incompatible with archlinux image on github actions

[ejose19]

Running docker buildx build results in failures related to actions/runner-images#2698, actions/runner-images#2658 & https://bugs.archlinux.org/task/69563.

I'm aware of the workaround of using latest runc as in actions/runner-images#2698 (comment), and even setting --oci-worker-binary=/usr/local/sbin/runc to not avail.

Bear in mind that docker build is able to work properly (with latest runc), so the issue must be related with buildx.

Latest buildkit version should not have issues except for 32bit platforms that need #1955 afaik. https://github.com/moby/buildkit/blob/v0.8/vendor/github.com/docker/docker/profiles/seccomp/default.json#L97 defines fsaccessat2 so new runc is not needed. Runc update in #1998

I've tried both moby/buildkit:master and moby/buildkit:latest with the same result, here's are the logs of the latest failed run.

I will try again once #1998 is merged to see if the issue is resolved.

https://github.com/moby/buildkit/releases/tag/v0.8.2 should have latest runc

note that you need --driver-opt image=moby/buildkit atm while we are still validating the release

Yes, I used driver-opts: image=moby/buildkit:latest in docker/setup-buildx-action@v1 and it seems it solved the issue, thanks @tonistiigi!
