How to use HelmChart?

[AkashRajvanshi]

Hey, I'm a beginner-level DevOps engineer. I currently understanding the CD part with flux-v2. My Qus is how should I deploy the HelmChart in my cluster?

I set up a pod into GitRepository

---
apiVersion: source.toolkit.fluxcd.io/v1beta1
kind: GitRepository
metadata:
  name: podinfo
  namespace: flux-system
spec:
  interval: 30s
  ref:
    branch: master
  url: https://github.com/stefanprodan/podinfo

$ kg gitrepo -n flux-system
NAMESPACE     NAME          URL                                               READY   STATUS                                                              AGE
flux-system   podinfo       https://github.com/stefanprodan/podinfo           True    Fetched revision: master/deadf87be8deefc43497241a046f1a37f23c6851   13h

Then I set up a helm chart from that GitRepository

---
apiVersion: source.toolkit.fluxcd.io/v1beta1
kind: HelmChart
metadata:
  name: podinfo-helm
  namespace: flux-system
spec:
  chart: ./charts/podinfo
  sourceRef:
    name: podinfo
    kind: GitRepository
  interval: 5m

$ kg hc -n flux-system
NAME                CHART              VERSION   SOURCE KIND      SOURCE NAME   READY   STATUS                                 AGE
podinfo-helm        ./charts/podinfo   *         GitRepository    podinfo       True    Fetched and packaged revision: 5.2.1   13h

Now, How can I create HelpRepo or HelmRelease with this chart?? Please guide me to the right steps If I'm doing wrong here?

The HelmChart is embedded into the HelmRelease, a bit like how a Pod template in K8s is embedded into a Deployment.

See https://fluxcd.io/docs/guides/helmreleases/#define-a-helm-release for more information.

Thank You! Now I understand the concept of HelmChart

apiVersion: helm.toolkit.fluxcd.io/v2beta1
kind: HelmRelease
metadata:
  name: podinfo
  namespace: default
spec:
  interval: 5m
  chart:
    spec:
      chart: ./charts/podinfo
      sourceRef:
        kind: GitRepository
        name: podinfo
        namespace: flux-system
      interval: 1m
