OCI Kubernetes Engine (OKE) support for Compute Host Groups and Compute Clusters

Kubernetes Engine now supports the selection of compute host groups as a capacity type for the compute instances hosting worker nodes in node pools in a Kubernetes cluster. Compute host groups are useful for node pools that use bare metal shapes and require dedicated host placement or quick recycle behavior. Use this capacity type when you want the Compute service to place worker node instances on hosts in a specific compute host group. Before you can select a compute host group for a node pool placement configuration, the compute host group must already exist and be active. For more information, see Using Compute Host Groups to Provision Managed Nodes.

Kubernetes Engine also now supports the use of compute clusters to provision managed nodes. Use compute clusters for managed node pools that run workloads requiring RDMA-capable networking, such as distributed training workloads. Specifying a compute cluster for a managed node pool enables you to use RDMA-capable networking while retaining Kubernetes Engine managed node pool operations, such as scaling, upgrades, and node replacement.
