Topology Manager Policy

It controls the topology management policy which improves container performance. Options:

• none: This is the default policy and does not perform any topology alignment.
• best-effort: With this policy, kubelet attempts to allocate CPUs and devices on NUMA nodes to a pod as best as it can.
• restricted: With this policy, kubelet allocates CPUs and devices on NUMA nodes only to a pod. If there are no requested resources on the NUMA nodes, Topology Manager will reject this pod from the nodes.
• single-numa-node: With this policy, kubelet only allocates CPUs and devices on exactly one NUMA node to a pod. If there are no requested resources on the NUMA node, Topology Manager will reject this pod from the node.
