make "charts" a helm/helmsman repo

[praveendhac]

The charts cannot be directly used with helm/helmsman. Need to make the charts directory a helm repo.

@praveendhac Do you have this working for any other Git repos? It looks like to me like it's meant to point to a charts repo, such as https://github.com/helm/chartmuseum (and not direct to a specific chart on Git...but I've only spent 2 mins having a look).

If not, try https://github.com/mintel/dex-k8s-authenticator/tree/master/charts/dex-k8s-authenticator as the URL. This repo has 2 charts (dex and dex-k8s-authenticator) - you would need to reference them independently.

[praveendhac]

The URL does not follow chart repository structure, https://github.com/helm/helm/blob/master/docs/chart_repository.md

That is for if you want to host your own charts repository, which is a collection of charts packaged up together with an index.html.

It's not related to how you structure a specific chart, which is what we provide - see https://docs.bitnami.com/kubernetes/how-to/create-your-first-helm-chart/ ).

[praveendhac]

Because of the missing index.yaml file, the repo cannot be used by helmsman. Has to convert the repo into helm repo and push to our local repo to use dex-k8s-authenticator/dex charts.

[nabadger]

The index.yaml links to the helm packages that are pre-built (tar.gz).

I'll take a look - I've found a few examples where people are doing this. It would however require us to pre-build the charts (but maybe that's a useful thing as you say).

@praveendhac Can you try this:

helm repo add mintel-dex https://raw.githubusercontent.com/mintel/dex-k8s-authenticator/feat-helm-repo/charts/repo/stable

Please note, this a branch feat-helm-repo that I've just pushed (so it's a test). If it works, I'll look to merge it to master.

Also note that I've re-structured the repo (added ./repo/stable for example)

[nabadger]

Note, if this is works, I'll probably add a mintel/charts repo so that any charts we develop and opensource can be available (rather than having the repo under mintel/dex-k8s-authenticator/charts

Closing due to inactively.
