Description

It would be usefull to be able to configure the pollingInterval and cooldownPeriod for the KEDA scalers of Azure Container Apps, like it is already possible to do through the ARM template.
Currently, the azurerm provider does not expose those properties.

New or Affected Resource(s)/Data Source(s)

azurerm_container_app

Potential Terraform Configuration

This could look like this:

resource "azurerm_container_app" "example" {
  name                         = "example-app"
  container_app_environment_id = azurerm_container_app_environment.example.id
  resource_group_name          = azurerm_resource_group.example.name
  revision_mode                = "Single"

  template {
    container {
      name   = "examplecontainerapp"
      image  = "mcr.microsoft.com/k8se/quickstart:latest"
      cpu    = 0.25
      memory = "0.5Gi"
    }
    custom_scale_rule {
      name             = "cpuscalingrule"
      custom_rule_type = "cpu"
      metadata = {
        type  = "Utilization"
        value = 70
      }
    }
    max_replicas = 10
    min_replicas = 0
    polling_interval = 30
    cooldown_period = 300
  }
}

@LandryDubus could you provide the ARM template that supports this feature? I checked a few and didn't see one.

Also looking for this functionality but the API is still in preview.

The link to the template is in my original post.

@LandryDubus thanks! Not sure how I missed that last time. The link took me somewhere else?

Anyway, @jsheetzmt is correct, this is part of the preview API and won't be added to the azurerm provider until a stable API is published that supports it. In the meantime, you can use the azapi provider.
