Helm chart on Kubeapps is not available

[maurizio-lattuada]

In README.md is suggested to download Chaoskube's Helm chart from Kubeapps. Unfortunately, the chart there cannot be found: the HTTP GET https://hub.kubeapps.com/api/chartsvc/v1/charts/stable/chaoskube returns a 404 there.

Would it be possible for you to check whether the Helm chart is still published there? The old repository https://github.com/helm/charts/tree/master/stable/chaoskube is now in archived state since end November.

Thank you

same here. also any helm 3 version ?

[javajon]

This Katacoda scenario that teaches chaoskube as well as this scenario at O'Reilly learning relies on the Helm chart. These scenarios will be updated/fixed as soon as the new chart location is made available.

Unfortunately I've the same issue here. Probably submitting the chart to the kuebapps Hub would be a good idea. I can help out with this if there is something missing which is "required" by the best practices of kubeapps Hub.

The stable chart repository maintainer by Helm has been deprecated so that might be it. Is there an official Helm chart for Chaoskube?

[ghouscht]

I don't think so, no. But why not create one now? I can file a PR with the chart if @linki is ok with merging it.

[WyriHaximus]

That's the thing I was hinting at 👍 . Happy to help out

FYI: The PR was merged, you can now use the helm chart with:

helm repo add chaoskube https://linki.github.io/chaoskube
helm repo update
helm template chaoskube/chaoskube

Perfect, thank you all for this wonderful outcome 👍

Tried this:

kubectl create namespace chaoskube

helm repo add chaoskube https://linki.github.io/chaoskube

helm repo update

helm install chaoskube chaoskube/chaoskube \
  --version 0.1.0 \
  --namespace chaoskube \
  --set 'tag=v0.21.0' \
  --set 'namespaces=!kube-system' \
  --set labels=app-purpose=chaos \
  --set interval=20s

Got this:

The Issue is image tag in repo is prefixed with "v" and this line strips the "v":

image: "{{ .Values.image.repository }}:{{ .Values.image.tag | default .Chart.AppVersion }}"

Also,

In value.yaml, the default for "tag" should be "latest", not "":

# Overrides the image tag whose default is the chart appVersion.
  tag: "latest"

Also, as part of the new chart for the merge, the install instructions in the README should have new Helm instructions.

Also, chart version number went from 3.3.2 backwards to 0.1.0. Suggest the new chart to be 4.0.0, bump major number since most of the chart values are different.

@javajon Thanks for trying and reporting this.

@javajon I added a PR that fixed it for me: #324

I don't think we should add tag: "latest" to the default values.yaml. This is only for when you want to override the default version defined in the Chart.yaml with something else. Let me know what you think about it.
