Apply annotations with ORAS¶

The JSON written by cwl2oci follows the ORAS annotation-file format. After generating annotations.json, pass it to an ORAS command that creates a manifest.

For example, to push workflow.cwl as an artifact:

oras push \
  --annotation-file annotations.json \
  --artifact-type application/cwl \
  registry.example.com/workflows/hello:1.0.0 \
  workflow.cwl:application/cwl

ORAS treats the $manifest entry as annotations for the new manifest. Verify the result:

oras manifest fetch \
  registry.example.com/workflows/hello:1.0.0 \
  --pretty

The fetched manifest contains the generated values in its annotations field. Authentication, registry naming, artifact media types, and publication policy are outside cwl2oci; adapt those values to your registry.

See the ORAS guide to manifest annotation files for other targets such as $config and individual layer filenames.
