      resources:
        reservations:
          devices:
          - driver: nvidia
            count: 1
            capabilities: [gpu]
  testgpupodman_deviceid:
      image: docker.io/ubuntu:latest
      command: ["nvidia-smi"]
      deploy:
        resources:
          reservations:
            devices:
            - driver: cdi

cdi devices

This test copies a CDI device file on a tmpfs mounted on /etc/cdi, then checks that the CDI device in the compose file is present in a container. The test is skipped when running as rootless.

Validation

  • The CDI device is present in the container.
