* Fix(manifests): Upgrade rbac.authorization.k8s.io from v1beta1 to v1 (#6261) * proposal: Extend Notebook Controller to expose idleness for Jupyter (#6295) * proposal: Extend Notebook Controller to expose idleness for Jupyter (#6270) Provide a design doc as a proposal for extending Notebook Controller to expose idleness for Jupyter. Our proposal is in markdown format and follows the guidelines of the kubeflow/components/proposal/README.md guide. You can view the #6270 issue in the following link: #6270 Signed-off-by: Athanasios Markou <athamark@arrikto.com> * review: change the title of the proposal Change the title of the proposal to only include the proposed new feature. The new title of the proposal will now be "Expose Idleness Information for Jupyter Notebooks". * review: rename the proposal markdown file We want to give a more specific name to the markdown which contains the proposal. Since this proposal emphasizes on a feature regarding the Jupyter Notebooks, the new name will be: 20220121-jupyter-notebook-idleness.md * Synchronize jupyter-web-application role with clusterrole (#6241) * Update role.yaml * Update role.yaml * Update cluster-role.yaml * Kubeflow Roadmap update - with 1.5 details (#6266) * Kubeflow Roadmap update - with 1.5 details These proposed changes include: identifying that 1.4.1 has been delivered, provides themes for 1.5 and provides details of major features in 1.5 by working group. This is an initial proposal that needs review by the working group leads. * correct formatting in KFP features Moved KFP features under KFP Control Flow doc * updating KFP section updating KFP references with updates from KFP team * Updated the 1.5 release date to March updated the 1.5 release date to March * Update ROADMAP.md change Hyperparameter leader election to Katib leader election Co-authored-by: Andrey Velichkevich <andrey.velichkevich@gmail.com> * Update ROADMAP.md improve description and details of feature for metrics collector Co-authored-by: Andrey Velichkevich <andrey.velichkevich@gmail.com> * Update Katib description for Early stopping in 1.5 updating with Andrey's suggestion (but without the world proper). * Validation for Early Stopping algorithm settings helps users to proper reduce model overfitting Co-authored-by: Andrey Velichkevich <andrey.velichkevich@gmail.com> * notebooks: Extend Notebook Controller to expose idleness for Jupyter (#6297) * notebooks: Update image's tag in make Modify Makefile to update properly the TAG based on the git TAG.

I.e. the UI will be sending a PVC object in json format, so the backend will need to create the corresponding client.V1PersistentVolumeClaim object and submit it.

The backend will need to check that both the Notebook and the PVCs can be created beforehand. This way we avoid the scenario where we create PVCs but the Notebook fails to be created, and the PVCs are never garbage collected.

The backend will need to provide this information to the frontend. We don't want to send the K8s list of PVCs since this will result in a lot of unnecessary data to be sent.

Refs https://github.com/kubeflow/kubeflow/blob/master/components/proposals/20220121-jupyter-notebook-idleness.md Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com> * notebooks: Graceful handling of events (#6338) * notebooks: Handle events gracefully The controller is not exiting the reconciliation loop after it has re-emitted a Pod/STS Event as a Notebook Event. This results in the controller to later on try and GET a Notebook with the name of the Event that triggered the reconciliation loop. The controller should exit the reconciliation function once it has emitted the event. Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com> * notebooks: Don't reconcile on deleted events We don't want to trigger the reconciliation function when an event gets deleted. If a Notebook would be deleted then the underlying events would be deleted as well, which results in the reconcile function to get triggered and try to GET Events and Notebooks with the name of the deleted event. Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com> * notebooks: Fix endless restarts (#6341) * notebooks: Update notebook if timestamp changed We don't want to be updating the spec of the notebook if the timestamp hasn't changed, since this will lead to constant updates and reconciliation loops. Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com> * notebooks: Use a deep-copy of the notebook spec The controller should use a deep-copy of the notebook spec when calculating the spec for the StatefulSet. If not then we could update the notebook object without wanting it, since the spec could have been changed when calculating the STS spec. Signed-off-by: Kimonas Sotirchos <kimwnasptd@arrikto.com> * notebooks: Add prefix env var only if missing The controller should be setting OR updating the NB_PREFIX env var. Previously it would always blindly append it to the spec, which could result in double entries for the same env var.
