nydus: support non-x86_64 arch test

[liubin]

Now, nydus only provide x86_64 binaries so tests only x86_64 now.
After nydus supports multiple arches, the nydus test should also support the new arch.

Hi @liubin - Can you provide more details on this? Looking at https://github.com/dragonflyoss/image-service/tree/master/app#support shows:

Platforms:

• x86_64
• aarch64

... and I don't see any arch-specific rust code in that repo...?

Hi @jodh-intel image-service now provides only x86 releases, for testing under aarch64, we should build it ourselves.

Ah - thanks for explaining @liubin.

Hi @liubin -, I test virtio-fs-nydus in kata on arm64 locally and it works. But there is no multi-arch nydus image in ghcr.io/dragonflyoss/image-service/. Can you help give a arm64 image instance there then we can enable nydus test on arm64.

@jongwu We can build one in nydus daily CI, will feedback once it is ready.

Thanks! @imeoer

Hi @jongwu @liubin, we built some nydus multiple arches (linux/amd64 and linux/arm64) images in daily CI.

These images can be found here: https://github.com/orgs/dragonflyoss/packages?repo_name=image-service

Maybe use ghcr.io/dragonflyoss/image-service/alpine:nydus-nightly-v6 for the test, but it requires nydusd v2.1.4, is there any obstacle in the test for this version requirement?

@imeoer -, Great! let me try it.
