While I get that k8s isn’t supported, the official docker container also has a version (1.1.1-2) of beignet-opencl-icd that seems doesn’t include Coffee Lake support. It looks like the patches we need for Coffee Lake are in version 1.3.2-3 according to the Debian changelog , and Ubuntu seems to follow.
FWIW, I’m not running k8s, just a simple docker compose with the official container.
