OCI images with annotations?

[srenatus]

Hello!

I'm trying to consume a ko-built OCI image from another tool, and that one depends on having a tag, i.e. org.opencontainers.image.ref.name in the annotations of the OCI archive.

Having dug around a bit, that seems like it's not possible right now? I would have hoped that the --tags flag together with --oci-layout-path would do the trick, but it doesn't seem to 🤔

(See https://github.com/opencontainers/image-spec/blob/main/image-layout.md#indexjson-file)

I believe this already works except for publishing manifest lists. If your base image is an OCI image index and you're pushing an index, it will contain annotations. If your base image is a manifest list (per docker media types), it will publish a manifest list without annotations.

Oh I misread, I was thinking about org.opencontainers.image.base.name.

Do you expect org.opencontainers.image.ref.name to contain just a tag? Or a full image ref?

I'm not sure, I'll have to check... Just had it fail without anything set so far... I'll get back to you

FWIW adding the annotation, and using a recent-enough ko version (it seems distroless.dev/ko didn't have #776) made it work out fine: https://github.com/srenatus/opa-x/blob/main/ko.bass. There, I'm just adding a "latest" ref name, because it's enough to make it work.
