NVIDIA-1526 DPF: Test GPU operator

[josecastillolema]

Summary by CodeRabbit

Adds DPF CI configuration for the rh-ecosystem-edge/nvidia-ci repository. The configuration builds the nvidia-ci image from Containerfile and uses the OpenShift DPF CI base image.

Adds an optional GPU Operator end-to-end test for the metal-dpf-doca8 cluster profile. The test loads the hypervisor kubeconfig, then runs make run-tests with the nvidiagpu feature. It sets NVIDIAGPU_PRECOMPILED_DRIVER_BRANCH to all and NVIDIAGPU_USE_PRECOMPILED_DRIVER to false.

The test requests 2 CPUs and 2 GiB of memory and has a two-hour timeout. The configuration selects OpenShift prereleases from 4.22.0-0 up to 4.23.0-0 on the 4-stable stream.

Walkthrough

The change adds Prow configuration for the dpf variant of rh-ecosystem-edge/nvidia-ci. It defines the image build, OCP release selection, resource settings, and an optional GPU operator end-to-end test.

Summary

DPF build and test configuration ci-operator/config/rh-ecosystem-edge/nvidia-ci/rh-ecosystem-edge-nvidia-ci-main__dpf.yaml

Configures the nvidia-ci image build and selects OCP prereleases from 4.22.0-0 up to 4.23.0-0 in the 4-stable stream. Sets resource defaults and adds an optional GPU operator E2E test on metal-dpf-doca8. The test loads the hypervisor kubeconfig, sets GPU operator environment values, and runs make run-tests with a two-hour timeout. The configuration identifies the main branch, repository, and dpf variant.

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~10 minutes

Change: Feature

Merge Risk: 🔵 Low · up to 231fd

Changes to the DPF Containerfile will not automatically trigger its variant-specific image build, so the image may remain stale unless manually triggered. This is a bounded CI workflow gap with a manual workaround.

Full details: No-Sensitive-Data-In-Logs

Explanation

The new DPF GPU test activates dpf-hypervisor-load-kubeconfig through the changed config at ci-operator/config/rh-ecosystem-edge/nvidia-ci/rh-ecosystem-edge-nvidia-ci-main__dpf.yaml:53. That step logs the cluster-profile REMOTE_HOST value at ci-operator/step-registry/dpf/hypervisor/load-kubeconfig/dpf-hypervisor-load-kubeconfig-commands.sh:11,23,27. The profile is an external metal-dpf-doca8 profile backed by a cluster secret, so this can expose an internal host name or address in public job logs. The generated presubmit job confirms that this new test is runnable (ci-operator/jobs/rh-ecosystem-edge/nvidia-ci/rh-ecosystem-edge-nvidia-ci-main-presubmits.yaml:7554-7641).

🟡 Minor · Trigger the DPF image job when Containerfile… · rh-ecosystem-edge-nvidia-ci-main__dpf.yaml:11-15

ci-operator/config/rh-ecosystem-edge/nvidia-ci/rh-ecosystem-edge-nvidia-ci-main__dpf.yaml:11-15
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Trigger the DPF image job when Containerfile changes.

x^ matches no repository path. Because pull-ci-rh-ecosystem-edge-nvidia-ci-main-dpf-images is not always run, changes to Containerfile do not start the image build through the normal presubmit path. Set the selector to the image input path. The manual /test dpf-images trigger remains available.

Suggested fix

-  run_if_changed: x^
+  run_if_changed: ^Containerfile$
