Description

Description

I used to build multiarch containers by compiling for arm processor directly on my M1/M2 MBP and using an intel nuc for linux/amd64 versions.

Then I create the multiarch image by running docker manifest commands.

I pilot the build process on the intel nuc from my MBP by using a specific docker context.

I discovered today that my docker version now flags the intel nuc image build from my MBP with the specific nuc context as linux/arm64/v8.

If I build the image directly on the nuc by sshing, the architecture/os/variant are correct.

Note this used to work correctly for years, this break recently but I can't tell when.

Reproduce

Dockerfile

FROM hello-world
docker --context nuc image build --tag build_context --load .
docker --context nuc image inspect build_context | grep -e "Archi"
        "Architecture": "arm64",
ssh nuc
docker image build --tag build_local --load .
docker image inspect build_local | grep -e "Archi"
       "Architecture": "amd64",
Expected behavior

The image should be tagged correctly "amd64"
