Hi @pkoutsov. Thanks for your PR.

I'm waiting for a opendatahub-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.

Hi @pkoutsov thank you for the PR, we have a new process to submit new components to Open Data Hub described here: https://github.com/opendatahub-io/opendatahub-community/blob/master/GuidelinesForNewComponents.md

If you can please also open an issue to add this component here: https://issues.redhat.com/secure/RapidBoard.jspa?rapidView=8528&projectKey=ODH&view=detail&selectedIssue=ODH-447

Also I wanted to see if there is a specific reason why this component was added to manifest and not odh-manifest?
Thanks
