Modify training-operator setup to be able to work along side mpi-operator

due to consolidation of MultiKueue adapters for the KFJobs

mszadkow · 2024-09-06T14:39:14Z

@alculquicondor I think everything from @mbobrovskyi was addressed

mbobrovskyi

Overall LGTM. Only this warning left:

# Warning: 'patchesStrategicMerge' is deprecated. Please use 'patches' instead. Run 'kustomize edit fix' to update your Kustomization automatically.

But I think we can fix it on follow-up.

Thanks!

+	cp -prf $(KF_TRAINING_ROOT)/manifests/* $(EXTERNAL_CRDS_DIR)/training-operator/
+	## Removing kubeflow.org_mpijobs.yaml is required as the version of MPIJob is conflicting between training-operator and mpi-operator - in integration tests.


Thanks for the details!

It makes me think that we need a note on this page https://kueue.sigs.k8s.io/docs/tasks/run/kubeflow/mpijobs/ explaining that you need to disable the MPI from training-operator if using both.

Why do we need this namespace? Are the tests creating any objects in it?

+    # 2. Training-operator deployment is modified to enable all kubeflow jobs except for mpi -  https://github.com/kubeflow/training-operator/issues/1777

+    # Modify the `newTag` for the `kubeflow/training-operator` to use the one training-operator version

Are you reverting these changes after testing?

Like here:

kueue/hack/multikueue-e2e-test.sh

Line 109 in 467b4ee

(cd config/components/manager && $KUSTOMIZE edit set image controller="$IMAGE_TAG")

kueue/hack/e2e-common.sh

Lines 97 to 99 in 467b4ee

function restore_managers_image {

(cd config/components/manager && $KUSTOMIZE edit set image controller="$INITIAL_IMAGE")

}

If not, users may accidentally commit unnecessary changes to this file.

I don't, good point I will add the restore

isn't this file outside of the tracked files?

No. It's on the git and yq will edit this file.
