linux/arm/v8 platform not supported

[SinaYa]

I'm trying to run the docker image using this command:
docker run --name --platform linux/arm/v8 vpnconf -e SPW=<password> -e HPW=<password> siomiz/softethervpn echo

and I get this error:
docker: Error response from daemon: pull access denied for linux/arm/v8, repository does not exist or may require 'docker login': denied: requested access to the resource is denied.

Fix as of now:

git clone git@github.com:siomiz/SoftEtherVPN.git
cd SoftEtherVPN
docker build -t siomiz/softethervpn:alpine -f Dockerfile.alpine .

siomiz, would you be so kind as to enable multi-arch builds for DockerHub so the arm64 image would be available to everyone?

[siomiz]

Ok, I think I did the manifest thing right...
siomiz/softethervpn:latest and siomiz/softethervpn:alpine have linux/arm64/v8 now.
(I'm assuming there is no such thing as linux/arm/v8?)

[paskal]

It works alright, thank you!

[paskal]

Actually, judging by my other image built using docker buildx, I think there should be no /v8 part in, so your `latest` should have the same image as `latest-arm64` has currently, with the same arch.

[siomiz]

Thank you for confirming!
I kinda cheated by building the arm64(/v8) image on an actual ARMv8 device, a Raspberry Pi 4B using 64-bit RasPi OS.
Built and pushed the :arm64-latest image, and created a new manifest for :latest + --amend and that somehow added the /v8 variant tag. Interesting spec...

[paskal]

You can build both architectures on amd64 Linux by issuing the following command: docker buildx build --pull --platform linux/arm64,linux/amd64 -t siomiz/softethervpn:latest --push ., and if it works as expected - include it into the CI pipeline. Here is documentation.

Can you add armv7 too?
you can extend your github workflow by adding buildx: https://github.com/maltegrosse/keycloak-multiarch/blob/main/.github/workflows/container.yml#L36

and later add
platforms: linux/amd64,linux/arm64,linux/arm

[siomiz]

Thanks everyone, finally figured out how workflow works with docker buildx...
