Kubernetes clusters using ONAP Multicloud K8s Plugin Project for R4/R5 do not report hardware features to A&AI. Consequently during the CNF/VNF life cycle CNFs/VNFs that require or recommend specific hardware during instantiation cannot dynamically reach the correct cluster and node that provides the needed hardware capabilities.

Where needed add resource limits and request to ResourceBundle charts. I.E.:

  resources:
      requests:
        memory: "64Mi"
        cpu: "250m"
      limits:
        memory: "128Mi"
        cpu: "500m"

Instantiation of K8s HPA

See Deploying vFw and EdgeXFoundry Services on Kubernets Cluster with ONAP for instantiation flow for K8s. See https://docs.onap.org/en/latest/submodules/integration.git/docs/docs_vfwHPA.html?highlight=hpa VFW deployment with HPA for HPA use case.

  • Register K8s cluster internally with the K8s Plugin
• Add Node App in K8s Plugin to retrieve node labels from a cluster
• Identify and Address any gaps in policy and OOF to do match making of CNFs/VNFs using K8s Plugin
• Update CNF packages (Resource Bundles, CSAR) to include nodeSelector and resource requests and limits
• Update docs for HPA and K8s and Multicloud and ESR to reflect any change

As of now there are not any known gaps in OOF/Policy that would inhibit this from working.
