Does katib support xgboost-operator?

[0as1s]

Hi, I checked the repo and issues but did not find an answer. Can I use katib to find optimal hyperparameters for xgboost-operator(https://github.com/kubeflow/xgboost-operator)?

I know katib can be used on xgboost. Can I simply modify the trialSpec part to run katib for xgboost-operator? Xgboost-operator's yaml file is similar to mpijob-horovod.yaml with one master and several workers.

Thanks a lot!

It can be supported. But I do not think it is supported now /cc @kubeflow/wg-automl-leads

@0as1s Since Katib supports all Kubernetes CR, that can be easily supported by following this doc: https://www.kubeflow.org/docs/components/katib/trial-template/#use-custom-kubernetes-resource-as-a-trial-template.
It would be great if we implemented this support in default Katib controller settings.

Let's keep this issue open and try to implement this feature in default Katib controller support, like we did with MPI operator.
