     Image scan	option	Automatic scanning of image vulnerabilities generated in the repository and setting scan exclusion policies You can set the default scan policy applied when an image is created in the repository If you set automatic scanning to enabled, the image’s vulnerabilities are automatically checked when the image is pushed.
