The "2" tag is very old and not a multi arch manifest. As such testing on aarch64 failed because it pulled and x86_64 image instead. This was found in downstream RHEL testing. The "2.8.2" is multi arch and used in podman testing were we successfully run aarch64 based testing. Signed-off-by: Paul Holzinger <pholzing@redhat.com>
