Terraform (and AzureRM Provider) Version

• Terraform 0.14.4
• AzureRM 2.48

Affected Resource(s)

• azurerm_storage_container

Terraform Configuration Files

resource "azurerm_storage_container" "container" {
  name                  = module.container_name.name
  storage_account_name  = var.storage_account_name
  container_access_type = var.container_access_type
  metadata              = var.metadata
}

Where metadata looks something like this

metadata = {
  meta        = "data"
  noUpperCase = "none"
}

Debug Output

Debug output may contain sensitive stuff to which I don't think I can share publicly.

Expected Behaviour

It should either accept that upper case characters is a valid name. Or, if this is a known Azure limitation, it should be documented as such that only lower case characters plus underscores are allowed in the container metadata.

Actual Behaviour

Error: MetaData must start with letters or an underscores. Got "noUpperCase".

  on ../../_modules/container/main.tf line 9, in resource "azurerm_storage_container" "container":
   9: resource "azurerm_storage_container" "container" {

Steps to Reproduce

1. terraform apply

          ~ resource "azurerm_storage_container" "test" {
                id                      = "https://acctestacc2vr04.blob.core.windows.net/vhds"
              ~ metadata                = {
                  + "upperCase" = "something"
                  - "uppercase" = "something" -> null
                    # (2 unchanged elements hidden)
                }
                name                    = "vhds"
                # (5 unchanged attributes hidden)
            }

Seems to be Azure API limitation, will adjust error message and docs.
