[chdalski]

Hi there,

azurerm doesn't fetch the tags from an eventhub_namespace as expected.

Please see below for details.

Terraform (and AzureRM Provider) Version

Verifying Terraform installation...
/opt/hostedtoolcache/terraform/0.15.4/x64/terraform version
Terraform v0.15.4
on linux_amd64

Initializing provider plugins...

• Finding latest version of hashicorp/azurerm...
• Installing hashicorp/azurerm v2.61.0...
• Installed hashicorp/azurerm v2.61.0 (signed by HashiCorp)

Affected Resource(s)

• azurerm_eventhub_namespace

Terraform Configuration Files

resource "azurerm_eventhub_namespace" "event_hub_namespace" {
  name                     = "example"
  resource_group_name      = var.resource_group_name
  location                 = var.location
  sku                      = "Standard"
  capacity                 = 1
  auto_inflate_enabled     = true
  maximum_throughput_units = 4

  tags = {
     Environment       = "test"
     ResourceGroupName = "TEST-RG"
  }
}

Expected Behaviour

"terraform apply" applies the tags correctly

after applying the next "terraform plan" should show no changes

Actual Behaviour

"terraform apply" applies the tags correctly

after applying the next "terraform plan shows:

  # azurerm_eventhub_namespace.event_hub_namespace will be updated in-place
  ~ resource "azurerm_eventhub_namespace" "example" {
        id                                  = "/subscriptions/XYZ/resourceGroups/TEST-RG/providers/Microsoft.EventHub/namespaces/example"
        name                                = "example"
      ~ tags                                = {
          ~ "Environment"       = "TEST-RG" -> "test"
            # (1 unchanged element hidden)
        }
        # (12 unchanged attributes hidden)
    }

Somehow the tags are incorrectly read by azurerm from the eventhub_namespace.
The tags are correctly displayed in Azure Portal.

The problem isn't present in version 2.60.

i thought maybe this was our blueprint doing something bad..but guess it's terraform. No plan comes back as clean now :(

I'm having the same issue. I tried with terraform 0.14.0 and 0.14.11, azurerm provider 2.22.0 and 2.62.0. I tried a couple of combination without success.

Looks like it takes one of the tags value randomly, and applies its value to all other tags.

Fixed via #12062

This has been released in version 2.63.0 of the provider. Please see the Terraform documentation on provider versioning or reach out if you need any assistance upgrading. As an example:

provider "azurerm" {
    version = "~> 2.63.0"
}
# ... other configuration ...
