Spec fields

  • replicas: The number of desired replicas of the network function. Defaults to 1 if not specified.
  • selector: A label query over network function instances that should match the replica count. It must match the labels of the NetworkFunctionTemplate.
  • template: The template describing the NetworkFunction that will be created. It includes the metadata and specs of the network function, such as the P4 file, control plane configuration, and target selector.
  • minReadySeconds: The minimum number of seconds for which a newly created NetworkFunction should be ready without any of its container crashing, for it to be considered available. Defaults to 0 (the NetworkFunction will be considered available as soon as it is ready).

Status fields

  • replicas: The total number of non-terminated replicas that are currently running and ready.
  • fullyLabeledReplicas: The number of replicas that are fully labeled and ready.
  • readyReplicas: The number of ready NetworkFunction replicas.
  • availableReplicas: The number of available NetworkFunction replicas.
  • observedGeneration: The most recent generation observed for this NetworkFunctionReplicaSet. It corresponds to the generation of the most recently observed NetworkFunctionReplicaSet's desired state.
  • conditions: Represents the latest available observations of the NetworkFunctionReplicaSet's current state. It can include conditions such as ReplicaFailure, which indicates that one or more replicas failed to be created or deleted due to issues such as insufficient quota, limit ranges, target selectors, or driver issues.
