gistfile1.txt

1. setup

    ```console
    $ kind create cluster
    ```

1. install zot with minimal image for security-minded dist-spec-only

    ```console
    $ helm upgrade zot zot/zot --set image.repository=ghcr.io/project-zot/zot-minimal-linux-amd64
    ```

1. port-forward service for ease

    ```console
    $ kubectl port-forward svc/zot 50000:5000
    ```

1. Test pushing a bare helm chart to zot

    ```console
    $ helm create foo && helm package foo
    $ helm push foo-0.1.0.tgz oci://127.0.0.1:50000
    ```

1. Inspect OCI package with Skopeo

    ```console
    $ skopeo inspect --raw --tls-verify=false docker://127.0.0.1:50000/foo:0.1.0 | jq
    {
      "schemaVersion": 2,
      "config": {
        "mediaType": "application/vnd.cncf.helm.config.v1+json",
        "digest": "sha256:af9c03c64b1d3d1c76a09d75faf3fd1c8b9ccc97ce0d31e464bccf68fe236674",
        "size": 137
      },
      "layers": [
        {
          "mediaType": "application/vnd.cncf.helm.chart.content.v1.tar+gzip",
          "digest": "sha256:dce0001b81ca61d8710bce34361bdfc05748459adf008a101126508fb7e05309",
          "size": 3750
        }
      ]
    }
    ```

1.  Cleanup


    ```console
    $ kind delete cluster
    ```
