Export images to an arbitrary repository according to a template specified by the --tag option (build if needed).
The tag may contain the following shortcuts:
image,image_slugorimage_safe_slugto use the image name (necessary if there is more than one image in the werf config);image_content_based_tagto use a content-based tag. All meta-information related to werf is removed from the exported images, and then images are completely under the user’s responsibility.
