Azure Container Apps restart serveral times even if my batch is terminated - azure-container-instances

Question

I am implementing a batch in Azure Container Apps.
When a message comes from a queue in service bus then my batch is run.
For this, I added a scale rule to automatic scale when a message comes from the queue.
It works well, when there is a message it is scaled out from 0 to 1 replica. But when my batch is terminated, the replica restarts the container several times until it is scaled in to 0.
Here is my terraform script to create the container apps :
resource "azapi_resource" "container_app" {
name = var.container_app_name
location = "northeurope"
parent_id = data.azurerm_resource_group.resource_group.id
identity {
type = "UserAssigned"
identity_ids = [data.azurerm_user_assigned_identity.aca_identity.id]
}
type = "Microsoft.App/containerApps#2022-03-01"
body = jsonencode({
properties: {
managedEnvironmentId = data.azapi_resource.container_environment.id
configuration = {
secrets = [
{
name = "regitry-password"
value = data.azurerm_container_registry.acr.admin_password
},
{
name = "service-bus-connection-string"
value = data.azurerm_servicebus_namespace.servicebus.default_primary_connection_string
}
]
ingress = null
registries = [
{
server = data.azurerm_container_registry.acr.login_server
username = data.azurerm_container_registry.acr.admin_username,
passwordSecretRef = "regitry-password"
}]
}
template = {
containers = [{
image = "${data.azurerm_container_registry.acr.login_server}/${var.container_repository}:${var.container_image_tag}"
name = "dbt-instance"
resources = {
cpu = var.container_cpu
memory = var.container_memory
}
env = [
{
name = "APP_CONFIG_NAME"
value = var.app_configuration_name
},
{
name = "AZURE_CLIENT_ID"
value = data.azurerm_user_assigned_identity.aca_identity.client_id
}
]
}]
scale = {
minReplicas = 0
maxReplicas = 5
rules = [{
name = "queue-based-autoscaling"
custom = {
type = "azure-servicebus"
metadata = {
queueName = var.service_bus_queue_name
messageCount = "1"
}
auth = [{
secretRef = "service-bus-connection-string"
triggerParameter = "connection"
}]
}
}]
}
}
}
})
How to run my container only one time ?
I managed to do it with Azure Container Instance with the property "restartPolicy=Never"
