bug: https://hub.docker.com/r/arm32v6/alpine/

[userdocs]

Since this update i am seeing this error in github actions

Run docker run --name multiarch -it -d -w /root -e CXXFLAGS="--static -static -std=c++17" -e CPPFLAGS="--static -static" -e LDFLAGS="--static -static" --platform linux/arm/v6 -v /home/runner/work/iperf3-static/iperf3-static:/root arm32v6/alpine:edge

It would seem this is incorrect linux/arm/v7 if i am still using arm32v6/alpine:edge as the container?

This is an unfortunate intersection of a few factors (Docker 20.10+, containerd's platform normalization, docker build's default behavior), but I've filed docker-library/bashbrew#29 to track this issue in bashbrew because that's probably going to be the most appropriate place to fix the specific case of the metadata on these Alpine images.

Ok, thanks for the update. My workflow just started failing and I did not fully understand why so this is helpful info to know. I'll keep an eye on it and hopefully it is resolved .

I still have this with the latest released image (16 hours ago) https://hub.docker.com/r/arm32v6/alpine/

https://github.com/userdocs/iperf3-static/runs/3449942070?check_suite_focus=true

Any idea when the fix will filter through?

I'm not sure why Docker Hub doesn't show it, but the pushed image definitely has variant: "v6" set: 😕

I see this also when using docker rootless on a server

docker run --rm arm32v6/alpine:edge sh -c 'cat /etc/*release'

Looking here at the hash i see this is maybe a month old?

Yeah, somehow arm32v6/alpine:edge didn't get updated properly and had variant: "v7" of all things -- it should be updated now though (I've just forced it to rebuild).

[userdocs]

Yes that was it. It is working now https://github.com/userdocs/iperf3-static/runs/3465215662?check_suite_focus=true

Thanks for the fix.
