Doesn't zot allow application/vnd.oci.artifact.manifest.v1+json as media type?

[nevotheless]

Howdy, i'm currently discoverying some possibilities to develop a tool which helps our development workflow and was coming from the oras project, which has

oras push --image-spec v1.1-artifact localhost:5000/hello:v1 hi.txt

within their docs to upload an artifact as an actual oci artifact and not as an oci image spec artifact (as far as i understand). Is this just not supported yet from a zot registry, or am i missing something?

Nevermind my question, i just saw that zot is a little dated and the prefered way for local verification is the registry https://github.com/distribution/distribution

Hi @nevotheless,

We have examples for oras usage at: https://github.com/project-zot/zot/blob/main/test/blackbox/pushpull.bats#L103
We are supporting the latest OCI image spec with the current definitions of artifacts.

Note the --image-spec v1.1-artifact was an experiment which didn't make it in the next iteration of the OCI spec, it was removed in opencontainers/image-spec#999.
We removed support for that experiment in the latest zot.
You should take note of that even if you decide to use another registry instead of zot.

You should switch to --image-spec v1.1-image see the examples in the tests I linked above.

Short version is application/vnd.oci.artifact.manifest.v1+json doesn't exist anymore in the OCI spec.

Thanks for your answer. Yeah i searched through some github issues yesterday and found that out as well. I thought that application/vnd.oci.artifact.manifest.v1+json relates to the distribution spec. I'm new to this whole world and still don't quite understand which parts belong to what other part.
