Google Kubernetes Engine v1 API - Class TopologyManager (3.34.0)

Reference documentation and code samples for the Google Kubernetes Engine v1 API class TopologyManager.

TopologyManager defines the configuration options for Topology Manager feature. See https://kubernetes.io/docs/tasks/administer-cluster/topology-manager/

Configures the strategy for resource alignment. Allowed values are:

• none: the default policy, and does not perform any topology alignment.
• restricted: the topology manager stores the preferred NUMA node affinity for the container, and will reject the pod if the affinity if not preferred.
• best-effort: the topology manager stores the preferred NUMA node affinity for the container. If the affinity is not preferred, the topology manager will admit the pod to the node anyway.
• single-numa-node: the topology manager determines if the single NUMA node affinity is possible. If it is, Topology Manager will store this and the Hint Providers can then use this information when making the resource allocation decision. If, however, this is not possible then the Topology Manager will reject the pod from the node. This will result in a pod in a Terminated state with a pod admission failure.

The default policy value is 'none' if unspecified. Details about each strategy can be found here.

The Topology Manager aligns resources in following scopes:

• container
• pod

The default scope is 'container' if unspecified. See https://kubernetes.io/docs/tasks/administer-cluster/topology-manager/#topology-manager-scopes
