Introduction

Event Grid module can deploy these resources:

  • azurerm_eventgrid_system_topic (optional)
  • azurerm_monitor_diagnostic_setting (optional)

Example variables structure is located in variables.md.

Example use case is located in test-case/locals.tf.

You can also see changelog.

Terraform documentation:

https://registry.terraform.io/providers/hashicorp/azurerm/4.14.0/docs/resources/eventgrid_system_topic

https://registry.terraform.io/providers/hashicorp/azurerm/4.14.0/docs/resources/monitor_diagnostic_setting

 

WARNING: AzureRM provider had been updated to a new major version. Many breaking changes were implemented. See the providers guide for more information.

Terraform Import

There are a few things you need to do to import resources into .tfstate. In the example below there are resources which can be imported within the module. You may need to modify these commands to the OS on which they will be running (Refer to the documentation for additional details).

Event Grid System Topic

terraform import '<path-to-module>.azurerm_eventgrid_system_topic.eventgrid_system_topic["<eventgrid-system-topic-name>"] /subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.EventGrid/systemTopics/<eventgrid-system-topic-name>'

Diagnostic Setting

  • terraform import '<path-to-module>.azurerm_monitor_diagnostic_setting.diagnostic_setting["<eventgrid-system-topic-name>_<diag-name>"]' '/subscriptions/<subscription-id>/resourceGroups/<resource-group-name>/providers/Microsoft.EventGrid/systemTopics/<eventgrid-system-topic-name>|<diag-name>'

NOTE: <path-to-module> is terraform logical path from root. e.g. module.event_grid

 

Outputs

Structure

Output Name Value Comment
outputs system_topic Event Grid System Topic outputs
 name
 id
 principal_id principal_id (object_id) of system assigned identity

Example usage of outputs

In the example below, outputted id of the deployed Event Grid module is used as a value for the scope variable in Role Assignment resource.

module "eg" {
    source = "[email protected]:seyfor-csc/mit.event-grid.git?ref=v1.0.0"
    config = {
    system_topic = [
      {
        name                   = "seyterraformne01"
        resource_group_name    = "SEY-TERRAFORM-NE-RG01"
        location               = "northeurope"
        source_arm_resource_id = azurerm_storage_account.sa.id
        topic_type             = "Microsoft.Storage.StorageAccounts"
      }
    ]
  }
}

data "azurerm_client_config" "azurerm_client_config" {
}

resource "azurerm_role_assignment" "role_assignment" {
    scope                = module.eg.outputs.system_topic.seyterraformne001.id # This is how to use output values
    role_definition_name = "Contributor"
    principal_id         = data.azurerm_client_config.azurerm_client_config.object_id
}
