+  Manage a CAE domain name resource within HuaweiCloud.
+---
+
+# huaweicloud_cae_domain
+
+Manage a CAE domain name resource within HuaweiCloud.
+
+## Example Usage
+
+```hcl
+variable "environment_id" {}
+variable "domain_name" {}
+
+resource "huaweicloud_cae_domain" "test" {
+  environment_id = var.environment_id
+  name           = var.domain_name
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String, ForceNew) Specifies the region in which to create the resource.
+  If omitted, the provider-level region will be used.
+  Changing this creates a new resource.
+
+* `environment_id` - (Required, String, ForceNew) Specifies the ID of the CAE environment.
+  Changing this creates a new resource.
+
+* `name` - (Required, String, ForceNew) Specifies the domain name to be associated with the CAE environment.
+  Changing this creates a new resource.  
+  The maximum length of the domain name is `254` characters.  
+  The domain name consists of multiple strings separated by dots (.), and the maximum length of a single string is `63` characters.
+  Only letters, digits, and hyphens (-) allowed, and must start with a letter or a digit.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The resource ID, in UUID format.
+
+* `created_at` - The time when the domain name is associated, in RFC3339 format.
+
+## Import
+
+The resource can be imported using `environment_id` and `name`, separated by a slash (/), e.g.
+
+```bash
+$ terraform import huaweicloud_cae_domain.test <environment_id>/<name>
+```
