• If the current behavior is a bug, please provide parameters either in plain text or with a screenshot

• command: repo

• params: add rook-master https://charts.rook.io/master

• What is the expected behavior? I'm expecting this tu succeed the same way it would from my cmdline

• What is the motivation / use case for changing the behavior? Keeps failing, where it shouldn't

• Please tell us about your environment and the type of VSTS agent pool you're running the Helm task in:

  • [ ] Hosted MacOS

• Other information (e.g. detailed explanation, stacktraces, related issues, suggestions how to fix, links for us to have context, eg. stackoverflow, gitter, etc)

Helm by default writes this information to ~/.helm/repository/repositories.yaml. This directory is likely restricted on the shared build agents. The Helm client will respect the HELM_HOME environment variable so try setting this to a location that is accessible (such as $(System.DefaultWorkingDirectory)). Keep in mind that this state will likely not persist between builds.

Hi,

I've added a preceeding bash step, which would export HELM_HOME=$(System.DefaultWorkingDirectory) however the error persists.

Either I'm doing something wrong, or this issue is not related to HELM_HOME (I've got a preceeding helm init step and it works fine - for what it's worth).

[mmisztal1980]

I've modified the bash task to do the following:

Task Inline Bash

# Write your commands here
export HELM_HOME=$(System.DefaultWorkingDirectory)
echo $HELM_HOME
ls -l $(System.DefaultWorkingDirectory)

Output

What catches my eye is the undefined directory in the $HELM_HOME, it also appears in the original error message : undefined/repository/cache/undefined/repository/cache/rook-master-index.yaml: no such file or directory. Are you sure it's not coming from the extension's transpiled .ts code?

[debben]

Worth noting too that Helm home directory can also be configured with the "--home" global flag.

[mmisztal1980]

Let me try that

[mmisztal1980]

@debben providing HELM_HOME via the --home flag seems to have solved the issue.

Thanks!
