Description

I've encountered limitations with the azurerm_data_protection_backup_instance_kubernetes_cluster resource that impact usability for scenarios requiring namespace-wide Kubernetes backups:

1. Missing "All Namespaces" Option: The backup_datasource_parameters argument block lacks an all_namespaces parameter that would automatically include all namespaces for backup, requiring users to manually specify each namespace.

2. "included_namespaces" Parameter Limitation: The included_namespaces parameter within the backup_datasource_parameters does not accept universal selectors like * or all, which would typically be used to denote the inclusion of all namespaces.

I believe introducing an all_namespaces parameter or allowing included_namespaces to accept values like * or all would be a much needed functionality.

Potential Terraform Configuration

resource "azurerm_data_protection_backup_instance_kubernetes_cluster" "example" {
  name                         = "example"
  location                     = azurerm_resource_group.example.location
  vault_id                     = azurerm_data_protection_backup_vault.example.id
  kubernetes_cluster_id        = azurerm_kubernetes_cluster.example.id
  snapshot_resource_group_name = azurerm_resource_group.snap.name
  backup_policy_id             = azurerm_data_protection_backup_policy_kubernetes_cluster.example.id

  backup_datasource_parameters {
    excluded_namespaces              = ["test-excluded-namespaces"]
    excluded_resource_types          = ["exvolumesnapshotcontents.snapshot.storage.k8s.io"]
    cluster_scoped_resources_enabled = true
    included_namespaces              = ["all"]
    all_namespaces                   = true
    included_resource_types          = ["involumesnapshotcontents.snapshot.storage.k8s.io"]
    label_selectors                  = ["kubernetes.io/metadata.name:test"]
    volume_snapshot_enabled          = true
  }
}
