Feature Overview

Goals

With the planned upcoming support in OpenShift for Kueue (https://kueue.sigs.k8s.io/) we also propose to enable RHACM to be able to utilise Kueue constructs for a multicluster environment via MultiKueue. By adding Kueue and using the management abilities they are already familiar with and using in RHACM our customers will be able take advantage of MultiKueue deployments using existing workflows.

Requirements

This Section: A list of specific needs or objectives that a Feature must
deliver to satisfy the Feature.. Some requirements will be flagged as MVP.
If an MVP gets shifted, the feature shifts. If a non MVP requirement slips,
it does not shift the feature.

Use Cases

• As an admin I want to manage as much of my multicluster environment from a single pane of glass as is humanly possible.
• As an admin, I want to use OpenShift’s support for Kueue for managing workload scheduling across multiple clusters managed by RHACM.
• As an admin I want to interact seamlessly with Kueue through RHACM constructs such as Placement and ApplicationSets (and others).
• As an Admin I want to be able to create RHACM Placement decisions and have RHACM generate corresponding MultiKueueConfig and MultiKueueCluster resources.
• Additionally, RHACM should be able to update MultiKueue dynamically.
• As an Admin I want to be able to manage and monitor my Kueue resources through RHACM APIs as well as the RHACM UI so I can automate the process as well as manage it visually.
• As an admin I want to be able to take advantage of Kueue integration with RHOAI for AI workloads via RHACM.
• As an OPP admin I want to get the most value I can out of integrations provided by my extended platform product.

Questions to answer
