creating resource group client: %w

Error message

creating resource group client: %w

What it means

Wraps failure of resources.NewResourceGroupsClient, the constructor for the ARM resource groups client. As with the other Azure client constructors, failure means the SDK could not build a client pipeline for the given subscription ID and credential/options.

Solutions

  1. Pass a valid, non-empty subscription ID (check AZURE_SUBSCRIPTION_ID / cluster spec)
  2. Confirm cred (DefaultAzureCredential) is non-nil and was built successfully
  3. After upgrading azure-sdk-for-go modules, update the constructor call to the new API
  4. Set AZURE_TENANT_ID/CLIENT_ID/CLIENT_SECRET explicitly if environment auth is expected
Defensive patterns

Strategy: validation

Validate before calling

if strings.TrimSpace(subscriptionID) == "" {
  return errors.New("azure: resource groups client requires a non-empty subscription ID")
}
if cred == nil {
  return errors.New("azure: credential must be constructed before creating clients")
}

Type guard

func isValidSubscriptionID(id string) bool {
  re := regexp.MustCompile(`^[0-9a-fA-F-]{36}$`)
  return re.MatchString(id)
}

Try / catch

rgc, err := newResourceGroupsClientImpl(subID, cred)
if err != nil {
  return nil, fmt.Errorf("cannot build azure cloud (check AZURE_SUBSCRIPTION_ID and credentials): %w", err)
}

Prevention

When it happens

Trigger: newResourceGroupsClientImpl(subscriptionID, cred) called (from newAzureCloud) with an empty subscription ID or invalid credential/options.

Common situations: Missing or empty subscription ID in kOps Azure cloud configuration; constructing the cloud before credentials are resolved; SDK version upgrade changing the constructor signature/behavior.
