Depends on #202 and still WIP.

@rootfs based on the flow here https://github.com/sustainable-computing-io/kepler/blob/main/.github/workflows/image-base.yml#L6, may you please create a branch base so that we can get a multi-arch kepler_base image built and pushed, so that this PR can move ahead. maybe, may you please grant my access to branch base also, I can fix any problems found quickly...

[rootfs]

@huoqifeng here you go

[rootfs]

@huoqifeng are you still working on it? this will be very helpful once we have arm64 support, thanks

[huoqifeng]

@rootfs Sorry, I was busy on other projects, hopefully, I can check it this weekend.

[rootfs]

@huoqifeng thanks! You don't have to get everything in this PR. If you can make your work in a good shape, I'll pick up where you have left and ping you for review later.

[huoqifeng]

@rootfs I think we need make sure https://github.com/sustainable-computing-io/kepler/blob/base/.github/workflows/image-base.yml work well as it will generate and push the base image, which is the base for multi-arch kepler images. I remembered I don't have permission to rebase and push the branch base. May you help grant my write access to this base branch?

[huoqifeng]

Lack of the permission to rebase branch base to main. anyone can help on that?

changed the base branch from main to base.

[rootfs]

the integration test log is missing, do you happen to know what failed in the test? @huoqifeng

[huoqifeng]

I think we need make base branch get built successfully first, unfortunately I don't have permission to rebase the base branch.

[rootfs]

@huoqifeng let's pick up the change and see if the build works in the base branch.
