+# huaweicloud_gaussdb_opengauss_pt_applicable_instances
+
+Use this data source to get the GaussDB OpenGauss instances that a parameter template can be applied to.
+
+## Example Usage
+
+```hcl
+variable "config_id"  {}
+
+data "huaweicloud_gaussdb_opengauss_pt_applicable_instances" "test" {
+  config_id = var.config_id
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+
+* `region` - (Optional, String) Specifies the region in which to query the resource.
+  If omitted, the provider-level region will be used.
+
+* `config_id` - (Required, String) Specifies the parameter template ID.
+
+## Attribute Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `id` - The data source ID.
+
+* `instances` - Indicates the list of instances that the parameter template can be applied to.
+
+  The [instances](#instances_struct) structure is documented below.
+
+<a name="instances_struct"></a>
+The `instances` block supports:
+
+* `instance_id` - Indicates the instance ID.
+
+* `instance_name` - Indicates the instance name.
