Good morning, I asked this on the kubic list already, but we found no solution, hence once again in a broader round: How to setup binfmt properly so one can build multi-arch containers with buildah/podman or docker buildx? https://podman.io/blogs/2021/10/11/multiarch.html This is what I found and tested so far: 1. Try to build without any binfmt things:
$ buildah bud --arch arm64 . STEP 1/2: FROM registry.access.redhat.com/ubi8:latest STEP 2/2: RUN uname -a exec /bin/sh: no such file or directory error building at STEP "RUN uname -a": error while running runtime: exit status 1 ERRO[0003] exit status 1
2. Setup binfmt Install qemu-linux-user. Check the proc directory:
# ll /proc/sys/fs/binfmt_misc/ total 0 --w------- 1 root root 0 Mar 10 09:45 register -rw-r--r-- 1 root root 0 Mar 10 09:45 status
Run "/sbin/qemu-binfmt-conf.sh --persistent yes --systemd ALL" followed by "systemctl start systemd-binfmt":
# ll /proc/sys/fs/binfmt_misc/ total 0 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-aarch64 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-aarch64_be -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-alpha -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-arm -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-armeb -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-hexagon -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-hppa -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-m68k -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-microblaze -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-microblazeel -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mips -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mips64 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mips64el -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mipsel -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mipsn32 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-mipsn32el -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-or1k -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-ppc -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-ppc64 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-ppc64le -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-riscv32 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-riscv64 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-s390x -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-sh4 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-sh4eb -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-sparc -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-sparc32plus -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-sparc64 -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-xtensa -rw-r--r-- 1 root root 0 Mar 11 08:42 qemu-xtensaeb --w------- 1 root root 0 Mar 10 09:45 register -rw-r--r-- 1 root root 0 Mar 10 09:45 status
3. Try building again The buildah call still does not work, but now I get another error message...
$ buildah bud --arch arm64 . STEP 1/2: FROM registry.access.redhat.com/ubi8:latest STEP 2/2: RUN uname -a error building at STEP "RUN uname -a": error while running runtime: exit status 255 ERRO[0003] exit status 255
I do not want to run a binfmt-docker-container that "does things" to install it, but I failed to find a nice tutorial on how to set this up (on openSUSE). I found lots of outdated tutorials for Ubuntu, and it seems to boil down to installing the qemu-binfmt package and then enable things. Does anyone have a link at hand that I missed in my searches? Which step did I miss? OS is Tumbleweed 20220308 Thanks in advance!
