Shouldn't use resourcegroup().name in dns labels or storage account names

This always leads to validation errors - dns names and storage account names cannot have uppercase letters or dashes '-'.

See Azure/azure-quickstart-templates Issue #2990, and #12.

Per Best Practices guidelines for Resources: domainNameLabels should use uniquestring(resourceGroup().id) instead in all cases.

Keith suggested that a quick way to solve this would be to convert the RG name to all lower case and remove non-alphanumeric characters using the toLower() and -replace. Something like the following:

$string = $string.ToLower()
$string = -replace "[^a-z0-9]", ''
