Fill out description fields in registry?

[vielmetti]

The Docker registry has some descriptive fields in it that allow the developer to (somehow) give some text description to the image.

If you upload to Docker hub with this tool, those fields are blank, cf. https://hub.docker.com/r/vielmetti/multiarch-gitea/

It would be a welcome extension to manifest-tool to support updating those fields. (Or, if that's out of scope for this tool because of lack of registry standardization, a pointer to a tool that would do that task welcomed.) I see docker-archive/docker-registry#561 as one possible non-API answer to this task.

One of the issues here is that if we are talking about author/comment information, these are per-image and specific to an image config. The manifest list object type does not duplicate these fields, so there is nowhere in the manifest list "object" to place things like "author" or "comment". They will still exist in the target images (which must already exist somewhere on DockerHub or a private registry), but the manifest list has no way to represent that, and DockerHub (or the Docker Store) currently has no UI to reveal this information for manifest list types stored in the registry.

As a side node, I believe Docker Store is going to be enhanced to understand manifest list entries and show more detail (like an icon for each architecture/platform supported), but I don't have visibility into timing or plans there.

Let me know if I've misunderstood your request!

I think https://github.com/docker/hub-tool is going to be our best hope for this one. 😅

Edit: specifically, that'd be docker/hub-tool#172
