Generic Registries

crane

crane is a tool that allows you to interact with OCI repositories.

See recipes.md for additional recipes.

Getting images using the Catalog API

crane catalog <registry>

This command will query a registry for available repositories using the OCI Catalog API. NOTE: not all registries support this endpoint.

Registries we know this works with:

• Google Container Registry
• Google Artifact Registry
• Harbor
• Microsoft Container Registry

Examples

• crane catalog gcr.io

Listing tags

crane ls <repo> --omit-digest-tags --full-ref

• --omit-digest-tags suppresses .sbom/.att tags.
• --full-ref prints the full image reference.
