Make GitHub repo directly useable from Helm

[hazcod]

Hi,
Until this is added to the official helm packages, it might be nice to have the helm Chart useable via this git repo as a helm repo?
I would like to install this using my terraform helm provider.
e.g. this should exist: https://raw.githubusercontent.com/netdata/helmchart/master/index.yaml

Ref #72

Another possibility is creating releases with .tar.gz archives so we can directly refer those.

[ncmans]

Definitely doable with something like Github pages. @cakrit what do you think? After Helm 3 release, helm stable is not longer accepting new charts. Instead Helm Hub accepts inclusion of repositories which it then searches across.

[cakrit]

Don't ask for my permission gents, go ahead! :)

@hazcod Please put up a PR, I will happily review it!

@prologic
Here's my proposal on how we should do it (which applies to any helm chart for that matter):

1. Setup gh-pages as helm chart repo (ie create the branch and add some Readme) — this is the branch we will auto-update with new packaged releases of helm chart.
2. Build a CI pipeline that upon release tagging (ie git tag v1.0.5):
   a. Packages the helm chart (ie helm package ...)
   b. Creates a github release and uploads the packaged tarball as an asset.
   c. Updates the helm repo index on gh-pages branch (ie helm repo index) pointing to the correct github URL for the package.
   d. Pushes the gh-pages branch with the updated index.yaml (and maybe a changelog).

[prologic]

@ncmans Okay sounds good to me :) The gh-pages parts I already know quite well; so thanks for the helm hints. I guess @Ferroin and I should do this unless the OP is still interested :)

[hazcod]

Would love to, but i’m afraid i’m a bit too fresh to the Helm scene. 😄 appreciate the work!

[prologic]

@knatsakis I think I've seen some PRs from you that are making this "in progress"? Added you as assigner and marked appropriately :)

[knatsakis]

@hazcod, @prologic a helm repo has been created at https://netdata.github.io/helmchart/

It has the bare minimum at the moment, and only includes the 3 latest versions of the helm chart. We have to manually update it for the time being. But it is usable from the terraform helm provider.

I will keep updating this issue with progress on this front.

[knatsakis]

Todo:

• Update documentation regarding the helm repo and in the helm repo itself.
• Automate updates to the helm repo as @ncmans described.

[prologic]

As a first step I would just create the CI workflow that implements what @MansM originally suggested and go from there. We can then "automate" this entirely once we figure out where it all fits in the greater schemes of things.

We can just manually trigger the workflow from dispatc_event(s) for now...

Hi any progress...?

[prologic]

None yet, hasn't been picked up from our Backlog. If you'd like to help I would be able to help you and get reviews done!

[fzyzcjy]

@prologic I will try to do that when having free time :)

[kam1kaze]

Hey folks. I suggest to update README.md file with HELM repo information, bcz I accidentally found it when I switched to gh-pages branch. It has existed for 6 months! :)

[odyslam]

Thanks @kam1kaze for the suggestion. One of our engineers will respond promptly!
Take care :)

[prologic]

Hey @kam1kaze Its on my immediate backlog to get back to. I plan to complete this this week. Thanks for pining this!

Would love to see it completed.

[odyslam]

@milindchawre

Thanks for the feedback! It's so important to us.

P.S

Welcome to our community :)

[milindchawre]

Thanks @odyslam
Actually my plan was to add netdata in civo marketplace. By looking at its current installation steps, I decided to wait until this is fixed.

[prologic]

This is ready now and awaiting review #152 and #153

[milindchawre]

@prologic Is it done? I don't see new installation steps in the README.md file.

[knatsakis]

Hi @milindchawre.

This is done, indeed. Kindly find the instructions here: https://netdata.github.io/helmchart/. #163 should also add a pointer to this in README.md.

[milindchawre]

Thanks @knatsakis for pointing it out.

[kam1kaze]

@knatsakis @prologic the instruction from https://netdata.github.io/helmchart/ doesn't work :)

$ helm repo add netdata https://helm.my-netdata.io/
$ helm install netdata

Domain helm.my-netdata.io could not be resolved:

[knatsakis]

Oh, sorry about that.

The correct command is:

helm repo add netdata https://netdata.github.io/helmchart/

(Fixed by #168)
