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_slug or image_safe_slug to use the image name (necessary if there is more than one image in the werf config);
  • image_content_based_tag to 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.


werf export [IMAGE_NAME...] [options]


  # Export images to Docker Hub and GitHub container registry
  $ werf export \
      --tag index.docker.io/company/project:%image%-latest \

  # Export images with extra labels
  $ werf export \
      --tag registry.werf.io/company/project/%image%:latest \
