Recommended Helm Configuration for stackablectl?

[msen7437]

I came across this problem in using stackablectl:

> stackablectl operator list
An unrecoverable error occured: failed to execute operator (sub)command

Caused by these errors (recent errors listed first):
 1: Helm error
 2: failed to retrieve remote content
 3: error sending request for url (https://repo.stackable.tech/repository/helm-stable/index.yaml)
 4: client error (Connect)
 5: invalid peer certificate: UnknownIssuer

I updated the certificates and tried to add the repository using --insecure-skip-tls-verify. The endpoint of the index.yaml is reachable via curl. Installing Operators works fine, but listing Operators, demos or stacks and installing demos and stacks does not work.
It appears to be an issue with helm.

When i run that command in debug mode i noticed this entry right before the error message:

  DEBUG  ALPN protocol is None

    in run with self: Cli { log_level: Some(Level(Debug)), no_cache: false, offline: false, files: CommonFileArgs { demo_files: [], stack_files: [], release_files: [] }, repos: CommonRepoArgs { helm_repo_stable: "https://repo.stackable.tech/repository/helm-stable/", helm_repo_test: "https://repo.stackable.tech/repository/helm-test/", helm_repo_dev: "https://repo.stackable.tech/repository/helm-dev/" }, subcommand: Operator(OperatorArgs { subcommand: List(OperatorListArgs { output_type: Table }) }) }

On a server where stackablectl operator list is working it says ALPN protocol is Some(b"http/1.1").

I cannot reproduce or fix this issue.
I do not think, that this Issue is a bug, thats why I added it under "question".

There is no need to manually add the Helm repositories before using stackablectl. It does this automatically by itself.

The error you encountered seems to be related to a server hiccup. Are you using any tool which might intercept traffic (eg. a proxy)? I failed to reproduce this (and you seem to have failed too). Listing and installing components (demos, stacks, operators) worked fine for me.

So for now, I'm gonna assume this is a non-issue and won't need any fix.
