Failed To Download Helm (hint Running Helm Repo Update May Help)

If you get the error Error: failed to download "stable/prometheus" (hint: running `helm repo update` may help) when executing this command, run helm repo update prometheus-community, and then try running the Step 2 command again.

Use the helm repo and helm search commands to list and search Helm repositories. helm search also enables you to find apps and repositories in Helm Hub.
When running the helm upgrade, it picks up my values.yaml and creates a /var/lib/grafana/dashboards/default directory, however the kubernetes.json it loads is empty, and I get the following error in the log;
I installed version 10 of the push command and make command worked fine creating the repos:
helm plugin install -push.git --version 0.10.0
I hope it's not an issue? Please let me know if anything has to be changed.
Thanks and Regards,

Thanks Simon for the kind words and the feedback. There is indeed a breaking change tracked by your issue which will be fixed soon. In the meantime, I took the opportunity to update this tutorial and its GitHub repository to now use `az acr helm push -u -p` without any `az login` prior that. Thanks!
Hi, I am trying to use Helm in CICD pipeline in Azure DevOps. I was going through lot of nice articles about this and this one is realy greate, but to be honest I am little bit confused about versioning of Helm package and push to repository with each build run. It means, that with each build I needs to push same version of Helm chart? Maybe only one change logically in appVersion have to be increased. For me it does not make sense, because in helm doc is written that version and appVersion are different properties. What is the best strategy for this? I am thinking about strategy to have just chart in specific version and use this exact same version until I will need to do changes in chart. Our infra is on Azure and Azure Devops. The most suitable use case for me is this one, but as I said the only one thinkg against to it is push helm chart for each build. Could you please help? I dont want to create some antipattern ?
Seems as though helm wants to deploy to localhost, is this correct, or have I made an error in the setting of some env variables? Everything seems to work,
I can access the ACR helm repo locally as well.
Hi Kwinten, glad you like it! For your error in CD, I would recommend trying to run the `az login` and `az aks get-credentials` commands locally with the associated variables values you are using in Azure DevOps. Those two commands will typically get the associated credentials in the `.kubeconfig` and will allow the `helm upgrade` command to reach out that remote server instead of localhost. Complementary to this in your Azure DevOps Pipeline (CD) you could add an extra variable `system.debug` to `false` to get more verbose info from within your Azure Pipeline Job run. Hope that helps, cheers!
Hi Sulaiman, the best way for you to debug this locally is to make sure to successfully run `az acr helm list` first and get the proper chart-name accordingly to then run your `az acr helm show` command. You could also follow our official docs around this -repos where you could also check that you are successfully able to login against that repo: either with `az login` or by using `-u -p` for the `az acr` sub-commands. Hope that helps!
Helm performs some strict version checks when performing any commands against the cluster and requires that the client have the same minor version as the tiller service (the helm component running in your cluster) in your Kubernetes cluster.
Since it is quite common to have different versions of Helm across your deployment workers or even across different environments clusters, this option lets you override the helm client tool that is invoked. By default, Octopus will expect the helm command to be directly available to the execution context. Provide either the explicit full path to the desired version of the helm tool or include a version of helm as a package. The available version can be downloaded via the helm public GitHub repository. Unlike some other Octopus steps like Azure Powershell Scripts, the helm client tools are not automatically embedded or installed by Octopus. This is due to the strict version requirements that would differ between Octopus Server installations, and the diverse number of different platform builds available.
Helm itself uses a client-server model. The helm command (the client) talks to the tiller (the server). The Helm client may interact with any number of different tiller services. In practice, there is a single tiller service running one Kubernetes cluster. This helps teams collaborate. It also means that Helm may run anywhere, such as on your CI servers or on your own computer. Tiller does the work to coordinate with Kubernetes and get the chart installed.
Publishing your chart involves three commands. The first command is helm package to generate a tar archive, followed by helm repo index to download an existing index.yml and merge it with the local chart. Then, it requires a command outside of Helm to upload the new index.yaml to the chart repository, and finally helm repo add to add your shiny new repo. This process is also covered in the official Chart Repository documentation.
