The PXB ARM64 backup tests run x86_64 helper containers (Minio, Vault, KMIP) on the docker-32gb-aarch64 label, served by the ec2-fleet Graviton pool. The worker bootstrap installs and starts docker but no x86 emulation, so those containers fail with exec format error. - Extract the static qemu-x86_64 from a digest-pinned image in Percona's ECR Public mirror (no EPEL dependency on Amazon Linux 2) and register a binfmt_misc handler in the shared arm fleet launch-template user-data. - Authenticated ECR Public pull (worker role grants the token); bounded retry so a pull failure degrades to no-emulation instead of hanging boot. - printf (not echo) emits the binfmt magic verbatim under any shell; magic, mask, and POF flags match the canonical qemu-x86_64 registration; the F flag opens the interpreter for container mount namespaces. - Mount/modprobe binfmt_misc before writing the register node. - Replace find | xargs with find -exec in the awscli cleanup (shellcheck). Applies fleet-wide via the shared jenkins-arm-fleet module. Consumer PXB-3613.

qemu-x86_64binfmt handler so x86_64 helper containers (Minio, Vault, KMIP) run under emulation on thedocker-32gb-aarch64label.Why
exec format error.ec2FleetCloud.groovy), whose workers boot from this shared launch-template user-data, so the qemu setup belongs here, not the classicinit.groovy.dcloud.qemu-x86_64is extracted from a digest-pinned image in Percona's ECR Public mirror (no EPEL dependency on Amazon Linux 2); pull is authenticated and bounded, registration usesprintfwith canonical magic/mask and thePOFflags.jenkins-arm-fleetmodule.Tickets
