The final QCOW2 image can be used:

1. In manifests as KRM-function to get information about all Vars that were used to build that image, including the link to image-builder. See qcow-bundle metainformation section.

# QCOW bundle metainformation
QCOW bundle contains metainformation about Ansible var values that were used when the image was built.
This information can be taken and used, because QCOW bundle is implemented as a KRM-function. See [the example](/image-builder/krm-function/example/).
NOTE: replace `image:` URL with the one you want to get information about. Execute `kustomize build --enable-alpha-plugins <folder>` and it will output something like:
```
apiVersion: airshipit.org/v1alpha1
kind: VariableCatalogue
metadata:
name: profile_multistrap
inventory_hostname_short: localhost
k8s_version: 1.18.6-00
kdump_tools:
crashkernel: 768M
...
```
This VariableCatalogue contains all vars that were set when image-builder Docker images was built. To get that `configPath: /profiles/profile_multistrap.json` is used.
This file is created during image-builder build process. Image-builder allows to override some parameters on QCOW-bundle generation. These values are also available
and can be seen with `configPath: /profiles/profile_qcow_<qcow-image-settings-folder-name>.json`, e.g. `configPath: /profiles/profile_control-plane.json` or `configPath: /profiles/profile_data-plane.json`. That profile also contains information about the URL to image-builder that was used to product qcow-bundle: see field `image_builder_image`.
This information can be used to build manifests that don't have duplication.
E.g. k8s version rather than to be set ALONG with url of qcow-bundle, can be taken from qcow-bundle. That means that it's possible only to put info about qcow-bundle and information about k8s that it contains will be available. This may also reduce the size of Catalogues in general.
The implementation is based on the following 2 playbook calls:
```shell
ansible-playbook -i assets/playbooks/inventory.yaml assets/playbooks/profile_generation.yaml
ansible-playbook -i assets/playbooks/inventory.yaml assets/playbooks/profile_resolution.yaml
```
As a result the file `assets/playbooks/config.json` will appear with all configurable image-builder variables resolved.
