Summary

i686 tests on x86_64 workers currently run in the default x86_64 image, because no docker_image_overrides are configured in prod. The i686 packages end up installed on a multilib x86_64 system. There, dnf refuses to pull an i686 dependency when the x86_64 package of the same name has a different version, so tests fail with errors like:

package infiniband-diags-1:61.0-2.el10_2.i686 from AlmaLinux-10-i686-96041-br requires libibumad(x86-32) = 1:61.0-2.el10_2, but none of the providers can be installed
  - libibumad-1:61.0-2.el10_2.i686 from AlmaLinux-10-i686-96041-br  does not belong to a distupgrade repository
  - conflicting requests

I reproduced this in an x86_64 almalinux:10 container. The same install succeeds in the native quay.io/almalinuxautobot/almalinux:10 image for linux/386.

Changes

• inventories/alts/group_vars/celery_x86_64.yml: new group vars that set docker_image_overrides for AlmaLinux 8, 9 and 10 on linux/386, using quay.io/almalinuxautobot/almalinux.
• inventories/alts/hosts.yml: new celery_x86_64 child group under celery, so only x86_64 workers get the override.
• playbooks/templates/alts_service_config.yaml.j2: docker_image_overrides is now rendered as block YAML instead of a one-line JSON list. Versions are forced to strings.

Notes

• EL8 and EL9 i686 tests also move to i386 images, because prod had no override before. Their results may change.
• To deploy, add the same celery_x86_64 group to the prod inventory, then run playbooks/alts_celery.yml --limit celery_x86_64 --tags celery-config. Restart alts-celery on those hosts afterwards.
• Workers keep pulled images locally (keep_locally = true). If a worker still runs i686 tests on x86_64, run docker rmi on that worker.

Testing

• ansible ... -m debug -a var=docker_image_overrides: defined only for x86_64 workers, undefined for aarch64, s390x and ppc64le.
• Rendered the template block with the template module and parsed it back with from_yaml. The data matches the group vars.
• --diff --check against the prod workers shows only the new docker_image_overrides block in celery.yaml.
