached to organization to clearly narrow down if it is a certificates issue.

First thing first I performed is flux bootstrap! and it worked well. Unfortunately, when I try to create a flux binding to GitHub repo to install the helm chart then no fun.

flux bootstrap github --owner=$GITHUB_USER --repository=container-label-webhook --path=dev-cluster

✔ Kustomization reconciled successfully
► confirming components are healthy
✔ helm-controller: deployment ready
✔ kustomize-controller: deployment ready
✔ notification-controller: deployment ready
✔ source-controller: deployment ready
✔ all components are healthy

Now, I try to deploy my application by telling flux the location of my helm charts as like below:

flux create source helm label-webhook --url https://github.com/ameyaagashe/container-label-webhook/tree/main/chart --namespace label-webhook
✚ generating HelmRepository source
► applying HelmRepository source
✔ source created
◎ waiting for HelmRepository source reconciliation
✗ failed to fetch Helm repository index: failed to cache index to temporary file: failed to fetch https://github.com/ameyaagashe/container-label-webhook/tree/main/chart/index.yaml : 404 Not Found

Seeing the above failure I tried to grab some more information. But I am not able to understand what is the exact issue for the error message, no artifact for resource in storage

k get helmrepository -A

I appreciate the app I am trying to get deployed needs ca cert, key file and ca bundle so I tried with all those options as like below: I get the same X509 cert error even with Normal Github.com not the Enterprise one, this is crazy....

flux create source helm label-webhook --url https://github.com/ameyaagashe/container-label-webhook/tree/main/chart --namespace label-webhook --cert-file=./tls/label-webhook.pem --key-file=./tls/label-webhook-key.pem --ca-file=./tls/ca.pem

Anyone has deployed app via their private Github repo before?

It might be, that the error message is a bit misleading. Actually, if you authenticate to private repo there is a missing private key reference (or I don't see it in your example). Something like: flux create secret git podinfo-auth \ --url=ssh://git@github.com/stefanprodan/podinfo \ --private-key-file=./identity see: https://fluxcd.io/flux/components/source/gitrepositories/ — aholbreich, Jun 18 '23 at 16:08

I have, no issues. Follow instructions here https://www.opcito.com/blogs/creating-helm-repository-using-github-pages. You need to create the index file and get the correct url for you helm repository.
