+# huaweicloud_cdn_domain_template_apply
+
+Manages a CDN domain template apply resource within HuaweiCloud.
+
+-> This resource is a one-time action resource for applying CDN domain template to domains. Deleting this resource will
+   not clear the corresponding request record, but will only remove the resource information from the tfstate file.
+
+## Example Usage
+
+```hcl
+variable "template_id" {}
+variable "apply_domain_names" {
+  type = list(string)
+}
+
+resource "huaweicloud_cdn_domain_template_apply" "test" {
+  template_id = var.template_id
+  resources   = join(",", var.apply_domain_names)
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `template_id` - (Required, String) Specifies the ID of the domain template to apply.
+
+* `resources` - (Required, String) Specifies the list of domain names to apply the template.  
+  Multiple domain names are separated by commas (,).  
+  A maximum of 50 domains can be applied in a single operation.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The resource ID.
