feat: (IAC-1155) Add Support for Setting up SAS Workload Orchestrator #483

Closed jarpat closed 1 year ago

jarpat commented 1 year ago

Changes

Adds the new V4_WORKLOAD_ORCHESTRATOR_ENABLED flag (default true) which will enable the SAS Workload Orchestrator service and configures the required ClusterRole and ClusterRoleBinding used by the daemon. Setting this to false will disable the SAS Workload Orchestrator service entirely

Additional info: The SAS Workload Orchestrator Service is used to manage workload started on demand through the launcher service. As of cadence 2023.08 this feature is now deployed by default. The SAS Workload Orchestrator daemons require information about resources on the nodes that can be used to run jobs. In order to obtain accurate resource information, it requires a ClusterRole and a ClusterRoleBinding to the SAS Workload Orchestrator service account which will be automatically configured by this project if you set V4_WORKLOAD_ORCHESTRATOR_ENABLED to true.

Relevant SAS Documentation: https://go.documentation.sas.com/doc/en/itopscdc/default/dplyml0phy0dkr/n08u2yg8tdkb4jn18u8zsi6yfv3d.htm#p1vo217m7ffso5n11vxwsyycw4tg this contains paths to various READMEs within your sas-bases.

This flag is only applicable for cadences 2023.08 and newer, this flag will perform no action on older cadences.
