Description W. Trevor King 2020-10-22 17:26:55 UTC

Description of problem:

For a public image with a application/vnd.oci.image.manifest.v1+json manifest, 'oc image info $PULLSPEC' and other oc tooling claim 'does not exist' instead of successfully accessing the manifest.

Version-Release number of selected component (if applicable):

$ oc version --client
Client Version: 4.5.11

How reproducible:

Every time.

Steps to Reproduce:

$ oc --v=8 image info docker.io/sjenning/olm:dev-5

Actual results:

I dunno why oc does not appear to include application/vnd.oci.image.manifest.v1+json when making requests of the manifests/{tag} endpoint.

Comment 1 Seth Jennings 2020-10-22 17:40:41 UTC

I deployed my own registry using docker's registry:2 image, pushed the image build with podman to the registry and then `oc image info`ed it.  It failed.  The log from the registry side is:

level=error msg="response completed with error" err.code="manifest unknown" err.message="OCI manifest found, but accept header does not support OCI manifests"

Comment 3 Sally 2020-11-12 17:40:56 UTC

Actively working on this, adding UpcomingSprint.

Comment 4 Michal Fojtik 2020-11-21 19:12:05 UTC

This bug hasn't had any activity in the last 30 days. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. As such, we're marking this bug as "LifecycleStale" and decreasing the severity/priority. If you have further information on the current state of the bug, please update it, otherwise this bug can be closed in about 7 days. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. Additionally, you can add LifecycleFrozen into Keywords if you think this bug should never be marked as stale. Please consult with bug assignee before you do that.

Comment 5 Sally 2020-12-05 00:25:09 UTC

There are many schema 1 images on quay that do work fine with `oc image info`, for example here are a few:

quay.io/openshift/origin-cluster-version-operator:4.6.0
quay.io/openshift/origin-console:4.6.0
quay.io/openshift/origin-console-tests:4.6.0
quay.io/openshift/origin-docker-builder:4.6.0

With the 'Media Type:  application/vnd.docker.distribution.manifest.v1+prettyjws'  

Then, I can do this (also running w/ the local podman registry image) :

$ oc image mirror quay.io/openshift/origin-docker-builder:4.6.0=localhost:5000/docker-builder:4.6.0

and then this works fine

$ oc image info localhost:5000/docker-builder:4.6.0

Does this work for you? 

`oc` does handle schema version 1 images, it will upconvert them to v2 so when you mirror a v1 you'll end up w/ a new digest and you'll see a warning:
"warning: Digests are not preserved with schema version 1 images. Support for schema version 1 images will be removed in a future release" but I don't have any trouble accessing them with `oc image info`.

That's quay.io saying "sure, I can serve that to you in application/vnd.docker.distribution.manifest.v1+prettyjws, which is one of the types you can Accept".  But if we were talking to a registry about a manifest that could only be served as application/vnd.oci.image.manifest.v1+json , oc would be out of luck, right?

The LifecycleStale keyword was removed because the bug got commented on recently.

Comment 9 Sally 2021-01-12 14:15:26 UTC

I'm getting back to this bug now, was set aside due to other bugs with higher priority. In the least, oc should provide a more accurate error message. I'll also look into why oc can't accept the OCI manifest. For example, when I try to mirror that image I see this (a bit better) error message:

$ oc image mirror docker.io/sjenning/olm:dev-5=localhost:5000/olm:dev

error: unable to retrieve source image docker.io/sjenning/olm by tag dev-5: manifest unknown: OCI manifest found, but accept header does not support OCI manifests
error: an error occurred during planning
