+# huaweicloud\_iec\_images
+
+Use this data source to get the available of HuaweiCloud IEC images.
+
+## Example Usage
+
+```hcl
+data "huaweicloud_iec_images" "iec_image" {
+  os_type = "Linux"
+}
+```
+
+## Argument Reference
+
+The following arguments are supported:
+* `region` - (Optional, String) The region in which to obtain the images. 
+    If omitted, the provider-level region will be used.
+
+* `name` -  (Optional, String) Specifies the image Name, which can be queried 
+    with a regular expression.
+
+* `os_type` - (Optional, String) Specifies the os type of the iec image. 
+    "Linux", "Windows" and "Other" are supported.
+
+## Attributes Reference
+
+In addition to all arguments above, the following attributes are exported:
+
+* `images` - An array of one or more image.
+    The images object structure is documented below.
+
+The `images` block supports:
+
+* `id` - The id of the iec images.
+* `name` - The name of the iec images.
+* `status` - The status of the iec images.
+* `os_type` - The os_type of the iec images.
