supposed to be generated when the disk_format is defined.

+## How to test 
+The steps and overview about a feature described in [disk-format](../../../../config/samples/disk_formats/) document  
+We assume one GlanceAPIs exist, disk format is enabled with disk formats
+'raw, iso' and image is created with same disk format.
+
+### Step 1:  Create image
+In this step we create images with 'raw' and 'iso' disk formats
+```bash
+    $glance --verbose image-create \
+        --disk-format "$1" \
+        --container-format bare \
+        --name "${IMAGE_NAME}"
+```
+
+## EXAMPLE
+
+The example assumes a glanceAPI is deployed using [single layout](https://github.com/openstack-k8s-operators/glance-operator/tree/main/config/samples/layout/single).
+
+Copy the [`create-image.sh`](create-image.sh) script to the target container
+where the `glance` cli is available.
+For example:
+
+```bash
+$oc cp create-image.sh openstackclient:/scripts
+```
+
+Create image with 'raw' disk format
+
+```bash
+sh-5.1# bash create-image.sh raw
+glance --os-auth-url https://keystone-public-openstack.apps-crc.testing --os-project-name admin --os-username admin --os-password 12345678 --os-user-domain-
+name default --os-project-domain-name default --verbose image-create --disk-format raw --container-format bare --name myimage-disk_format-test

+# How to test 
+
+The goal of this test is to verify if user can set disk format for image that should be created
+
+## Kuttl test steps
+The steps and overview about a feature described in [disk-format](../../../../config/samples/disk_formats/) document
+We assume one GlanceAPIs exist, disk format is enabled with disk formats
+'raw, iso' and image is created with same disk format.
+
+### Step 1:  Create image
+In this step we create images with disk formats  'raw,iso'
+```bash
+    $glance --verbose image-create \
+        --disk-format "$1" \
+        --container-format bare \
+        --name "${IMAGE_NAME}"
+```
+
+## Conclusion
+The steps described above are automated by this
+[script](../../../../config/samples/glance_disk_formats/create-image.sh)
+that is executed by the kuttl test once the environment is deployed and the
+`openstackclient` is ready.
