v0.11.0: unsupported manifest media type and no default available: application/vnd.oci.image.manifest.v1+json

[nvhoc]

Environment:

• GitHub Action
• Job wrapped by container "node:16.18.0-alpine"
• Docker version: 20.10.20
• moby/buildkit:v0.11.0
• Run Docker in Docker to push a new version

Issue:

When pushing new tag, it creates 3 tags to ECR:

When I try to inspect its manifest

docker manifest inspect ${AWS_ACCOUNT_ID}.dkr.ecr.ap-southeast-2.amazonaws.com/server:${TAG}

I got a message:

unsupported manifest media type and no default available: application/vnd.oci.image.manifest.v1+json

My temporary solution:

• Move back moby/buildkit:v.10.5, the job now is working normal

This looks to be the same issue as docker/buildx#1509 👀

It looks like the docker manifest doesn't support OCI indexes - which ideally, it should.

Here's a couple things you might try in the meantime.

• Use docker buildx imagetools inspect instead of docker manifest inspect --raw - it should work similarly, and supports all the different media types in the registry.
• Set oci-mediatypes=false in your --output flag (to use the docker distribution manifest list instead of an OCI index)
• Set --provenance=false to not generate the provenance (which is what causes the multi-platform index to be generated, even for a single platform).
