Normal Feature Overview (aka. Goal Summary)
This feature will introduce customization for cluster scheduler that allows customer to set profiles such as "HighNodeUtilization" to maximize node utilization and reduce cost.
Goals (aka. expected user outcomes)
Customers can pass valid profile option to their {cluster or machinepool} (TBD based on design) that changes the scheduler options for their workloads . This will allow parity between self-managed OCP and ROSA/OSD clusters.
Requirements (aka. Acceptance Criteria):
- Configurability at the machine pool level
- Applicable only to the machine pools or the worker nodes that customer create/manage
- Allow shorter range of values - default value to start
- The default value is standard/normal utilization
- an optional tested profile is at least "HighNodeUtilization"
- OCM UI, ROSA CLI, Terraform can configure this field.
Use Cases (Optional):
- Cluster administrators want to maximize compute utilization and decrease compute costs by extension
- workloads can be right-sized by customers within specifically sized machinepools or labellled machines
- Administrators have self-managed OCP clusters using this capability and following same operations across different environments is preferred for deployment of workloads to managed cloud services.
