cni-plugin container for ARM64 appears to have the AMD64 binaries

[hagak]

I am trying to deploy multus to an ARM64 env and using your cni-plugins image the init container runs successfully but the /opt/cni/bin binaries it deploys appear to be for amd64.

I then created a pod with the ghcr.io/angelnu/cni-plugins:1.5.0 image but change the entry point to be a continous loop so I could inspect the image. I tried running the /plugins/macvlan within the container and it return the "exec format error". I then from inside the container did a wget https://github.com/containernetworking/plugins/releases/download/v1.5.0/cni-plugins-linux-arm64-v1.5.0.tgz and extracted the binaries to /plugins and performed the test again and was presented with the version info as expected.

Thanks for reporting. The github action at https://github.com/angelnu/containers/blob/main/.github/workflows/action-image-build.yaml seems to only be building amd64...

Will need to find out why as the cni-plugins also include arm64 as target platform

[hagak]

So the image that is built is an arm64 image just the binaries for cni-plugins are not. I suspect whatever is defining TargetArch is the issue. Targetplatform seems correct. Sorry responding on my phone so going off memory here.

[angelnu]

The location is here. TARGETARCH should be set automatically by buildah - https://github.com/containers/buildah/issues/1368

So we need to find why it is not working if platform is right according to your comment. A focker inspect of the image would help to see the link that was downloaded.

We would need the commands used to build the layers to see how the variables in tje download url were expanded. See https://github.com/containers/buildah/issues/1368#issuecomment-818385728

[hagak]

Not sure how i can help with that, I am not familiar with the build process you have.
