cert-manager install issues with flux2

[dev-samples]

I have successfully bootstrapped flux into a v1.17.13 k8s cluster:

$ kubectl get pods
NAME                                      READY   STATUS    RESTARTS   AGE
helm-controller-996df94bbcc-tglj6          1/1     Running   0          130m
kustomize-controller-99df53296-s624g      1/1     Running   0          130m
notification-controller-71dcddfc7-lthx5   1/1     Running   0          130m
source-controller-85p44bc47b-z5cqq        1/1     Running   0          130m

Based on:
https://github.com/fluxcd/flux2-kustomize-helm-example
https://github.com/equinor/sdp-flux/blob/prod/base/standalone-components/cert-manager/helm-release.yaml

I am trying to deploy cert-manager into my cluster having this setup:

├── clusters
│   └── my-cluster
│       ├── flux-system
│       │   ├── gotk-components.yaml
│       │   ├── gotk-sync.yaml

Where:

  - release.yaml

    ingressShim:

After I have pushed the above its successfully picked up by flux/kustomize-controller but I get the following errors:

kubectl logs -f kustomize-controller-88df54496-s620g

Apparently name, repository and version are not known and it says spec is missing - which its not.

Any suggestions?

Fyi; I have managed to install nginx with similar approach so it must be something specific for the cert-manager chart?

chart.spec is missing, check out the docs on how a HelmRelease looks in v2: https://toolkit.fluxcd.io/guides/helmreleases/
